Another earthquake was detected off the coast of Alaska, this time about 200 miles northwest of Attu Station. According to The U.S. Sun, the earthquake’s magnitude is 5.0.
The tremor was recorded near the Aleutian Islands, with a depth of 10km. In addition to being close to Alaska, it is also close to the Kamchatka Peninsula and Koryakia in Russia. This tremor is not an isolated incident, however.
As the Aleutian arc is a seismically active region, many earthquakes happen there every year. Over the past week, several tremors occurred. On Tuesday, two tremors of 4.8 and 5.6 were discovered about 50 miles closer to Attu Station. Another tremor with a magnitude of 4.4 happened around the same time.
At this time, there is no active tsunami warning. After the 5.6 magnitude earthquake, the US Geological Survey issued no additional tsunami warnings. While earthquakes are common in the region, only 12 had a magnitude over 7.5 on the Richter scale in the past century.
Alaska Earthquakes This Year
Earlier this year, Alaska experienced several major earthquakes. This summer, the region experienced a massive 8.2 magnitude quake. It was the strongest earthquake to hit the US since 1965. The tremor occurred around 495 miles southwest of the state’s largest city Anchorage. Interestingly, the aftershock generated smaller quakes of its own.
In October, Alaska suffered a 6.9 magnitude earthquake. The affected areas included the Alaskan Peninsula, the Kodiak Islands, and Chignik city. According to the USGS, the epicenter of the quake had a depth of 29 miles. No tsunamis developed as a result of October earthquake. Four other aftershocks with a magnitude of between 2.7 and 3.6 occurred around that time, but they caused no significant disturbances.
Other earthquakes of similar magnitudes occurred in Japan and Hawaii. In October, Hawaii experienced a 6.2 magnitude event. No serious damage resulted from the earthquake, and there was no tsunami. Seismologists discovered no link between the Hawaii and Alaska earthquakes.
In Japan, the first seismic activity in the region since 2011 struck Tokyo. The epicenter of the quake was east of Tokyo and nearby Chiba. At the time of the incident, thirty people reported injuries, with three in critical condition. While no tsunamis occurred, the area suffered some damages.
These damages were largely related to infrastructure. The force caused underground pipes to burst, and several hundred homes lost power. The quake also caused transportation disruptions, with trains and subways shut down. Unfortunately, one unlucky group of passengers were aboard a train that derailed as a result of losing power. Three of them experienced minor injuries.
Overall, the trains and subways were able to resume normal operations within a few days. However, commuters experienced longer lines because of the delays associated with the repairs.
