Perryville, Alaska (AP) —Tsunami surveillance was announced in Hawaii on Wednesday night after a major earthquake off the Alaska Peninsula.
according to Honolulu Star AdvertiserThe Pacific Tsunami Warning Center described the magnitude as 8.1, stating that “an investigation is underway to determine if there is a tsunami threat in Hawaii.” However, according to the United States Geological Survey, the quake occurred at a magnitude of 8.2, 56 miles (91 km) southeast of Perryville, Alaska, at around 8:15 pm. According to the USGS, the quake was about 29 miles below sea level.
According to the US Geological Survey, two preliminary magnitude 6.2 and 5.6 quakes occurred in the same area within 30 minutes of the first quake.
The Pacific Tsunami Warning Center has issued a notice that potential threats to Guam and American Samoa are still under investigation.
“Based on all available data, the quake could have caused a tsunami and could be devastating even in coastal areas far from the epicenter,” said PTWC.
Based on preliminary seismic data, almost everyone at the epicenter should have felt the quake widely. It may have caused mild to moderate damage.
Moderate tremors probably occurred at Perryville, Chigic Lake, and Sandpoint.
