Mount Semeru in East Java erupted again on Sunday, March 3, 2024, at 00:13 WIB (Western Indonesian Time). In the last week, Mount Semeru has erupted 23 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 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 March 3, 2024, from 18:00 to 23:59 WIB, showed 20 eruption quakes with amplitudes of 10-22 millimeters and durations of 46-218 seconds.

Furthermore, there were 5 puffing quakes with amplitudes of 4-6 millimeters and durations of 50-66 seconds, and 5 harmonic tremors with amplitudes of 6-15 millimeters and durations of 197-2149 seconds.

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

During 2024, MAGMA Indonesia has recorded 328 volcanic eruptions/eruptions throughout Indonesia. Mount Marapi in West Sumatra experienced the most eruptions (98 times), while Mount Semeru erupted 89 times.
