TEMPO.CO, Lumajang - Indonesia's Mount Semeru reportedly erupted again on Monday morning, March 17, 2025. The height of the eruption column that occurred at 08:11 AM WIB (Western Indonesian Time) was observed to be approximately 1,000 meters above the summit (approximately 4,676 meters above sea level).
"The ash column was observed to be white to gray with moderate intensity towards the southeast. At the time of this report, the eruption is still ongoing," said Liswanto, an officer of the Semeru Volcano Monitoring Post (PGA) in his written report on Monday morning, March 17, 2025.
Based on observations from the PGA Post located at Mount Sawit, Sumber Wuluh Village, Candipuro District, Lumajang Regency, there were six eruptions on Monday morning. Meanwhile, based on observations in the last 24 hours until early Monday morning, several types of seismic activity were recorded. This includes 52 times of eruption earthquakes, 3 times of avalanche earthquakes, 19 times of gust earthquakes, 4 times of harmonic earthquakes, and 1 time of volcanic earthquake.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG), Geological Agency, stated that the activity level of Mount Semeru remains unchanged, still at level II or Caution. At this level, it is recommended not to carry out any activities in the southeastern sector along Besuk Kobokan, up to 8 kilometers from the summit (eruption center).
Outside of this distance, people should not carry out activities within 500 meters from the edge of the river (riverbanks) along Besuk Kobokan because of the potential for being hit by expanding hot clouds and lava flows up to 13 kilometers from the summit.
The Center for Volcanology and Geological Hazard Mitigation also recommends refraining from activities within a 3-kilometer radius from the crater/summit of Mount Semeru due to the risk of being hit by flying rocks (pyroclastic).
The public is also advised to be wary of the potential for hot clouds and lava flows along the river valleys that originate from Mount Semeru, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat, as well as the potential for lahars in small rivers that are tributaries of Besuk Kobokan.
