The nation's Semeru volcano, the highest peak on the island of Java, has exploded, blanketing several villages with volcanic ash, prompting evacuations and leading authorities to raise the warning to the maximum level.
The volcano in the province of East Java released searing clouds of hot ash and a mixture of stone, molten rock, and gases that travelled up to 4 miles down its slopes multiple times from midday to dusk, while a dense plume of hot clouds rose 1.2 miles into the air, as stated by the nation's geological authority.
The outbursts that unfolded throughout the day forced officials to increase the mountain's warning status twice, from the third-highest level to the highest, the agency said. No casualties have been announced.
Over three hundred residents in the three communities most endangered in the area of Lumajang region were evacuated to official safe havens, according to a spokesperson for the national emergency management body.
He said that increased activity of the volcano on the afternoon of Wednesday led authorities to widen the hazard area to 5 miles from the summit. People were urged to keep away from an zone along the Kobokan River, which is the route of the molten rock stream, as searing gas flowed down Semeru’s slopes.
Footage on social media showed a thick plume of volcanic dust moving through a forested valley to a waterway beneath a bridge. Residents, some with faces smeared with ash 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 individuals stranded on the 12,060-foot mountain at the Ranu Kumbolo observation station. The party comprised 137 hikers, 15 porters, seven escorts and six tourism officials, according to an spokesperson with the national park.
“They are currently safe at Ranu Kumbolo monitoring post,” a spokesperson stated in a recorded message. He noted the station was situated 2.8 miles from the crater on the north side of the mountain, which is not in the path of the fiery cloud movement that was seen moving to the southeast direction. Inclement conditions and precipitation required the group to remain overnight there, he added.
The volcano, also known as Great Mountain, has burst many occasions in the last two centuries. However, as is the case with numerous of the 129 live volcanoes in Indonesia, thousands of residents continue to reside on its fertile slopes.
Semeru’s previous significant explosion was in December 2021, when 51 individuals were killed and several hundred others were injured and villages were buried in layers of mud. The eruption forced the evacuation of more than 10,000 residents from their houses.
The country, an archipelago of more than 280 million people, sits along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is susceptible to earthquakes and volcanism.
