HONOLULU (Reuters) – Fast-moving lava from Hawaii’s Kilauea volcano forced officials to close part of a highway on Tuesday, and they warned that sharp, thin strands of volcanic glass fibers carried by the wind could injure eyes and lungs.

As lava crossed Highway 132, officials shut a stretch of road from Lava Tree State Park to Four Corners and told residents who had not evacuated to leave the area immediately.

The lava flow destroyed a farm where Kevin Hopkins and partners raise tropical fish and the ornamental carp known as koi. “It just came over and ate the farm, boiled the water out of the ponds,” Hopkins said.

Earlier on Tuesday, a small explosion of ash erupted from the summit of the volcano in a vertical plume some 15,000 feet (4,600 meters) high, the U.S. Geological Survey said, the latest outburst in a month of volcanic activity.

The agency warned that ash was drifting northwest and liable to affect anyone in the summit area. Hundreds of people have been ordered to leave the vicinity of one of the world’s most active volcanoes in its biggest eruption cycle in a century.

Kilauea entered its fourth week of what may be an unprecedented, simultaneous eruption at its summit crater and along a six-mile (9.7-km) string of fissures 25 miles (40 km) down its east flank.

Lava flows from multiple fissures have blocked roads and damaged dozens of buildings on Hawaii’s Big Island.

Lava has also destroyed more than 400 electric poles and other equipment, causing power outages, the utility Hawaii Electric Light reported. It is unclear how many homes and businesses were without power.

One fountain of lava rose more than 200 feet (60 meters) at times on Monday, the Geological Survey said.

Officials are on high alert for occasional earthquakes, though most have been small.

Lava has engulfed the heads of two wells that tap into steam and gas deep into the Earth at the 38-megawatt Puna Geothermal Venture electrical plant, which used to produce a quarter of the Big Island’s electricity. Its operator, Israeli-controlled Ormat Technologies Inc, said it had not been able to assess the damage.

So far no deaths have been blamed on the eruption, though a man’s leg was shattered when he was hit by a plate-size chunk of lava rock.

Residents fear the electrical plant’s deep geothermal wells may be explosive. Officials have said the power plant is safe but lava has never engulfed a geothermal plant anywhere in the world, creating a measure of uncertainty.

Contingency plans have been made for a possible helicopter evacuation of up to 1,000 residents in a coastal area south of the fissures should their last exit route, State Highway 130, become blocked by lava or become unsafe due to gaping cracks, County of Hawaii officials said.

At least 82 homes have been destroyed in the southeastern corner of Big Island and about 2,000 people have been ordered evacuated since Kilauea began erupting on May 3.

HONOLULU (Reuters) – A small explosion of ash erupted from the summit of Hawaii’s Kilauea volcano early on Tuesday morning in a vertical plume some 15,000 feet (4,600 meters) high, the U.S. Geological Survey said, the latest outburst in a month of volcanic activity.

The agency warned that ash was drifting northwest and liable to dust anyone in the summit area. Hundreds of people have been ordered to leave the vicinity of the biggest eruption cycle in a century of one of the world’s most active volcanoes.

Multiple fissures continue to spew up hot lava flows, which have blocked roads and damaged dozens of buildings on Hawaii’s Big Island.

One fountain of lava rose more than 200 feet (60 meters) at times on Monday, the Geological Survey said.

Officials are on high alert for occasional earthquakes, though none have been big enough so far to trigger a tsunami.

Lava has engulfed the heads of two wells that tap into steam and gas deep in the Earth’s core at the 38-megawatt Puna Geothermal Venture. Its operator, Israeli-controlled Ormat Technologies Inc, said it had not been able to assess the damag

So far no deaths have been blamed on the eruption, though a man’s leg was shattered when he was hit by a spatter of super-dense lava.

Residents fear the wells may be explosive. Officials have said the power plant is safe but lava has never engulfed a geothermal plant anywhere in the world, creating a measure of uncertainty.

Contingency plans have been made for a possible helicopter evacuation of up to 1,000 residents in a coastal area south of the fissures should their last exit route, be blocked by lava or become unsafe due to gaping cracks, County of Hawaii officials said.

Hawaii volcano belches new ash plume as geothermal wells secured

By Marco Garcia

PAHALA, Hawaii (Reuters) – The restive Kilauea Volcano belched clouds of ash into the skies over Hawaii’s Big Island twice more on Wednesday as civil defense authorities reported that pressurized geothermal wells at a nearby power plant had been spared from approaching lava.

The latest back-to-back upheavals of ash from the main summit crater of Kilauea — one before dawn and another several hours later — came on the 21st day of what geologists rank as one of the biggest eruption cycles in a century from one of the world’s most active volcanoes.

The earlier ash plume rose to a height of 8,000 feet (2,438 meters), while the later one reached about 5,000 feet (1,524 meters), authorities said.

Intermittent explosions of ash from the summit, believed to be driven by underground bursts of steam deep inside the throat of the crater vent, are occurring about twice a day, with smaller blasts in between, U.S. Geological Survey (USGS) vulcanologist Wendy Stovall told reporters.

The Hawaii County Civil Defense agency warned in its latest bulletin that residents downwind of Kilauea should take care to avoid exposure to ash, which can cause eye irritation and breathing difficulties, particularly in people with respiratory problems.

“The ash has just been nonstop every day since the summit has been erupting,” said Tiahti Fernandez, 24, as she sat in a car parked outside her father-in-law’s home in the tiny farming village of Pahala, 26 miles (42 km) southwest of the summit crater.

“Every day we have to wash our cars and wash down the patio because the ash just covers everything,” she said over the crowing of four roosters tethered to a chicken coop in the yard. “The air quality has been so bad that everybody has been walking around with a (dust) mask.”

A fine layer of brownish-gray ash coated vehicles and other surfaces, and an ash plume rising from the volcano summit was visible in the distance through the hazy air.

Emissions of sulfur dioxide gas, harmful if inhaled, also remained at high levels from newly opened lava-spewing fissures in the ground running through populated areas on the eastern flank of the volcano, authorities said.

“Residents in the affected area should be prepared to take leave of the area with little notice due to gas or lava inundation,” the civil defense bulletin warned.

CRISIS AVERTED AT GEOTHERMAL PLANT

One potential hazard that appeared to have been brought under control was at the Puna Geothermal Venture (PGV) plant, which provides about a quarter of the Big Island’s electricity.

Lava from an active fissure nearby had flowed onto the property early this week, posing the risk of toxic gases being released in the event molten rock encroached into any of several pressurized deep-underground wells.

Utility crews racing to quench the wells with cold water and plug them with mud had managed to mostly secure the site. The civil defense agency reported on Wednesday, “there is no immediate threat to any of the wells at PGV.”

The facility also received a respite from Mother Nature. Accumulations of cooled, hardened lava created a thick, 30-foot (9.14-meter) high wall of solid volcanic rock channeling fresh lava streams from fissures to the south, away from the PGV plant, USGS scientists said.

Authorities also were monitoring hazards from noxious clouds of acid fumes, steam and fine glass-like particles — called laze — emitted when lava flows pour into the ocean on the island’s southern end.

Laze — a term combining the words “lava” and “haze” — is formed when molten lava, reaching temperatures of 2,000 degrees Fahrenheit (1,093 Celsius), reacts with sea water. Although potentially fatal if inhaled, Stovall said the danger was confined to the immediate vicinity of laze plumes themselves.

Kilauea rumbled back to life on May 3 as it began extruding lava and sulfur dioxide emissions through a series of fissures, marking the latest phase of an eruption cycle that has continued nearly nonstop for 35 years.

The occurrence of new lava vents, now numbering about two dozen, have been accompanied by earthquakes and periodic eruptions from the summit crater.

At least 44 homes and other structures have been destroyed, and a man was seriously injured on Saturday when a chunk of lava shot out of a fissure and struck him in the leg.

Some 2,000 people remain under evacuation orders due to lava flows and sulfur dioxide gas. Civil defense officials said contingency plans for further evacuations were being prepared with National Guard officials in case they become necessary.

Hawaii faces new threat of fumes from volcano’s lava

PAHOA, Hawaii (Reuters) – Hawaii faced a new hazard on Sunday as lava flows from Kilauea’s volcanic eruption could produce clouds of acid fumes, steam and glass-like particles as they reach the Pacific, authorities said.

Civil defense notices cautioned motorists, boaters and beachgoers to beware of caustic plumes of “laze” formed from two streams of hot lava pouring into the sea after cutting across Highway 137 on the south coast of Hawaii’s Big Island late on Saturday and early Sunday.

The bulletins also warned that reports of toxic sulfur dioxide gas being vented from various points around the volcano had tripled, urging residents to “take action necessary to limit further exposure.”

Laze – a term combining the words “lava” and haze” – is a mix of hydrochloric acid fumes, steam and fine volcanic glass specks created when erupting lava, which can reach 2,000 degrees Fahrenheit (1,093 degrees Celsius), reacts with sea water, Hawaii County Civil Defense said in a statement.

“Be aware of the laze hazard and stay away from any ocean plume,” the agency said, warning that potential hazards include lung damage, as well as eye and skin irritation.

Under Sunday’s conditions, with strong winds and copious amounts of lava hitting the ocean, the laze plumes could extend as far as 15 miles (24 km), mostly along the coast and offshore, though the hazard would diminish the farther out to sea it blows, according to USGS geologist Janet Babb.

Authorities cautioned, however, that wind patterns can change abruptly. The U.S. Coast Guard was “actively monitoring” the area to keep away all vessel traffic except permitted tour boats, the civil defense office said.

Laze killed two people when a lava flow reached the coast in 2000, and even a wisp can cause eye and respiratory irritation, the U.S. Geological Survey said. Acid rain from laze has corrosive properties equivalent to diluted battery acid, the agency said.

The section of coastal Highway 137 and a nearby a state park in the area where lava was pouring into the ocean were both closed, and another road in the vicinity was restricted to local traffic as a precaution due to elevated levels of sulfur dioxide gas.

An air quality index for Kona, about 40 miles (64 km) northwest of the eruption site, was at “orange” level, meaning that older individuals and those with lung problems could be affected.

EARTHQUAKES, ASH ERUPTIONS

Kilauea, one of the world’s most active volcanoes, began extruding red-hot lava and sulfuric acid fumes through newly opened fissures on the ground along its eastern flank on May 3, marking the latest phase of an eruption cycle that has continued nearly nonstop for 35 years.

The occurrence of new lava-spewing vents, now numbering at least 22, have been accompanied by flurries of earthquakes and periodic eruptions of ash, volcanic rock and toxic gases from the volcano’s summit crater.

The lava flows have destroyed dozens of homes and other buildings, ignited brush fires and displaced thousands of residents who were either ordered evacuated or fled voluntarily.

The volcano has also fed a phenomenon called vog, a hazy mix of sulfur dioxide, aerosols, moisture and dust, with fine particles that can travel deep into lungs, the USGS said.

On Saturday, authorities reported the first known serious injury from the eruptions – a homeowner whose leg was shattered by a hot, solid lumb of lava called a “lava bomb” while standing on the third-floor balcony of his home.

Mark Clawson, a friend of the victim who did not want his name used, lives near where his friend was staying as caretaker, and heard screaming and saw the harrowing aftermath, he told Reuters.

Apparently a fiery 5-pound “lava bomb” about the size of a dinner plate was launched from a fissure about 200 yards from the house, Clawson said.

“Most of them (lava bombs) arc high in the air, but every now and again there’s one that gets shot like a rifle, more horizontal and that’s what happened here,” he said.

It also started a small fire, which Clawson helped douse.

He said doctors had to pick sharp, hardened fragments of lava out of the wound, but the prognosis is good for his friend.

With Highway 137 severed, authorities were trying on Sunday to open up nearby Highway 11, which was blocked by almost a mile of lava in 2014, to serve as an alternate escape route.

The Hawaii National Guard has warned of additional mandatory evacuations if more roads become blocked.

Officials at the Hawaii Volcano Authority have said hotter and more viscous lava could be on the way, with fountains spurting as high as 600 feet (182 meters), as seen in a 1955 eruption.

PAHOA, Hawaii (Reuters) – Hawaii’s Kilauea volcano spewed ash nearly six miles (9 km) into the sky on Thursday and scientists warned this could be the first in a string of more violent explosive eruptions with the next possibly occurring within hours.

“This has relieved pressure temporarily,” U.S. Geological Survey geologist Michelle Coombs told a news conference in Hilo. “We may have additional larger, powerful events.”

Residents of the Big Island were warned to take shelter from the ash as toxic gas levels spiked in a small southeast area where lava has burst from the ground during the two-week eruption.

The wind could carry Kilauea’s ash plume as far as Hilo, the Big Island’s largest city and a major tourism center, the County of Hawaii Civil Defense warned in an alert.

“Protect yourself from ash fallout,” it said.

Some Big Island residents had feared “the big one” after Kilauea shot anvil-sized “ballistic blocks” into the visitors’ car park on Wednesday and was rocked by earthquakes that damaged buildings and cracked roads in the park that was closed last week.

But geologists said the 4:15 a.m. (10:15 a.m. EDT) explosion was not particularly large and on a par with the last series of steam-driven blasts, which took place in 1924.

“The activity is such that they can occur at any time, separated by a number of hours,” Hawaiian National Volcano Observatory Deputy Scientist-In-Charge Steve Brantley told reporters on a conference call.

Geologists said it was extremely unlikely Kilauea would have a massive eruption like that of 1790 which killed dozens of people in the deadliest eruption to occur in what is now the United States.

Kilauea’s falling lava lake has likely descended to a level at or below the water table, allowing water to run on to the top of its lava column and create steam-driven blasts, they said.

“I don’t think there is a big one that’s coming,” said University of Hawaii vulcanologist Scott Rowland.

“I think it’s going to be a series of explosions similar to the one that happened this morning, and that’s based on what happened in 1924, which is really our only analog,” he said of the nearly century old event, which lasted 2-1/2 weeks and killed one person who was hit by a “ballistic block.”

On Thursday, a 21st fissure also opened in Leilani Estates while other fissures reactivated with lava, the Hawaii Civil Defense said in an alert.

ASH MASKS

A spike in toxic sulfur dioxide gas levels closed schools around the town of Pahoa, 25 miles (40 km) east of the volcano, where lava from giant cracks has destroyed 37 homes and other structures and forced about 2,000 residents to evacuate.

A change in wind direction caused gas spewing from fissures to drift northwest towards Pahoa, prompting National guard troops to don gas masks at a nearby road intersection, according to a Reuters reporter.

Pahoa fire station recorded a “red level” of sulfur dioxide, meaning the gas would cause choking and an inability to breathe, Fenix Grange of the Hawaii Department of Health told a news conference in Hilo.

“If it’s red, it’s get out of Dodge,” she said.

There have been no deaths or serious injuries reported during the current eruption.

Civil defense workers handed out one ash mask per family member in communities close to Kilauea to protect residents from the powdered rock, which is not poisonous but causes irritation to eyes and airways.

Volunteers handed out some 5,000 dust masks in less than three hours in the community of Kea’au, north of Pahoa at one of the four distribution points that were opened on Thursday.

“It was just thick, eyes watering kinda stuff,” said Glenn Severance, 65, a resident of Hawaii Paradise Park.

“I just wanted to have something,” said Severance, adding he knew the mask would not protect against toxic volcanic gases.

An aviation red alert was in effect due to risks ash could be carried into aircraft routes and damage jet engines, USGS said. Passenger jets generally cruise at around 30,000 feet, the height of Thursday’s plume.

Across the Big Island, home to 200,000 residents, people were encouraged to take caution driving, as ashfall can make roads slippery, and not go outdoors unless necessary.

But by 1:30 p.m. (7:30 p.m. EDT) reported ashfall was limited to only light, wet deposits about 3-4 miles (5-6 km) northwest of the summit, as rain over the volcano curbed the spread of ash.

Thursday’s eruption lasted only a few minutes, said Coombs who called it “a big event that got people’s attention, but did not have widespread impact”.

“Tall but small,” she said of Thursday’s plume.

‘Ballistic blocks’ shoot from Hawaii volcano, may mark start of violent eruptions

People watch as ash erupt from the Halemaumau crater near the community of Volcano during ongoing eruptions of the Kilauea Volcano in Hawaii, U.S., May 15, 2018. REUTERS/Terray Sylvester

By Terray Sylvester

VOLCANO, Hawaii (Reuters) – “Ballistic blocks” the size of microwave ovens shot from Hawaii’s Kilauea volcano on Wednesday in what may be the start of explosive eruptions that could spew huge ash plumes and hurl smaller rocks for miles (km), the U.S. Geological Survey said.

Such eruptions, last seen nearly a century ago, have been a looming threat since Kilauea, one of the world’s most active volcanoes, erupted nearly two weeks ago.

Explosions in Kilauea’s crater sparked an aviation red alert due to risks the ash plume could blow into aircraft routes and damage jet engines.

More explosions are expected and may be more powerful, the USGS warned. These steam-driven blasts could send a 20,000-foot (6,100-meter) ash plume out of the crater, hurling 10-12 ton boulders up to half a mile (800 meters) and scatter pebble-sized rocks over 12 miles (19 km), the USGS has said.

This type of eruption has the potential to carpet the Big Island in much thicker ash than current dustings and possibly spread the powder and volcanic smog across the Hawaiian islands and farther afield if it enters the stratosphere.

“This morning dense ballistic blocks up to 60 cm (2 feet) across were found in the parking lot a few hundred yards (meters) from Halemaumau (Kilauea’s crater),” the USGS said in a statement. “These reflect the most energetic explosions yet observed and could reflect the onset of steam-driven explosive activity.

A 4.2 magnitude earthquake at the volcano at 8.36 a.m. (2:36 p.m. EDT) prompted authorities to issue an alert reassuring rattled Big Island residents that there was no risk of a tsunami from the volcanic activity.

‘DISARRAY AND FRANTIC’

In the community of Volcano, just north of Kilauea’s crater, business was way down and people were on edge.

In just a few hours residents had been shaken by an earthquake, dusted with ash and for the first time since the start of the eruption smelled the rotten-egg stench of toxic sulfur-dioxide gas.

“They’re just in disarray and frantic,” Adele Tripp, an employee at the Kilauea General Store, said of other residents. She said she had lived in Volcano for 30 years and was not personally concerned as she trusted scientists to tell her when to get out.

Smog from Kilauea drifted north up the island chain as the districts of Kau, Puna, and North and South Hilo were told by the National Weather Service to expect ashfall. Hawaii County Civil Defense said a dusting of ash was visible on property and advised residents to avoid exposure to the powdered rock, which can cause irritation to eyes and airways.

There was no effect on air carrier operations to Hawaii on Wednesday, Federal Aviation Administration spokesman Ian Gregor said in an email.

Ash is a new hazard for Hawaii’s Big Island, already grappling with volcanic gas and lava that has destroyed 37 homes and other structures and forced the evacuation of about 2,000 residents from a small area in the southeast Puna district.

Lava has burst from 21 giant ground cracks or fissures and torn through housing developments and farmland, threatening two highways that are exit routes for coastal areas.

Several fissures shot lava into the air on Wednesday but one flow advanced only 100 yards (meters) toward coastal Highway 137, which remains around a mile (1.6 km) distant, County of Hawaii Civil Defense said in a statement.

No serious injuries or deaths have been reported from the eruption.

Indonesia evacuates residents, shuts airport after Java volcano erupts

JAKARTA (Reuters) – Indonesian authorities ordered people living near a volcano to leave their homes on Friday and a major city closed its airport after the 5,500 meter (18,000 ft) peak sent a column of steam and ash into the sky.

The Mount Merapi volcano on densely populated Java island is one of the most active in Indonesia and a series of eruptions in 2010 killed more than 350 people.

A disaster mitigation agency told residents living within a 5 km (3 mile) radius of the mountain to move to shelters, agency spokesman Sutopo Purwo Nugroho said in a statement.

He said that 120 people who had been hiking up Merapi were safe.

The airport in Yogyakarta, the nearest big city to the volcano, shut because of the threat from the ash, the state-owned aviation agency AirNav said in a statement.

The disaster agency described Merapi’s latest eruption as phreatic, which means magma heats up ground water and vapor is released under pressure.

The alert status on Merapi had not be raised, it said.

Indonesia raises aviation warnings after Sumatra volcano emits ash cloud

JAKARTA (Reuters) – Indonesia on Monday raised flight warnings around the Mount Sinabung volcano on Sumatra island to their highest level after it sent a towering plume of ash more than 7 kilometers (4.4 miles) into the air, its biggest eruption this year.

Areas around the crater of the volcano, located about 1,900 km (1,181 miles) northwest of the capital, Jakarta, have been off-limits for several years because of frequent volcanic activity.

The Bureau of Meteorology’s Volcanic Ash Advisory Centre (VACC), in Australia’s northern city of Darwin, issued maps on Monday showing an ash cloud heading in three directions from Sinabung, to the north, northwest and south-southeast.

Indonesia also upgraded its Volcano Observatory Notice for Aviation (VONA) to red, its highest warning, and said the ash-cloud top had reached 23,872 feet (7,276 meters), according to a ground observer.

Sinabung is about 75 km (47 miles) southwest of Kualanamu International Airport in Medan.

Nur Isnin Istianto, head of the regional airport authority, said Kutacane airport in Aceh province had been closed, but the wind direction allowed the airport of Kualanamu, Meulaboh and Silangit to remain open.

Sutopo Purwo Nugroho, a spokesman for Indonesia’s Disaster Agency, said the eruption began on Monday morning, accompanied by multiple earthquakes and showering surrounding villages with small rocks.

“In five districts it became dark with a visibility of about 5 metres,” he said in a statement.

No casualties were reported. The agency urged the public to stay out of a 7-km (4-mile) exclusion zone around the crater, and watch for further warnings, which could cover floods.

The 2,460-metre (8,071-ft) tall volcano is among Indonesia’s most active. When Sinabung erupted in 2014, more than a dozen people were killed and thousands were evacuated. Prior to recent times, its last known eruption was four centuries ago.

Warning level raised on another Japanese volcano a week after fatal eruption

Photo taken from a Kyodo News helicopter on January 23, 2018,

OKYO (Reuters) – Japan raised the warning level on another volcano on Tuesday, exactly a week after an dramatic eruption at another peak killed one man, injured nearly a dozen others and stranded scores of skiers – including foreign tourists – for several hours.

Japan’s Meteorological Agency lifted the warning on Zao, a cluster of volcanoes in northern Japan whose highest point is 1,841 meters (6,040 ft), to 2 from 1, meaning that people should avoid going near the crater.

“There is a possibility of a small-scale eruption,” the agency said in a statement, noting that a number of small earth movements were detected on Tuesday, along with a slight bulging of the ground in one area.

It also warned of the possibility that volcanic rocks could be thrown as far as 1.2 km in any eruption.

The announcement came a week after a member of Japan’s military was struck and killed when rocks from the sudden eruption of the Kusatsu-Shirane volcano rained down on skiers at a mountain resort in central Japan.

Video footage taken by skiers on the mountain, including some from Taiwan, showed black ash boiling up into the sky as stones plummeted down, some punching holes in the metal roof of a ski gondola. Eleven people were injured and around 100 skiers took refuge in a mountain hut for several hours until rescued.

Zao, like Kusatsu-Shirane, is a popular resort area famed for its “snow monsters,” created by water vapor freezing on trees in winter. Its slopes are packed with skiers in winter and hikers in other seasons.

Japan has 110 active volcanoes and monitors 47 of them around the clock. In September 2014, 63 people were killed on Mount Ontake, the worst volcanic disaster in Japan for nearly 90 years.

Philippine province declares ‘calamity’ as volcano lava spreads

Clouds partially cover Mayon volcano's crater as it spews a column of ash during another mild eruption in Legazpi City, Albay province, south of Manila, Philippines January 16, 2018.

MANILA (Reuters) – A central Philippine province declared a state of calamity on Tuesday as a volcano spewed lava that reached the limits of a six-km radius no-go zone and spread ash on nearby farming villages.

Mount Mayon, a volcano in Albay province in the coconut-growing central Bicol region, has been erupting since Saturday and the number of people fleeing their homes had more than doubled on Tuesday to about 25,000, said Albay Governor Al Francis Bichara.

The National Disaster Risk Reduction and Management Council gave a smaller estimate, saying there were close to 22,000 evacuees.

Placing the province under a state of calamity will give the province access to extra funds.

“This kind of eruption, it will take about weeks, so we have to sustain the operations in the evacuation centers,” Bichara told ANC news channel. “We need to use the calamity funds.”

The Philippine Institute of Volcanology and Seismology (Phivolcs) said it had recorded nine more tremors, four of which accompanied lava fountains, as pressure leads to lava flows and ash plumes.

It reiterated that the activity signified a possible hazardous eruption within weeks or even days from the near perfectly cone-shaped volcano.

The provincial government has also expanded its suspension of school classes to more towns around the 2,462-metre (8,077-foot) volcano, about 340 km (210 miles) southeast of Manila.

Class suspensions have allowed the government to use schools as temporary shelters.
