Earthquake of magnitude 7.3 jolts Alaska, advisory issued
PTC News Desk: An earthquake of magnitude 7.3 on the Richter Scale rattled Alaska in the early hours of Thursday (local time), a statement by the National Center for Seismology (NCS) said.
A tsunami warning was issued for parts of coastal Alaska after an earthquake in the Gulf of Alaska, according to the US Tsunami Warning System. However the warning was later reduced to advisory.
As per the NCS, the massive earthquake occurred at a shallow depth of 36km, making it susceptible to aftershocks.
In a post on X, the NCS said, "EQ of M: 7.3, On: 17/07/2025 02:07:42 IST, Lat: 54.91 N, Long: 160.56 W, Depth: 36 Km, Location: Alaska Peninsula."
Shallow earthquakes are generally more dangerous than deep earthquakes. This is because the seismic waves from shallow earthquakes have a shorter distance to travel to the surface, resulting in stronger ground shaking and potentially more damage to structures and greater casualties.
