Mount Semeru Eruption in Indonesia Triggers Evacuations
The nation's Mount Semeru, the highest peak on the island of Java, has exploded, covering multiple communities with falling ash, leading to evacuations and leading authorities to raise the alert to the maximum level.
The mountain in the province of East Java unleashed searing clouds of hot ash and a combination of rock, lava and gas that moved up to 7km down its sides multiple times from midday to dusk, while a thick column of fiery clouds rose 2km into the sky, according to Indonesia’s Geology Agency.
The eruptions that occurred throughout the day compelled authorities to increase the volcano’s alert level on two occasions, from the third-highest level to the top level, the authority reported. No casualties have been announced.
More than 300 residents in the three villages most at risk in the district of Lumajang were relocated to government shelters, according to a representative for the national emergency management body.
He stated that increased activity of the volcano on the afternoon of Wednesday led authorities to expand the hazard area to 8km from the crater. People were advised to stay clear from an area along the Besuk Kobokan River, which is the route of the lava flow, as scorching gases flowed down the volcano's sides.
Footage on social media showed a dense cloud of volcanic dust moving through a wooded ravine to a river beneath a bridge. Residents, some with faces smeared with volcanic dust and rain, escaped to temporary shelters or left for alternative secure locations.
Local media reported that emergency teams were facing challenges to save about 178 people stranded on the 12,060-foot mountain at the Ranu Kumbolo monitoring post. The group included 137 climbers, 15 carriers, seven guides and six travel representatives, according to an spokesperson with the national park.
“They are currently safe at the Ranu Kumbolo station,” an official stated in a recorded message. He said the post was located 2.8 miles from the summit on the north side of the volcano, which is outside the trajectory of the fiery cloud movement that was observed traveling to the southeast direction. Inclement conditions and precipitation forced the team to spend the night there, he added.
Semeru, also called Mahameru, has erupted numerous times in the past 200 years. However, as is the case with numerous of the 129 live volcanoes in Indonesia, tens of thousands of residents continue to live on its productive highlands.
Semeru’s previous significant explosion was in December 2021, when 51 people were killed and several hundred others were burned and settlements were submerged in thick mud. The event forced the evacuation of more than 10,000 residents from their homes.
Indonesia, an island chain of more than 280 million inhabitants, sits along the Pacific seismic belt, a curved series of fault lines, and is prone to earthquakes and volcanic activity.
