Mount Mahameru Eruption in Indonesia Prompts Evacuations
The nation's Semeru volcano, the highest peak on the island of Java, has erupted, covering several villages with volcanic ash, prompting evacuations and causing officials to elevate the alert to the maximum level.
The mountain in East Java province unleashed searing clouds of fiery ash and a mixture of rock, lava and gas that travelled up to 4 miles down its sides several times from midday to dusk, while a dense plume of hot clouds rose 1.2 miles into the sky, according to the nation's geological authority.
The eruptions that occurred throughout the day compelled officials to increase the volcano’s alert level on two occasions, from the level three to the top level, the agency reported. No casualties have been reported.
Over three hundred inhabitants in the three communities most at risk in the district of Lumajang were evacuated to government shelters, according to a representative for the national disaster mitigation agency.
He stated that heightened volcanic movements of the mountain on the afternoon of Wednesday prompted authorities to widen the hazard area to 8km from the summit. Residents were advised to stay clear from an zone along the Kobokan River, which is the route of the molten rock stream, as searing gas flowed down Semeru’s slopes.
Videos on online platforms showed a dense cloud of volcanic dust moving through a forested valley to a waterway beneath a bridge. Locals, some with faces smeared with volcanic dust and water, fled to temporary shelters or left for other safe areas.
Local media indicated that emergency teams were facing challenges to rescue about 178 individuals stranded on the 12,060-foot mountain at the Ranu Kumbolo observation station. The party included 137 hikers, 15 carriers, seven escorts and six travel representatives, according to an spokesperson with the protected area.
“They are currently safe at Ranu Kumbolo monitoring post,” a spokesperson said in a video statement. He said the station was situated 2.8 miles from the summit on the north side of the volcano, which is not in the path of the fiery cloud movement that was seen traveling to the south-southeast. Bad weather and precipitation forced the group to remain overnight there, he explained.
The volcano, also called Great Mountain, has burst numerous times in the last two centuries. Still, as is the situation with numerous of the 129 active volcanoes in the archipelago, tens of thousands of residents still to reside on its productive highlands.
Semeru’s previous significant explosion was in late 2021, when 51 people were killed and several hundred others were burned and settlements were buried in layers of mud. The event led to the evacuation of more than 10,000 residents from their houses.
Indonesia, an archipelago of more than 280 million inhabitants, is located along the Pacific seismic belt, a horseshoe-shaped series of tectonic boundaries, and is susceptible to earthquakes and volcanic activity.
