Semeru Volcano Eruption Continues in East Java, Indonesia: Everything You Need to Know
Ongoing eruptive activity at the Semeru Volcano in East Java, Indonesia, continues to pose a threat to local populations and travelers as of January 31, 2026. The Center for Volcanology and Geological Hazard (CVGHM/PVMBG) reports increasing activity, characterized by both seismic and explosive phenomena. This situation demands vigilance from those living near the volcano, tourists in the region, and surrounding communities.
Explosions and Seismic Activity
Seismic monitoring has recorded approximately 96 eruptions from Semeru, with no indication of a decline in activity. These explosions are crucial to monitor as they contribute to the ash and gas plumes being released. On January 30, the ash and gas plume rose to a height of 1000 meters (3281 feet) above the volcano’s vent.
Rockfalls and Potential Hazards
In addition to the explosions, three seismically recorded rockfalls have occurred. While rockfalls are common with active volcanoes like Semeru and may represent a less severe hazard than ash or lava flows, they still pose a risk to both air and ground travel. Travelers should be aware of potential disruptions and health hazards related to ash exposure.
Travel Advisories and Restrictions
Due to the continued eruptions, travel advisories are in effect for East Java, Indonesia. Travel within areas affected by ash and eruptions is restricted. The PVMBG advises all individuals in impacted zones, including visitors, to exercise caution and closely monitor the volcano’s activity.
