Volcano Semeru Outburst in the Southeast Asian nation Triggers Evacuations
Indonesia's Mount Semeru, the tallest summit on Java island, has erupted, covering multiple communities with volcanic ash, leading to evacuations and causing officials to elevate the alert to the maximum level.
The volcano in the province of East Java unleashed searing clouds of hot ash and a mixture of stone, molten rock, and gases that moved up to 7km down its slopes multiple times from noon to dusk, while a thick column of fiery clouds rose 1.2 miles into the sky, as stated by the nation's geological authority.
The eruptions that occurred throughout the day compelled officials to increase the mountain's warning status on two occasions, 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 communities most endangered in the area of Lumajang were evacuated to government shelters, as mentioned by a spokesperson for the national disaster mitigation agency.
He stated that heightened volcanic movements of the volcano on the afternoon of Wednesday prompted authorities to widen the hazard area to 5 miles from the summit. People were urged to stay clear from an zone along the Kobokan River, which is the route of the lava flow, as scorching gases flowed down the volcano's sides.
Videos on social media displayed a thick plume of volcanic dust moving through a wooded ravine to a waterway beneath a bridge. Residents, some with faces smeared with ash and water, fled to makeshift refuges or departed for other safe areas.
Regional news outlets reported that authorities were struggling to save about 178 individuals stranded on the 12,060-foot mountain at the Ranu Kumbolo observation station. The party comprised 137 hikers, 15 porters, seven guides and six travel representatives, according to an spokesperson with the protected area.
“They are currently safe at Ranu Kumbolo monitoring post,” an official stated in a recorded message. He noted the post was located 4.5km from the crater on the northern slope of the mountain, which is not in the path of the hot cloud flow that was seen traveling to the south-southeast. Inclement conditions and precipitation required the group to spend the night there, he added.
The volcano, also called Great Mountain, has erupted many occasions in the last two centuries. Still, as is the case with many of the 129 live volcanoes in Indonesia, tens of thousands of residents still to reside on its fertile slopes.
The mountain's last major eruption was in late 2021, when 51 individuals were killed and hundreds more were injured and villages were submerged in layers of mud. The event led to the relocation of over ten thousand residents from their houses.
Indonesia, an island chain of more than 280 million people, sits along the Pacific seismic belt, a horseshoe-shaped series of tectonic boundaries, and is prone to earthquakes and volcanic activity.
