Kuril islands: An earthquake of magnitude 6.7 struck Russia's Kuril Islands, reported the German Research Centre for Geosciences. The agency initially estimated the earthquake's magnitude at 6.35, with a depth of 10 kilometers (6.2 miles).

According to Emirates News Agency, the United States Geological Survey recorded the earthquake at a magnitude of 7. The Pacific Tsunami Warning System also reported the quake at 7.0 magnitude, but confirmed there was no tsunami warning following the event.

In a related incident, the Krasheninnikov Volcano in Kamchatka erupted for the first time in 600 years, as reported by Russia's RIA state news agency and scientists. This occurred overnight, coinciding with the recent seismic activities in the region.

Both the earthquake and the volcanic eruption follow a massive 8.8 magnitude earthquake that struck the same region days earlier, triggering tsunami alerts across Japan, Indonesia, Australia, the United States, and Chile. Russian scientists are investigating a potential connection between the volcanic eruption and last week's earthquake.

Olga Girina, head of the Kamchatka Volcanic Eruption Response Team, noted that this is the first confirmed eruption of Krasheninnikov Volcano in 600 years. She suggested a possible link between the eruption and the earthquake on Wednesday, which was succeeded by an eruption of Klyuchevskoy, Kamchatka Peninsula's most active volcano.
