Summary

A powerful 8.8-magnitude earthquake in Russia’s Far East triggered regional disruption across the Pacific Ring of Fire and coincided with rare volcanic activity. Russia’s Krasheninnikov volcano on the Kamchatka Peninsula erupted for the first time in roughly 400–600 years, sending ash up to 6 km high, accompanied by a magnitude ~7.0 quake and briefly lifted tsunami warnings; impacts to populated areas were limited as ash drifted over the Pacific. Satellite imagery also revealed tsunami-related damage to a floating pier at Russia’s Rybachiy submarine base, raising concerns about naval readiness. In parallel, Indonesia’s Mount Lewotobi erupted on consecutive days, blasting ash up to 11 miles, blanketing nearby villages, and sustaining its highest alert with a wide exclusion zone. Authorities across the region warned that moderate explosive volcanic activity could continue and advised coastal caution despite generally low wave heights.

Key Points

  • Krasheninnikov volcano erupted for first time in centuries after an 8.8 quake, sending ash up to 6 km with limited impact on populated areas.
  • A magnitude ~7.0 quake and brief tsunami warnings accompanied the Kamchatka eruption; small waves reached Japan and Alaska.
  • Satellite images show tsunami damage to a floating pier at Russia’s Rybachiy submarine base, prompting readiness concerns.
  • Indonesia’s Mount Lewotobi erupted on consecutive days, lofting ash up to 11 miles, prompting highest alert and a 4.3-mile exclusion zone.
  • Officials caution that moderate explosive volcanic activity may continue across the seismically active Pacific Ring of Fire.

Russian volcano erupts for first time in centuries

Russia’s Krasheninnikov Volcano in Kamchatka erupted for the first time in over 500 years, sending an ash plume up to 6 km high. Authorities say there’s no immediate threat to populated areas. The eruption, along with a subsequent 7.0 quake and tsunami warnings in parts of Kamchatka, may be linked to last week’s powerful 8.8 earthquake in the region. Residents in three coastal areas were advised to stay away from the shore despite expected low wave heights. The remote Kamchatka Peninsula lies on the seismically active Pacific Ring of Fire.

Russia’s Krasheninnikov volcano on the Kamchatka Peninsula erupted for the first time in roughly 400–600 years, sending ash about 3.7 miles high. The eruption followed a recent 8.8-magnitude regional quake and was accompanied by a 7.0 quake, briefly triggering a tsunami warning that was later lifted. Ash drifted east over the Pacific with no impact on populated areas. Officials reported activity decreasing but warned moderate explosive activity could continue. Historical eruption timing varies by source, citing either around 1463 or 1550.

Satellite images taken after a massive 8.8-magnitude earthquake and ensuing tsunami show damage to a floating pier at Russia’s Rybachiy submarine base, raising questions about the Pacific Fleet’s readiness. The footage highlights broader disruption from the quake and tsunami across the region, while related segments cover ongoing crises including Gaza’s humanitarian emergency, US and UN diplomatic efforts, and other global incidents.

Indonesia's Mount Lewotobi volcano erupts for second straight day | Fox News

Indonesia’s Mount Lewotobi Laki-Laki erupted for a second straight day, sending ash and volcanic material up to 11 miles high early Saturday after a 6.2-mile-high eruption on Friday. No casualties were reported, but nearby villages were blanketed with debris, including hot gravel thrown up to 5 miles from the crater. Seismic activity and drone observations indicate deep magma movement, with gas, rocks, and lava traveling up to 3 miles down the slopes. The volcano remains at its highest alert level, with a 4.3-mile exclusion zone, and residents are warned of potential rain-triggered lava flows. The eruptions follow July disruptions that affected Bali’s main airport. Indonesia, on the Pacific “Ring of Fire,” has 120 active volcanoes.

Russian volcano erupts after massive earthquake, first time in centuries | Fox News

After an 8.8-magnitude earthquake triggered Pacific-wide tsunami alerts, Russia’s Krasheninnikov volcano on the Kamchatka Peninsula erupted for the first time in centuries, sending ash about 3.7 miles (6 km) into the sky. Authorities said the ash plume drifted east over the Pacific with no populated areas affected and no ashfall reported in towns. A 7.0 quake accompanied the eruption, briefly prompting local tsunami warnings that were later lifted. Experts noted this as the first confirmed eruption in roughly 600 years, though the Smithsonian lists the last eruption as 1550. Moderate explosive activity may continue. Small tsunami waves reached Japan and Alaska.

First volcano eruption in 600 years 'may be linked to huge earthquake in Russia's far east' | World News | Sky News

Krasheninnikov Volcano in Russia’s Kamchatka Peninsula erupted for the first time in about 600 years, an event scientists suggest may be linked to a recent powerful earthquake in the region. The 8.8-magnitude quake earlier in the week, which prompted tsunami alerts across parts of the Pacific, was followed by activity at Klyuchevskoi, Kamchatka’s most active volcano, and now Krasheninnikov. The latest eruption coincided with a separate magnitude 6.7–7.0 quake near the Kuril Islands; authorities noted possible local tsunami waves but no wider warning was issued.
