Three Indonesian Volcanoes Erupt Consecutively

Indonesia, a nation situated on the Pacific Ring of Fire, witnessed a series of volcanic eruptions on Tuesday night as three active volcanoes spewed ash and smoke. The Indonesian Geological Agency confirmed that Mount Ibu in North Maluku, Mount Lewotobi Laki-laki in East Nusa Tenggara, and Mount Semeru in East Java all experienced eruptions within a short period.

Mount Ibu, located in West Halmahera, recorded three separate eruptions within a few hours. The first eruption at 8:36 PM local time sent an ash column 700 meters above the peak, followed by another at 8:58 PM with a 500-meter ash column, and a third at 11:11 PM with a 600-meter ash column. The volcanic activity at Ibu is currently at Level II (Alert).

Meanwhile, Mount Lewotobi Laki-laki in East Flores erupted at 9:09 PM, ejecting a thick gray ash column 300 meters above its summit. Its seismic activity registered a maximum amplitude of 11 millimeters over 109 seconds, placing it at Level III (Standby). Concurrently, Mount Semeru in East Java erupted at 8:33 PM. Although the eruption was not visually observable due to fog, monitoring officers recorded seismic activity with a maximum amplitude of 22 millimeters over 235 seconds. Semeru is also at Level III (Standby).

The Geological Agency has issued specific recommendations for communities near Semeru. Residents are advised to avoid any activity within a 13-kilometer radius of the summit along Besuk Kobokan, and within 500 meters of riverbanks along Besuk Kobokan due to the potential for pyroclastic flows and lahars extending up to 17 kilometers. Additionally, a 5-kilometer exclusion zone around the crater or summit of Semeru is in place due to the risk of ejected incandescent rocks.
