The Semeru Volcano in East Java, Indonesia, is exhibiting significant eruptive activity as of January 30, 2026, disrupting travel and posing a potential hazard to surrounding communities. The Center for Volcanology and Geological Hazard (CVGHM/PVMBG) reports increasing activity, characterized by both seismic and explosive phenomena.
Explosions and Seismic Activity
Approximately 96 seismically recorded eruptions have occurred at Semeru, with no indication of decline in the volcanic activity. Monitoring explosions is crucial for tracking ash and gas plumes produced by the volcano.
Rockfalls and Seismic Activity Noted
In addition to explosions, three seismically recorded rockfalls have been reported. These events, common with active volcanoes like Semeru, suggest potential instability in the surrounding area. While rockfalls, ash, and lava represent volcanic hazards, rockfalls currently offer a reprieve. Travelers should be aware of potential disruptions to air and ground travel, as well as the health risks associated with volcanic ash.
Travel Warning in Place for East Java, Indonesia
Due to the ongoing eruptions, travel advisories are in effect for both local residents and visitors. Travel within areas affected by ash and eruptions in East Java is restricted. The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG), Indonesia’s official volcanic hazard agency, advises caution and encourages individuals to follow the volcano’s activity closely.
Tourists planning to visit Semeru and nearby areas should consult official government websites and social media channels for the latest information regarding flights, road access, and health precautions. The Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG) provides continuous updates on volcanic activity and related hazards.
Local Safety Measures and Precautions
Local governments and tour operators in East Java have implemented safety measures to minimize risks for residents and visitors. Visitors should be prepared for disruptions caused by the volcanic eruption and resulting smoke clouds. It is recommended to avoid smoke clouds and exposure to volcanic ash, remain indoors when possible, and wear protective gear if smoke exposure is likely.
Monitoring systems have been implemented at local transport terminals and potentially at the Malang and Surabaya airports to track the eruption. Travelers should check with transport and air travel operators for updates on potential disruptions caused by the eruption or ashy weather conditions.
Traveling During Volcanic Eruptions
Semeru, an active volcano in East Java, Indonesia, presents both dangers and scenic beauty. While eruptions pose risks to tourism, understanding safety regulations and staying informed are crucial for anyone considering a visit to the volcano or other volcanoes in East Java. Indonesia is known for its numerous active volcanoes, requiring careful consideration of safety concerns.
The eruption of the Semeru volcano in East Java, Indonesia, has led to travel restrictions for locals and visitors.
