Two volcanoes in Indonesia have erupted sending thousands fleeing and destroying entire crops.

Mount Sinabung first erupted Thursday in the early morning hours sending a plume of ash 23,000 feet into the air in the Karo region of North Sumatra. The mountain then erupted again just before noon with an ash plume that rose 16,400 feet.

Government officials rushed at least 5,500 residents away from the area.

Then today Mount Sinabung was the second Indonesia volcano to erupt in a span of hours. Mount Merapi exploded just before 5 a.m. local time send a plume of ash 6500 feet into the air. Hours later, Mount Sinabung erupted stronger than ever with an ash cloud rising 26,500 feet into the air.

The Indonesian Transportation Ministry has issued a statement to all airlines telling them to avoid the airspace surrounding the volcanoes because of the ash and their current instability.

The ash from the volcanoes has destroyed the crops of farmers surrounding the mountain who depend on their crops to live. A local farmer told the Jakarta Globe the losses to farmers in the region could end up in the billions. He said some of the farm land has been so damaged by the volcanoes they can no longer be used for farming.

Indonesia is located on the Pacific Ring of Fire.
