Mount Mahameru Eruption in the Southeast Asian nation Prompts Evacuations
The nation's Mount Semeru, the tallest summit on the island of Java, has erupted, blanketing several villages with falling ash, prompting evacuations and causing officials to elevate the warning to the maximum level.
The volcano in the province of East Java released searing clouds of hot ash and a mixture of rock, lava and gas that moved up to 7km down its slopes multiple times from midday to evening, while a dense plume of hot clouds rose 2km into the air, as stated by Indonesia’s Geology Agency.
The eruptions that unfolded throughout the day forced authorities to increase the mountain's warning status 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 communities most at risk in the district of Lumajang were relocated to official safe havens, according to a representative for the national emergency management body.
He stated that increased activity of the mountain on Wednesday afternoon prompted authorities to widen the danger zone to 8km from the summit. Residents were urged to stay clear from an zone along the Kobokan River, which is the route of the lava flow, as scorching gases moved down Semeru’s slopes.
Videos on social media showed a dense cloud of volcanic dust sweeping through a wooded ravine to a river beneath a bridge. Residents, some with faces smeared with ash and rain, escaped to temporary shelters or left for alternative secure locations.
Regional news outlets reported that emergency teams were facing challenges to rescue about 178 people stranded on the 12,060-foot mountain at the Ranu Kumbolo observation station. The group included 137 climbers, 15 porters, seven escorts and six travel representatives, according to an official with the national park.
“They remain secure at the Ranu Kumbolo station,” a spokesperson stated in a recorded message. He said the station was situated 4.5km from the crater on the northern slope of the mountain, which is outside the trajectory of the fiery cloud movement that was observed moving to the southeast direction. Inclement conditions and precipitation required the team to spend the night there, he explained.
Semeru, also known as Mahameru, has burst numerous times in the past 200 years. Still, as is the situation with numerous of the 129 active volcanoes in the archipelago, tens of thousands of people continue to live on its productive highlands.
Semeru’s previous significant explosion was in late 2021, when 51 individuals were killed and several hundred others were burned and villages were submerged in thick mud. The eruption forced the relocation of over ten thousand people from their houses.
Indonesia, an island chain of more than 280 million people, sits along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is prone to earthquakes and volcanism.
