A magnitude 6.2 earthquake struck the Alaska Peninsula on Monday, according to the National Centre for Seismology (NCS). The quake occurred at a shallow depth of 48 kilometres, increasing the chances of aftershocks, the NCS noted in its statement.
In a post on X, the agency reported: “EQ of M: 6.2, On: 21/07/2025 03:58:02 IST, Lat: 54.99 N, Long: 159.98 W, Depth: 48 Km, Location: Alaska Peninsula.”
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.

On July 17, a powerful 7.3 magnitude earthquake struck the Alaska Peninsula, according to a statement from the National Centre for Seismology (NCS).
The quake occurred at a shallow depth of 36 kilometres, making it more prone to aftershocks, the NCS noted.
In a post on X, the agency stated: “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.
The Alaska-Aleutian subduction system is one of the most seismically active globally, producing more >M8 earthquakes over the last century than any other. Many of these earthquakes, as well as coastal and submarine landslides, create tsunamis. The region contains over 130 volcanoes and volcanic fields, and contains well over three-quarters of US volcanoes that have erupted in the last two hundred years.
