The USGS recorded more than 270 earthquakes in Alaska’s North Slope on Sunday, August 12 and Monday, August 13, 2018, including M6.4, the most powerful earthquake ever to hit the region. The previous most powerful quake in the North Slope was M5.2 registered in 1995.
State seismologist Mike West said that Sunday’s M6.4 earthquake hit an area 26 km (42 miles) E of Kavik River Camp and 213 km (343 miles) NE of Fairbanks at a depth of about 6 miles (10 km).
“It was the biggest recorded quake in the North Slope by a substantial amount. This is a very significant event that will take us some time to understand,” West told the Anchorage Daily News
