Region Affected by 7.3 Magnitude Earthquakes

On Wednesday, a strong 7.3-magnitude earthquake in southern Alaska caused widespread evacuations along the coast.

The epicenter of the earthquake, which was recorded by the U.S. Geological Survey at 12:38 p.m. local time (4:30 p.m. ET), was in the Pacific Ocean, close to the Alaska Peninsula and southeast of Sand Point, near the Shumagin Islands.

People from the Kennedy Entrance near Homer to Unimak Pass by Unalaska were urged to move inland or to a higher elevation by emergency notifications, which caused alarms to ring and cellphones to buzz. This prompted prompt action.

“We heard reports of bumper-to-bumper traffic early on, as people rushed to evacuate the spit,” said Rachel Lord, the mayor of Homer.

Issued Tsunami Alerts, Later Downgraded

Initially, Kodiak Island, the Alaska Peninsula, and the eastern Aleutians were among the coastal regions for which authorities issued tsunami warnings. Images from the impacted areas revealed deserted beaches and dwindling water levels, which could be warning signs of a tsunami.

Sea levels rose by roughly three inches as a result of the earthquake, according to NOAA tsunami coordinator David Snider.

He claimed that although a tsunami had been created, it was no longer dangerous. Officials warned, though, that slight variations in sea level might last for some time.

Shortly after the earthquake, a full tsunami warning was issued; however, within ninety minutes, it was downgraded to an advisory. Additionally, by 12:45 p.m. local time (6:45 p.m. ET), the advisory was withdrawn.

Increased Fear Along the Shore

Residents along the coast were advised to remain vigilant for at least 24 hours despite the cancellation of warnings because of the possibility of persistent wave fluctuations.

As a precaution, emergency shelters were set up at North Star Elementary and Kodiak High School.

A woman who had recently returned to Alaska after a 25-year absence posted a video of people in Seward rushing away from the coast on social media. As the video came to a close, she remarked, “Just hope we don’t get waved.”

Aftershocks and Professional Opinion

There have been over 20 aftershocks since the original tremor, the strongest of which had a magnitude of 5.2.

“The southern coastline of Alaska is one of the most earthquake-prone zones in the country,” said Michael West, a seismologist with the Alaska Earthquake Center, in an interview with Fox Weather.

In actuality, Alaska experiences four of every five earthquakes in the United States. Even though many tremors go unnoticed, Wednesday’s was particularly strong, he continued. “It appears that we were fortunate this time,” he remarked.

The Impact’s Scope

Other states, including Oregon and Washington, were not at risk of tsunamis, according to the National Weather Service.

According to the National Tsunami Warning Center (NTWC), the alert area covered roughly 700 miles, from Unimak Pass to 40 miles southwest of Homer.

Officials in the 5,200-person town of Kodiak were on high alert. Local officials urged residents of King Cove, a much smaller community of about 870, to relocate to higher ground if they were in flood-prone areas.

A Tribute to Alaska’s Seismic History

On June 10, 1996, a 7.2-magnitude earthquake struck close to the Andreanof Islands, marking the last time Alaska experienced an earthquake of that size.

The Great Alaska Earthquake of 1964, however, continues to stand as the most devastating earthquake in Alaskan and American history.

Seattle was affected by the devastating 9.2 magnitude earthquake that occurred close to Prince William Sound.

It caused tsunamis that reached as far as Hawaii, California, Oregon, and even Japan, destroying coastal communities throughout Alaska.
