Volcano Mahameru Outburst in Indonesia Triggers Evacuations
Indonesia's Mount Semeru, the tallest summit on Java island, has erupted, covering several villages with falling ash, leading to evacuations and causing officials to elevate the alert to the highest level.
The mountain in East Java province released blistering plumes of fiery ash and a combination of stone, molten rock, and gases that travelled up to 7km down its slopes several times from noon to dusk, while a dense plume of hot clouds rose 1.2 miles into the sky, as stated by the nation's geological authority.
The outbursts that unfolded throughout the day compelled officials to increase the mountain's warning status on two occasions, from the level three to the highest, the agency said. No casualties have been reported.
Over three hundred residents in the three villages most endangered in the district of Lumajang were relocated to government shelters, as mentioned by a spokesperson for the national emergency management body.
He said that heightened volcanic movements of the mountain on the afternoon of Wednesday prompted officials to widen the hazard area to 8km from the crater. People were urged to stay clear from an area along the Besuk Kobokan River, which is the route of the molten rock stream, as scorching gases flowed down Semeru’s slopes.
Footage on social media showed a dense cloud of ash moving through a wooded ravine to a river beneath a overpass. Locals, some with faces covered with volcanic dust and water, escaped to makeshift refuges or left for other safe areas.
Local media indicated that authorities were facing challenges to rescue about 178 people trapped on the 3,676-metre mountain at the Ranu Kumbolo observation station. The group included 137 hikers, 15 porters, seven guides and six travel representatives, according to an spokesperson with the protected area.
“They remain secure at the Ranu Kumbolo station,” a spokesperson stated in a video statement. He said the post was located 4.5km from the crater on the north side of the mountain, which is outside the trajectory of the hot cloud flow that was observed traveling to the south-southeast. Inclement conditions and rain forced the team to remain overnight there, he added.
Semeru, also known as Great Mountain, has burst many occasions in the last two centuries. Still, as is the situation with many of the 129 active volcanoes in Indonesia, tens of thousands of residents continue to live on its productive highlands.
Semeru’s previous significant explosion was in late 2021, when 51 individuals were killed and several hundred more were burned and settlements were submerged in layers of mud. The event forced the relocation of more than 10,000 residents from their homes.
Indonesia, an island chain of more than 280 million people, is located along the Pacific “ring of fire”, a horseshoe-shaped series of fault lines, and is susceptible to seismic events and volcanism.
