Central Arizona was rattled Sunday night after experiencing 3 small earthquakes within a 3 hour period.

The United States Geological Survey (USGS) reported that the first earthquake had a 3.2 magnitude and struck just before 9 p.m. local time. At 11:29 p.m., a 4.1-magnitude earthquake struck the same area, and twenty minutes later, a 4.0-magnitude earthquake took place, according to Weather.com. No injuries or damages have been reported.

All three earthquakes were centered around Black Canyon City which is located about 45 miles north of Phoenix, and they ranged between 3-6 miles in depth.

“In general, it’s relatively small,” Zachary Reeves of the USGS said of the magnitude-4.1 peak earthquake Sunday, the largest of the series. “If people are in bed then people may not even be woken up by it.”

Residents in Phoenix did feel tremors from the quake. Geologist Michael Conway, chief of the Geologic Extension Service of the Arizona Geological Survey, told ABC News that central Arizona region has several inactive and active faults that reach throughout the state.

Since the USGS began keeping records of earthquakes, Arizona has seen 11 earthquakes of magnitude 4 or greater, and two of those 11 occurred on Sunday night.
