Volcanic Watch
Krasheninnikov Continues Effusive Activity
An effusive eruption at Krasheninnikov volcano in Russia remained ongoing as of June 7, 2026, with continued lava extrusion. This relatively quiescent eruption style presents lower immediate hazard compared to explosive activity.
Mount Merapi Avalanche-Triggered Seismicity
Mount Merapi in Indonesia recorded 127 earthquakes associated with avalanche activity during the monitoring period, reflecting ongoing instability on the volcano's slopes.
Kīlauea Summit Eruption Paused
Kīlauea volcano in Hawaii is not currently erupting as of June 7, 2026. The summit eruption in Halemaʻumaʻu crater has paused, though robust degassing and bright overnight glow persist at both vents. The volcano remains at YELLOW Aviation Color Code and ADVISORY alert level.
Sakurajima Major Eruption Disrupts Japan
On June 7, 2026, a major eruption at Sakurajima volcano in Kagoshima, Japan blanketed Kagoshima City with volcanic ash. The event forced flight cancellations, rail suspensions, and widespread tourism disruptions across the region, affecting Japan's most active volcano destination.
