Mount Semeru in East Java erupted again on Sunday, July 7, 2024, at 09:34 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 62 times.

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

The ash column was observed to be white to gray with thick intensity towards the north. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 115 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity on July 7, 2024, from 00:00 to 06:00 WIB showed 38 eruption quakes with amplitudes of 14-23 millimeters and durations of 64-142 seconds.

Furthermore, there were 7 rockfall quakes with amplitudes of 3-12 mm and durations of 58-105 seconds, and 2 emission quakes with amplitudes of 6-8 millimeters and durations of 45-55 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 buffer zone) along Besuk Kobokan due to the potential for pyroclastic flow and lahar flows extending up to 17 kilometers from the peak.

During 2024, MAGMA Indonesia has recorded 1,494 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 659 recorded events.
