Volcano Semeru Outburst in Indonesia Triggers Evacuations
The nation's Mount Semeru, the highest peak on the island of Java, has exploded, covering several villages with volcanic ash, prompting evacuations and leading authorities to raise the warning to the highest level.
The volcano in the province of East Java released searing clouds of fiery ash and a mixture of rock, lava and gas that travelled up to 7km down its slopes multiple times from midday to dusk, while a thick column of fiery clouds rose 2km into the air, according to the nation's geological authority.
The outbursts that unfolded throughout the day compelled authorities to increase the volcano’s alert level on two occasions, from the third-highest level to the top level, the authority reported. No casualties have been reported.
Over three hundred inhabitants in the three communities most at risk in the area of Lumajang region were relocated to government shelters, as mentioned by a spokesperson for the national emergency management body.
He stated that increased activity of the volcano on Wednesday afternoon prompted officials to expand the hazard area to 8km from the summit. People were urged to keep away from an area along the Kobokan River, which is the path of the lava flow, as scorching gases moved down the volcano's sides.
Videos on online platforms showed a dense cloud of ash sweeping through a forested valley to a river beneath a overpass. Residents, some with faces smeared with volcanic dust and water, fled to makeshift refuges or departed for alternative secure locations.
Regional news outlets reported that emergency teams were facing challenges to rescue about 178 people trapped on the 3,676-metre peak at the Ranu Kumbolo monitoring post. The group included 137 climbers, 15 porters, seven guides and six travel representatives, according to an official with the national park.
“They are currently safe at Ranu Kumbolo monitoring post,” an official said in a recorded message. He noted the post was situated 2.8 miles from the crater on the northern slope of the volcano, which is outside the trajectory of the fiery cloud movement that was observed moving to the southeast direction. Bad weather and precipitation required the group to remain overnight there, he explained.
Semeru, also called Mahameru, has erupted numerous times in the past 200 years. Still, as is the situation with numerous of the 129 active volcanoes in the archipelago, thousands of residents continue 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 more were burned and settlements were submerged in layers of mud. The event led to the evacuation of more than 10,000 people from their homes.
Indonesia, an island chain of over 280 million people, sits along the Pacific “ring of fire”, a curved series of fault lines, and is prone to seismic events and volcanism.
