Thursday Morning, Mount Semeru Eruption And Residents Of 3 KM Radius Asked To Be Alert

"There was an eruption of Mount Semeru on Thursday, March 6, 2025, at 07.06 WIB. The height of the eruption column was observed about 1,100 meters above the peak or 4,776 meters above sea level," said the officer of the Mount Semeru Observation Post, Liswanto, quoted by ANTARA.

The ash column was observed to be white to gray with moderate intensity to the southwest. When the report was made by officers, the eruption was still ongoing.

The highest mountain on the island of Java erupted again at 07.20 WIB with an eruptive column height lower than before, which was 200 meters above the peak or 3,876 meters above sea level.

The ash column was observed to be white to gray with moderate intensity to the southwest. When the report was made, the eruption was still ongoing.

Based on the officer's report, Mount Semeru was recorded to have experienced five eruptions on Thursday morning with the first eruption occurring at 01.56 WIB with an eruption column height observed 500 meters above the peak.

The ash column was observed to be white to gray with thick intensity to the southwest. This eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 122 seconds.

Then the eruption occurred again at 06.14 WIB and 06.27 WIB with visual eruptions not being observed, then at 07.06 WIB and 07.20 WIB.

Liswanto said Mount Semeru is still on alert status, so the Center for Volcanology and Geological Hazard Mitigation (PVMBG) provides a number of recommendations, namely that people are prohibited from carrying out any activity in the southeast sector along Besuk Kobokan as far as eight kilometers from the summit (the center of the eruption).

Kemudian di luar jarak tersebut, masyarakat tidak boleh melakukan aktivitas pada jarak 500 meter dari tepi sungai (sempadan sungai) di sepanjang Besuk Kobokan, karena berpotensi terlanda perluasan awan panas dan aliran lahar hingga jarak 13 kilometer dari puncak.

In addition, he said, the public also needs to be aware of the potential for hot clouds, lava avalanches, and rain lava along rivers/valleys that originate at the top of Mount Semeru, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat, as well as the potential for lava in small rivers that are tributaries from Besuk Kobokan.
