Mount Semeru Outburst in the Southeast Asian nation Prompts Evacuations
The nation's Semeru volcano, the tallest summit on Java island, has erupted, covering several villages with volcanic ash, leading to evacuations and leading authorities to raise the warning to the maximum level.
The volcano in the province of East Java unleashed blistering plumes of fiery ash and a mixture of rock, lava and gas that travelled up to 4 miles down its sides several times from noon to dusk, while a dense plume of hot clouds rose 2km into the sky, according to the nation's geological authority.
The eruptions that occurred throughout the day forced officials to raise the volcano’s alert level on two occasions, from the third-highest level to the highest, the authority said. No deaths or injuries have been reported.
Over three hundred inhabitants in the three villages most endangered in the area of Lumajang region were relocated to official safe havens, as mentioned by a representative for the national disaster mitigation agency.
He said that increased activity of the mountain on the afternoon of Wednesday led officials to widen the hazard area to 5 miles from the crater. Residents were advised to keep away from an area along the Besuk Kobokan River, which is the path of the lava flow, as scorching gases flowed down Semeru’s slopes.
Videos on online platforms displayed a thick plume of volcanic dust sweeping through a forested valley to a river beneath a bridge. Locals, some with faces smeared with volcanic dust and water, escaped to temporary shelters or departed for alternative secure locations.
Regional news outlets reported that authorities were struggling to save about 178 individuals stranded on the 12,060-foot peak at the Ranu Kumbolo observation station. The party included 137 climbers, 15 porters, seven guides and six travel representatives, according to an official with the protected area.
“They remain secure at the Ranu Kumbolo station,” a spokesperson 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 seen traveling to the south-southeast. Inclement conditions and precipitation forced the group 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 the archipelago, tens of thousands of people still to live on its fertile slopes.
The mountain's previous significant explosion was in late 2021, when 51 people were killed and several hundred others were injured and settlements were submerged in thick mud. The eruption forced the evacuation of over ten thousand residents from their homes.
Indonesia, an archipelago of more than 280 million people, is located along the Pacific seismic belt, a horseshoe-shaped series of fault lines, and is susceptible to seismic events and volcanic activity.
