About 30 homes were evacuated.Ī police officer extinguished a fire that started in a house. The quake caused a gas leak that led to an explosion in one home and the evacuation of a neighborhood in the community of Kenai. The biggest aftershock on Sunday was 4.7, and West said a magnitude 5 or magnitude 6 aftershock was possible. “However, last night’s earthquake is significant because it was close enough to Alaskan’s population centers,” West said, adding that aftershocks could continue for weeks. Alaska often has larger or more powerful earthquakes, such as a 7.9 last year in the Aleutians.
He called it the strongest earthquake in this region of Alaska in decades. southern Alaska is well instrumented, and this earthquake is of the style and type that we would expect in this area.” “Some earthquakes have challenges associated with them, they are unusual or hard to monitor,” Alaska state seismologist Michael West said. The USGS initially reported the earthquake at magnitude 7.1, downgraded it shortly after to magnitude 6.8, before raising it back to 7.1.
The earthquake struck about 1.30am and was centered 53 miles west of Anchor Point in the Kenai peninsula, which is about 160 miles south-west of Anchorage, according to the US Geological Survey (USGS).
