Volcano Mahameru Outburst in the Southeast Asian nation Triggers Evacuations
The nation's Mount Semeru, the highest peak on Java island, has exploded, blanketing several villages with falling ash, leading to evacuations and causing officials to elevate the warning to the highest level.
The mountain in East Java province released blistering plumes of hot ash and a combination of stone, molten rock, and gases that travelled up to 4 miles down its sides several times from noon to evening, while a thick column of hot clouds rose 1.2 miles into the air, according to Indonesia’s Geology Agency.
The eruptions that unfolded throughout the day forced authorities to increase the mountain's warning status twice, from the third-highest level to the top level, the authority reported. No deaths or injuries have been announced.
More than 300 residents in the three villages most endangered in the district of Lumajang were evacuated to official safe havens, according to a spokesperson for the national disaster mitigation agency.
He stated that increased activity of the volcano on Wednesday afternoon prompted authorities to expand the hazard area to 8km from the summit. People were advised to keep away from an area along the Besuk Kobokan River, which is the path of the molten rock stream, as searing gas moved down Semeru’s slopes.
Footage on online platforms showed a thick plume of volcanic dust moving through a wooded ravine to a river beneath a overpass. Residents, some with faces smeared with ash and water, escaped to makeshift refuges or departed for alternative secure locations.
Local media indicated that emergency teams were struggling to save about 178 individuals trapped on the 3,676-metre peak at the Ranu Kumbolo observation station. The group comprised 137 climbers, 15 carriers, seven guides and six tourism officials, according to an official with the protected area.
“They are currently safe at Ranu Kumbolo monitoring post,” an official stated in a recorded message. He said the station was located 4.5km from the crater on the northern slope of the volcano, which is not in the path of the fiery cloud movement that was observed traveling to the southeast direction. Bad weather and precipitation forced the group to remain overnight there, he added.
The volcano, also known as Great Mountain, has burst numerous times in the last two centuries. However, as is the situation with many of the 129 active volcanoes in the archipelago, tens of thousands of people continue to live on its fertile slopes.
Semeru’s last major eruption was in December 2021, when 51 people were killed and hundreds others were burned and villages were buried in layers of mud. The eruption forced the evacuation of over ten thousand people from their homes.
Indonesia, an island chain of over 280 million inhabitants, is located along the Pacific “ring of fire”, a curved series of tectonic boundaries, and is susceptible to earthquakes and volcanism.
