TEMPO.CO, Lumajang - Mount Semeru reportedly erupted again on Wednesday morning, February 12, 2025. The eruption column observed was 1,000 meters above the summit (approximately 4,676 meters above sea level).
The Semeru Volcano Observation Post (PGA) recorded the eruption on Wednesday morning at around 05:38 AM local time. The observed ash column appeared white to gray with moderate intensity heading north. PGA Semeru Post officer, Liswanto, stated that the eruption was still ongoing at the time of the report.
Two hours later, at 08:11 AM, another eruption was reported, but no visual eruption was observed. This eruption was recorded on the seismograph with a maximum amplitude of 22 mm and a duration of 120 seconds.
In the last 24 hours until early Wednesday, the seismograph at the PGA Semeru Post located in Mount Sawur, Sumber Wuluh Village, Candipuro District, Lumajang Regency, recorded a number of seismic activities. There were 55 times of eruption seismic activity recorded with amplitudes of 10-23 mm and a duration of 49-162 seconds.
Three rockfall seismic activities were also recorded with amplitudes of 2-6 mm and a duration of 32-74 seconds, four times of blast seismic activities with amplitudes of 2 mm and a duration of 29-52 seconds; two times of harmonic seismic activities with amplitudes of 2-3 mm and a duration of 360-402 seconds; two times of distant tectonic earthquakes with amplitudes of 20-24 mm and S-P 15-27 seconds and a duration of 42-82 seconds.
Liswanto stated that the activity status of Mount Semeru remains at level II (caution). At this level, the Center for Volcanology and Geological Disaster Mitigation (PVMBG) issued several recommendations, including not engaging in any activities in the southeastern sector along Besuk Kobokan, up to 8 kilometers from the summit (eruption center).
Outside that range, the public is asked not to engage in activities within 500 meters from the riverbank along Besuk Kobokan due to the potential impact of expanding hot clouds and lahars up to a distance of 13 kilometers from the summit.
Furthermore, they should not engage in activities within a 3-kilometer radius from the crater/summit of Mount Semeru due to the risk of rock projectiles.
The public is also urged to be cautious of potential pyroclastic flow, lava flow, and lahars along the river valley originating from Mount Semeru, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat, as well as potential lahars in the small rivers that are tributaries of Besuk Kobokan.
