Mount Mahameru Eruption in Indonesia Triggers Evacuations
The nation's Mount Semeru, the tallest summit on the island of Java, has exploded, covering several villages with volcanic ash, prompting evacuations and causing officials to elevate the alert to the highest level.
The volcano in the province of East Java unleashed searing clouds of hot ash and a combination of stone, molten rock, and gases that moved up to 4 miles down its sides multiple times from midday to evening, while a dense plume of hot clouds rose 2km into the sky, as stated by Indonesia’s Geology Agency.
The eruptions that unfolded throughout the day forced officials to raise the volcano’s alert level twice, from the third-highest level to the top level, the authority said. No deaths or injuries have been announced.
Over three hundred residents in the three villages most endangered in the district of Lumajang were evacuated to official safe havens, according to a spokesperson for the national disaster mitigation agency.
He stated that increased activity of the volcano on the afternoon of Wednesday led officials to expand the danger zone to 8km from the crater. People were advised to stay clear from an zone along the Besuk Kobokan River, which is the path of the lava flow, as searing gas moved down the volcano's sides.
Footage on online platforms showed a thick plume of ash moving through a forested valley to a river beneath a bridge. Residents, some with faces covered with volcanic dust and rain, fled to makeshift refuges or departed for other safe areas.
Local media indicated that authorities were facing challenges to save about 178 people trapped on the 3,676-metre peak at the Ranu Kumbolo observation station. The party included 137 hikers, 15 porters, seven guides and six tourism officials, according to an spokesperson with the national park.
“They are currently safe at the Ranu Kumbolo station,” a spokesperson said in a recorded message. He said the station was situated 2.8 miles from the summit on the north side of the volcano, which is not in the path of the hot cloud flow that was seen traveling to the southeast direction. Inclement conditions and precipitation forced the group to remain overnight there, he added.
The volcano, also called Mahameru, has erupted many occasions in the last two centuries. Still, as is the situation with many of the 129 live volcanoes in Indonesia, tens of thousands of people still to live on its productive highlands.
The mountain's previous significant explosion was in late 2021, when 51 individuals were lost their lives and hundreds more were burned and settlements were buried in thick mud. The event forced the relocation of over ten thousand residents from their houses.
Indonesia, an island chain of more than 280 million inhabitants, sits along the Pacific “ring of fire”, a curved series of tectonic boundaries, and is prone to seismic events and volcanic activity.
