Large -scale earthquakes: 6.2 magnitude shock hit Alaska; No damage was reported
According to the National Center for Sisamology (NCS), the earthquake of Alaska’s magnitude on Monday. The earthquake occurred at a depth of 48 km, reflecting the potential afterchox due to its shallow nature.NCS posted on X: “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.”There is no harm yet.This is only a few days after NCS reported another earthquake in Alaska, which is recording 7.3 on the Richter scale. On July 17, the incident occurred at a depth of 36 km, which also suggests vulnerability for afterchox.NCS shared on X: “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: Alaskaka peninsula.”Shallow earthquakes pose a greater risk than deep people because their seismic waves travel short distance to reach the surface, resulting in more intense ground movement and increased structural damage and an increase in the number of casualties.The Alaska-Elutian subduction system ranks into the world’s most seismicly active areas, which records the highest number of earthquakes above 8 earthquakes in the last century. These seismic events and various landslides often produce tsunamis. The region features more than 130 volcanoes and volcanic regions, which is accounting for more than 75% active American volcanoes in the last 200 years.
