Mount Semeru Eruption in Indonesia Triggers Evacuations
Indonesia's Mount Semeru, the tallest summit on Java island, has exploded, blanketing multiple communities with volcanic ash, leading to evacuations and causing officials to elevate the warning to the highest level.
The mountain in the province of East Java unleashed blistering plumes of hot ash and a mixture of stone, molten rock, and gases that travelled up to 4 miles down its sides several times from noon to dusk, while a thick column of fiery clouds rose 1.2 miles into the air, as stated by the nation's geological authority.
The outbursts that unfolded throughout the day compelled authorities to increase the volcano’s alert level twice, from the level three to the highest, the agency said. No casualties have been announced.
Over three hundred inhabitants in the three villages most at risk in the area of Lumajang region were relocated to official safe havens, according to a representative for the national emergency management body.
He said that heightened volcanic movements of the mountain on the afternoon of Wednesday led officials to widen the hazard area to 8km from the crater. Residents were advised to keep away from an zone along the Kobokan River, which is the route of the lava flow, as scorching gases flowed down Semeru’s slopes.
Videos on social media displayed a thick plume of volcanic dust 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 departed for alternative secure locations.
Regional news outlets reported that emergency teams were struggling to save about 178 individuals trapped on the 12,060-foot peak at the Ranu Kumbolo observation station. The group included 137 hikers, 15 porters, seven guides and six tourism officials, according to an official with the national park.
“They are currently safe at Ranu Kumbolo monitoring post,” an official said in a recorded message. He said the post was situated 4.5km from the summit 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. Bad weather and rain forced the team to remain overnight there, he added.
The volcano, also known as Mahameru, has burst numerous times in the past 200 years. However, as is the case with many of the 129 live volcanoes in Indonesia, thousands of people still to live on its fertile slopes.
The mountain's last major eruption was in late 2021, when 51 people were killed and several hundred more were injured and villages were submerged in thick mud. The eruption led to the relocation of more than 10,000 people from their houses.
The country, an island chain of over 280 million inhabitants, sits along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is prone to seismic events and volcanism.
