Mount Semeru Eruption in Indonesia Triggers Evacuations
Indonesia's Mount Semeru, the highest peak on the island of Java, has erupted, blanketing multiple communities with volcanic ash, prompting evacuations and causing officials to elevate the warning to the highest level.
The mountain in East Java province unleashed searing clouds of fiery ash and a mixture of rock, lava and gas that moved up to 4 miles down its sides multiple times from noon to dusk, while a thick column of fiery clouds rose 1.2 miles into the air, according to Indonesia’s Geology Agency.
The eruptions that occurred throughout the day forced authorities to raise the volcano’s alert level on two occasions, from the level three to the highest, the agency said. No deaths or injuries have been announced.
More than 300 residents in the three villages most at risk in the area of Lumajang region were relocated to government shelters, as mentioned by a spokesperson for the national emergency management body.
He stated that heightened volcanic movements of the volcano on Wednesday afternoon prompted authorities to widen the hazard area to 8km from the summit. People were urged to stay clear from an zone along the Kobokan River, which is the route of the molten rock stream, as scorching gases moved down the volcano's sides.
Videos on social media showed a dense cloud of ash moving through a forested valley to a waterway beneath a bridge. Residents, some with faces smeared with ash and rain, fled to makeshift refuges or departed for alternative secure locations.
Regional news outlets indicated that authorities were struggling to save about 178 people stranded on the 12,060-foot peak at the Ranu Kumbolo monitoring post. The group comprised 137 climbers, 15 porters, seven escorts and six travel representatives, according to an official with the national park.
“They are currently safe at Ranu Kumbolo monitoring post,” a spokesperson stated in a recorded message. He said the station was situated 4.5km from the crater on the northern slope of the volcano, which is outside the trajectory of the hot cloud flow that was seen traveling to the southeast direction. Inclement conditions and rain required the team to remain overnight there, he explained.
The volcano, also known as Great Mountain, has erupted numerous times in the last two centuries. However, as is the situation with numerous of the 129 live volcanoes in Indonesia, thousands of people continue to reside on its fertile slopes.
The mountain's last major eruption was in December 2021, when 51 individuals were killed and hundreds others were burned and villages were buried in layers of mud. The event led to the evacuation of over ten thousand residents from their houses.
The country, an island chain of more than 280 million inhabitants, is located along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is prone to seismic events and volcanism.
