Mount Semeru Eruption in Indonesia Triggers Emergency Relocations
The nation's Semeru volcano, the highest peak on Java island, has exploded, covering several villages with falling ash, leading to evacuations and causing officials to elevate the alert to the maximum level.
The mountain in East Java province released searing clouds of hot ash and a mixture of stone, molten rock, and gases that moved up to 7km down its slopes multiple times from noon to evening, while a thick column of hot clouds rose 1.2 miles into the air, according to the nation's geological authority.
The outbursts that occurred throughout the day forced authorities to increase the mountain's warning status on two occasions, from the third-highest level to the top level, the authority said. No casualties have been reported.
Over three hundred inhabitants in the three villages most at risk in the area of Lumajang were evacuated to official safe havens, according to a representative for the national disaster mitigation agency.
He stated that heightened volcanic movements of the volcano on Wednesday afternoon led officials to widen the danger zone to 8km from the summit. People were advised to stay clear from an zone along the Kobokan River, which is the route of the lava flow, as scorching gases moved down the volcano's sides.
Footage on online platforms showed a dense cloud of volcanic dust moving through a wooded ravine to a waterway beneath a bridge. Locals, some with faces covered with volcanic dust and rain, fled to makeshift refuges or left for other safe areas.
Local media indicated that emergency teams were facing challenges to rescue about 178 individuals trapped on the 3,676-metre peak at the Ranu Kumbolo monitoring post. The party included 137 hikers, 15 porters, seven escorts and six tourism officials, according to an official with the national park.
“They remain secure at the Ranu Kumbolo station,” a spokesperson said in a video statement. He said the post was situated 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 moving to the southeast direction. Inclement conditions and precipitation required the team to spend the night there, he explained.
The volcano, also known as Great Mountain, has burst numerous times in the last two centuries. Still, as is the situation with many of the 129 active volcanoes in the archipelago, tens of thousands of residents still to live on its productive highlands.
The mountain's previous significant explosion was in late 2021, when 51 people were lost their lives and several hundred others were burned and villages were buried in layers of mud. The event led to the evacuation of more than 10,000 people from their houses.
The country, an island chain of over 280 million inhabitants, is located along the Pacific “ring of fire”, a curved series of fault lines, and is susceptible to earthquakes and volcanic activity.
