Why the earthquake in Alaska 7.3 was remarkable


Juneau, Alaska (AP) – The strength 7.3 of the earthquake on Wednesday in front of Alaska's Aleuten chain in a region that has a handful of the past five years Almost exactly two years earlier.

Officials said on Thursday that they had no reports of injuries or serious damage The latest eventWho triggered one tsunami warning that lasted about an hour before they were downgraded and the communities along a 700-mile route on the south coast of Alaska caused people to push people to move on a higher floor. Kara Sterling, a main scientist of the National Tsunami Warning Center, said the official maximum wave height in Sand Point, a community that was 55 miles north of the epicentrum north of the epicentrum. It occurred at low tide.

Earthquakes triggered Tsunami warnings

The earthquake met at 12:37 p.m. local time and prompted the center warning.

There are a number of ways of how people can receive notifications in warning areas, including the sound of sirens in communities that they have, hear the Weather radio or Public radio programsAccording to official reports on social media or push warnings on mobile phones. In some places, local officials have passed on warnings from door to door, said Jeremy Zidek, a spokesman for the state's emergency management department.

The departments for public security in King Cove and Unalaska have sent notifications that ask those in coastal areas or those who could be flooded to look for higher soil.

The warning published by the center was downgraded to a hint before it was canceled around 2:45 p.m.

Alaska is one of the world's most seismic regions in the world

According to the US Geological Survey, Alaska is the state -prone state in the USA and one of the world's most active regions in the world. The state experiences an earthquake of strength 7 almost annually, and the second largest earthquake that was ever recorded was centered about 155 miles east of Anchorage, said the agency. This earthquake from 1964 – and the tsunami he triggered – killed about 130 people.

The Aleuten is not a stranger for earthquakes, but the activity in the region in which the earthquake was beaten on Wednesday has attracted the attention of the scientists. The area, in a few hundred miles from the earthquake, has “illuminated” since 2020, with the earthquake marking the fifth on Wednesday Exceeds the size 7.0 since 2020said the state seismologist Michael West.

“I would not call this isolated earthquake. It seems part of a greater sequence that has extended in recent years,” he said. But West added: “There is no reason to be an alarmist.”

People should continue to consider warnings, say officials

Some municipalities have buildings that are shown on higher soil than meetup points during Tsunami warnings such as a school, while others simply urge the residents to withdraw to a hill, Zidek said.

“In this area of Alaska, most of the areas of Alaska, it gets steep very quickly,” he said.

Sometimes the only warning you might have is the trembling soil, said Zidek. “If it shakes violently for 20 seconds or longer, it is your warning sign and you should deal with the higher soil in a coastal area,” he said.

Zidek and West said people should continue to consider warnings. West said he was worried about a “burnout effect” among the residents of the region, some of whom have been evacuated several times since 2018 to respond to larger earthquakes that have not caused significant damage.

West said he was reminded of an earthquake of 8.6 in 1946 -west of the location of the quake on Wednesday -that created a deadly tsunami and led to the creation of a US tsunami warning system. According to the National Oceanic and Atmospheric Administration, the number of fatalities included more than 150 people in Hawaii.

“This area is able to transcify tsunamis, and I have the feeling that the best way to stay vigilant … Perhaps it is to examine our deeper history beyond the past five years,” he said.
