Mount Mahameru Outburst in the Southeast Asian nation Triggers Emergency Relocations
Indonesia's Semeru volcano, the highest peak on Java island, has erupted, covering several villages with volcanic ash, leading to evacuations and leading authorities to raise the alert to the highest level.
The mountain in East Java province released blistering plumes of fiery ash and a mixture of rock, lava and gas that moved up to 4 miles down its slopes multiple times from noon to evening, while a thick column of hot clouds rose 2km into the sky, according to the nation's geological authority.
The eruptions that unfolded throughout the day compelled officials to increase the volcano’s alert level twice, from the third-highest level to the top level, the authority reported. No casualties have been announced.
More than 300 residents in the three communities most endangered in the district of Lumajang were evacuated to official safe havens, according to a spokesperson for the national disaster mitigation agency.
He said that increased activity of the volcano on the afternoon of Wednesday led officials to widen the hazard area to 8km from the summit. Residents were advised to keep away from an zone along the Kobokan River, which is the route of the lava flow, as scorching gases moved down the volcano's sides.
Footage on online platforms displayed a dense cloud of ash sweeping through a wooded ravine to a waterway beneath a overpass. Locals, some with faces smeared with volcanic dust and rain, escaped to temporary shelters or left for alternative secure locations.
Regional news outlets indicated that emergency teams were struggling to save about 178 people stranded on the 12,060-foot peak at the Ranu Kumbolo monitoring post. The party comprised 137 climbers, 15 porters, seven escorts and six travel representatives, according to an spokesperson with the protected area.
“They are currently safe at the Ranu Kumbolo station,” an official stated in a recorded message. He noted the post was situated 2.8 miles from the crater on the northern slope of the volcano, which is not in the path of the fiery cloud movement that was seen moving to the south-southeast. Inclement conditions and rain forced the team to spend the night there, he added.
Semeru, also called Mahameru, has erupted numerous times in the last two centuries. However, as is the situation with numerous of the 129 active volcanoes in the archipelago, thousands of people continue to live on its productive highlands.
Semeru’s last major eruption was in late 2021, when 51 individuals were killed and hundreds more were burned and settlements were submerged in thick mud. The eruption led to the relocation of more than 10,000 people from their houses.
Indonesia, an archipelago of more than 280 million inhabitants, sits along the Pacific seismic belt, a curved series of tectonic boundaries, and is susceptible to earthquakes and volcanism.
