After a major earthquake off the Alaska Peninsula, tsunami surveillance was announced in Hawaii.
According to the Honolulu Star Advertiser, the Pacific Tsunami Warning Center (PTWC) described the magnitude as 8.1, saying “an investigation is underway to determine if there is a tsunami threat in Hawaii.”
However, the United States Geological Survey (USGS) states that a magnitude 8.2 earthquake struck 56 miles east-southeast of Perryville, Alaska.
According to the USGS, the quake was about 29 miles below sea level.
Two preliminary magnitude 6.2 and 5.6 earthquakes occurred in the same area within 30 minutes of the first, according to the USGS report.
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.
