Mount Semeru in East Java erupted again on Sunday, July 7, 2024, at 2:31 PM WIB. In the last week, Mount Semeru has erupted 63 times.

Based on eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the visual eruption was not observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 millimeters and a duration of 102 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Semeru's activity level is at Level III (Alert). Observations of seismic activity from 6:00 AM to 12:00 PM WIB on July 7, 2024, showed 40 eruption quakes with amplitudes of 10-22 millimeters and durations of 64-116 seconds.

Furthermore, there were 3 rockfall quakes with amplitudes of 4-8 mm and durations of 68-75 seconds, and 1 distant tectonic quake with an amplitude of 15 millimeters, an S-P time of 16 seconds, and a duration of 57 seconds.

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

During 2024, MAGMA Indonesia has recorded 1,496 volcanic eruptions/eruptions throughout Indonesia. Mount Semeru in East Java has experienced the most eruptions, with 660 occurrences.
