5.9 magnitude earthquakeAlthough no immediate damage has been reported, Tuesday’s earthquake in Alaska left a rumbling sound across the region.
The earthquake, which occurred at 1:42 p.m. Alaska Standard Time, took place across the Cook Inlet from the Kenai Peninsula and 38 miles east of Port Alworth, which has a population of 186, according to 2020 estimates. It was centered about 140 miles southwest of Anchorage, the state’s largest city.
Seismologist Lea Gardine of the Alaska Earthquake Center told the Anchorage Daily News that no immediate damage was reported after the earthquake. The depth of the quake, about 95 miles from the surface, likely played a factor in minimizing damage.
“This one was on the deeper side,” Gardine said. “If it was more shallow, it definitely would have (caused damage), but it’s not uncommon for ones of this size, at this depth, to not cause any significant damage.”
The Richter Magnitude Scale shows that a 5.9 earthquake would be the most extreme.

The earthquake was felt throughout much of the nation’s largest state, with reports coming in from Fairbanks, Kodiak and Valdez, according to the Anchorage Daily News.
In 2016, a magnitude 7.1 earthquake struck nearby, destroying many homes on Kenai Peninsula. However Gardine stated Monday’s earthquake does not appear to immediately be an aftershock.
It is possible to expect smaller aftershocks. These are the National Tsunami Warning Center said it does not expect a tsunami.
The Alaska quake came just one day after a 6.2 magnitude earthquake shook part of northern California on Monday. Although the earthquake was felt along the coast, approximately 210 miles north of San Francisco it caused substantial shaking and was not expected to cause any major damage.
The nearest town to the earthquake is Eureka. It’s located approximately 45 miles north. Even residents as far as Sacramento and San Francisco Bay felt the quake’s effects.
