Magnitude 6.1 Quake Hits Kamchatka, Follows Massive 8.7 Tremor

On the early morning of August 1, 2025, a powerful 6.1 magnitude earthquake struck off the coast of Russia's Far Eastern Kamchatka Peninsula. The aftershock, which occurred around 2:35 AM local time, was centered in the Pacific Ocean at a depth of 24 kilometers, approximately 239 kilometers away from the regional capital of Petropavlovsk-Kamchatsky.

This latest tremor follows a massive 8.7 magnitude quake that hit the Kamchatka region just last month, on July 30th. Authorities declared a state of high alert in the aftermath of the initial quake, which also triggered a tsunami warning across the Pacific.

According to the Geophysical Service of the Russian Academy of Sciences, the region has been experiencing a series of aftershocks ranging from magnitudes 4 to 5.9 over the past several hours, with the frequency gradually declining. In the first 24 hours after the initial 8.7 quake, aftershocks were recorded as frequently as every 5 to 10 minutes.

While the latest 6.1 magnitude tremor did not result in any reported injuries or significant damage, the ongoing seismic activity in Kamchatka continues to keep the region on high alert. Authorities remain vigilant as they monitor the situation and work to ensure the safety of local residents.
