A 7.5 magnitude earthquake in Alaska has rocked the entire state. The intense Alaska earthquake triggered a tsunami warning and instantly prompted evacuation orders. The officials later cancelled the tsunami warning but have requested communities to be evacuated to higher grounds during the chaos.
The earthquake in Alaska had the North Pacific Ocean as the epicenter. As per the U.S. Geological Survey, the 7.6 magnitude earthquake was about 55 miles southeast of Sand Point at 12:54 p.m. and had a depth of 25 miles. The total area is about 575 miles southwest of Anchorage.
According to Michael West, State Seismologist, It is believed that the earthquake was an aftershock of the magnitude 7.8 quake that had the same epicenter in July. The earthquake triggered more than two dozen of its aftershocks shortly after, ranging from 3.5 to 5.9 magnitude. He has also warned that the citizens will witness aftershocks in days to come.
Paul Caruso, a geophysicist with the U.S. Geological Survey stated, “This is an area where the Pacific Plate is sub-ducting underneath the North American Plate. And because of that, the Pacific Plate actually goes underneath the North American Plate, where it melts, noting that’s why there are volcanoes in the region.”
The Alaska Earthquake Centre said the earthquake in Alaska was strongly felt in communities along the southern coast, including Chignik, Unalaska, Sand Point, and the Kenai Peninsula. The long-lasting earthquake in Alaska was felt most strongly in coastal communities, and its waves went as far away as Anchorage, Bethel, and Chugiak but no injuries have been reported so far.
Communities’ falling within the warning zone evacuated to higher ground for safety as the tsunami was expected to approach. Tsunami waves were expected to rise in Sand Point, the closest community to the quake, about an hour after the earthquake shook the town. Homer residents were also seen driving to higher ground after the evacuation orders were circulated.
Unalaska officials released an official statement calming the residents by saying that the city is just outside the warning zone and they aren’t ordering evacuations right now. Unalaska public safety officials earlier Monday had sent out a release saying they would be conducting tests of the community’s tsunami warning sirens.
Ladakh, located in the north Indian state of Jammu and Kashmir, also recorded an earthquake with a magnitude of 3.6 magnitudes in the wee hours of Monday morning. As per the NCB officials, the earthquake hit 110 kilometers north-north-west (NNW) of Kargil at a depth of 10 kilometers, and that there were no casualties.
The entire Himalayan Seismic zone is prone to earthquakes and this is the reason why Ladakh witnesses so many earthquakes. The Indian tectonic plate is constantly driving into the Eurasian plates around this region. Due to this recurrent motion of tectonic plates, the stress keeps building up, and hence earthquakes are triggered to ease the piling tension.
