Mount Semeru in East Java erupted again on Sunday, May 5, 2024, at 8:22 PM WIB. In the last week, Mount Semeru has erupted 17 times.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column height was observed to be approximately 700 meters above the peak or 4,376 meters above sea level.

The ash column was observed to be gray with thick intensity towards the northwest. The eruption was recorded on a seismograph with a maximum amplitude of 23 millimeters and a duration of 134 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on May 5, 2024, from 12:00 PM to 6:00 PM WIB showed 8 eruption quakes with amplitudes of 10-22 millimeters and durations of 45-128 seconds. There were also 2 local tectonic quakes with amplitudes of 15-30 millimeters, s-p 4.9-5.5 seconds, and durations of 28-31 seconds.

PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the peak (eruption center). Outside this distance, people should not engage in activities within 500 meters of the riverbank (river boundaries) along Besuk Kobokan due to the potential for hot cloud expansion and lava flows up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 631 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 213 recorded events.
