JUNEAU (AP) — An earthquake of magnitude 6.9 was felt off Alaska’s coast on Monday. It was described by the Alaska Earthquake Center as an aftershock to a 8.2 quake that occurred in late July.
According to the Alaska Earthquake Center. Monday’s earthquake felt all over Alaska Peninsula and Kodiak Island.
It happened about 70 miles (115km) east from Chignik, which is home to about 90 Alaskan Peninsula residents. Chignik lies approximately 450 miles (725 km) southwest Anchorage, and 260 miles (405 kilometers) southwest Kodiak.
Natalia Ruppert said that although the center hadn’t received reports of serious damage, it also relies upon self-reporting. Jeremy Zidek, spokesperson for Alaska’s emergency management agency, stated that the office was contacting communities but had not received any reports of damage.
Twitter report by the U.S. Geological Survey had a preliminary magnitude of 6.8. It was later revised and reaffirmed to 6.9. This tie another earthquake that struck Alaska in August.
These 6.9 quakes are the strongest aftershocks recorded since the United States’ largest earthquake in 50 years, the magnitude 8.2 earthquake that hit south of the Alaska Peninsula on August 28. Although it was felt widely, the earthquake did not cause any major damage to the region most affected. According to the earthquake center, it was the largest earthquake in the United States since the magnitude 8.7 earthquake that struck the Aleutians in 1965.
Ruppert indicated that aftershocks resulting from the July earthquake could continue for many, many months.
She explained that the area is seismically active. It’s not surprising for a large earthquake to produce aftershocks larger than a magnitude 6.
