Table of Contents
IndonesiaS Lewotobi twin volcanoes in East Flores,east Nusa Tenggara province,erupted on Friday,September 19,2024,prompting authorities to issue warnings and advise residents to stay clear of the area. The eruption produced a meaningful seismic event and raised concerns about potential lava floods.
Eruption Details and Seismic Activity
The eruption was recorded by a seismogram showing a maximum amplitude of 47.3 millimeters and lasting approximately 17 minutes and 7 seconds, according to a statement from the Volcanological and Geological Hazard Mitigation Center (PVMBG) https://magma.esdm.go.id/doc/info_gunung/LEWOTOBI-20240919-1615.pdf. A strong roar was heard at the PGA Lewotobi observation post during the eruption.
Evacuation and Safety Recommendations
Emanuel, head of the PVMBG, has urged the public to refrain from any activities within a 6-kilometer radius of the eruption center. Residents are also advised to remain vigilant for potential lahar (lava floods) in rivers originating from Mount Lewotobi, particularly during periods of heavy rainfall. Specifically, authorities have warned communities in dulipali, desert, Nobo, Nobilen, Klatanlo, Hokeng Jaya, Boru, and Nawakote to be prepared for potential lahar flows.
Understanding Volcanic Hazards: Lahar
Lahar, or volcanic mudflows, are a hazardous secondary hazard associated with volcanic eruptions. They form when volcanic ash and debris mix with water (from rainfall, melting snow, or crater lakes) creating fast-moving, destructive flows that can travel long distances down river valleys. The steep slopes of Lewotobi increase the risk of lahar formation during and after eruptions.
background on Lewotobi
Lewotobi is a twin volcano comprised of lewotobi Laki-laki (male) and lewotobi Perempuan (female) peaks. The volcano is part of the Sunda Arc, a highly volcanically active region formed by the subduction of the Indo-Australian Plate beneath the Eurasian Plate. Indonesia, situated within this arc, has more active volcanoes than any other country in the world.
key Takeaways:
* Lewotobi twin volcanoes in East Flores, Indonesia erupted on September 19, 2024.
* A 6-kilometer exclusion zone has been established around the eruption center.
* residents near the volcano are warned about the risk of lahar (lava floods),especially during rainfall.
* The eruption was recorded with a maximum amplitude of 47.3 millimeters and a duration of 17 minutes 7 seconds.
Indonesia’s volcanological authorities continue to monitor Lewotobi closely, and further updates will be provided as the situation evolves. Residents are encouraged to stay informed through official channels and heed all warnings issued by the PVMBG.
