A powerful earthquake triggered volcanic activity and tsunami alerts in Russia's Kamchatka region, highlighting ongoing seismic threats and regional instability.

The overnight eruption of the Krasheninnikov Volcano in Kamchatka, its first in 600 years, may be connected to the huge earthquake that rocked Russia’s Far East last week, Russia’s RIA state news agency and scientists reported on Sunday.

The Krasheninnikov Volcano erupted on Sunday, Aug. 3, marking the volcano's first eruption in 600 years. The eruption may be linked to the massive earthquake that hit Russia less than a week earlier and caused tsunami warnings in multiple countries.
