Mount Mahameru Outburst in the Southeast Asian nation Prompts Emergency Relocations
The nation's Mount Semeru, the highest peak on Java island, has erupted, covering 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 released searing clouds of hot ash and a combination of stone, molten rock, and gases that moved up to 7km down its slopes several times from noon to evening, while a thick column of fiery clouds rose 2km into the sky, according to the nation's geological authority.
The outbursts that unfolded throughout the day forced authorities to increase the mountain's warning status on two occasions, from the level three to the top level, the agency reported. No casualties have been reported.
More than 300 residents in the three communities most at risk in the area of Lumajang were evacuated to official safe havens, according to a spokesperson for the national emergency management body.
He stated that increased activity of the mountain on Wednesday afternoon led officials to widen the danger zone to 8km from the crater. People were urged to keep away from an zone along the Besuk Kobokan River, which is the route of the molten rock stream, as scorching gases flowed down the volcano's sides.
Footage on online platforms showed a dense cloud of ash moving through a wooded ravine to a river beneath a overpass. Locals, some with faces covered with volcanic dust and rain, escaped to temporary shelters or departed for other safe areas.
Regional news outlets indicated that authorities were facing challenges to rescue about 178 individuals trapped on the 12,060-foot mountain at the Ranu Kumbolo monitoring post. The group comprised 137 hikers, 15 porters, seven escorts and six travel representatives, according to an official with the protected area.
“They are currently safe at Ranu Kumbolo monitoring post,” a spokesperson stated in a recorded message. He said the station was located 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 southeast direction. Bad weather and precipitation required the team to remain overnight there, he added.
Semeru, also called Great Mountain, has burst numerous times in the last two centuries. However, as is the situation with many of the 129 live volcanoes in the archipelago, thousands of residents still to reside on its fertile slopes.
The mountain's previous significant explosion was in late 2021, when 51 individuals were lost their lives and several hundred others were injured and villages were submerged in layers of mud. The event forced the evacuation of over ten thousand people from their homes.
The country, an island chain of more than 280 million inhabitants, sits along the Pacific “ring of fire”, a curved series of fault lines, and is prone to earthquakes and volcanic activity.
