Volcano Mahameru Outburst in the Southeast Asian nation Prompts Evacuations
Indonesia's Mount Semeru, the highest peak on Java island, has exploded, covering multiple communities with volcanic ash, prompting evacuations and causing officials to elevate the alert to the highest level.
The volcano in East Java province unleashed blistering plumes of hot ash and a combination of stone, molten rock, and gases that travelled up to 4 miles down its slopes several times from midday to dusk, while a thick column of hot clouds rose 2km into the air, as stated by Indonesia’s Geology Agency.
The eruptions that unfolded throughout the day forced officials to increase the mountain's warning status on two occasions, from the level three to the highest, the agency reported. No casualties have been announced.
More than 300 residents in the three villages most at risk in the area of Lumajang were evacuated to government shelters, as mentioned by a representative for the national emergency management body.
He stated that heightened volcanic movements of the mountain on Wednesday afternoon led authorities to widen the hazard area to 8km from the crater. People were advised to keep away from an area along the Besuk Kobokan River, which is the path of the molten rock stream, as scorching gases moved down Semeru’s slopes.
Footage on online platforms showed a thick plume of volcanic dust moving through a wooded ravine to a waterway beneath a overpass. Locals, some with faces covered with volcanic dust and water, fled to temporary shelters or left for other safe areas.
Regional news outlets indicated that emergency teams were struggling to save about 178 individuals trapped on the 3,676-metre mountain at the Ranu Kumbolo monitoring post. The party included 137 hikers, 15 porters, seven escorts and six tourism officials, according to an spokesperson with the national park.
“They remain secure 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 northern slope of the mountain, which is not in the path of the hot cloud flow that was observed traveling to the south-southeast. Inclement conditions and rain required the group to spend the night there, he added.
Semeru, also called Great Mountain, has erupted numerous times in the last two centuries. Still, as is the case with numerous of the 129 live volcanoes in the archipelago, tens of thousands of people continue to reside on its productive highlands.
The mountain's last major eruption was in late 2021, when 51 individuals were killed and several hundred others were burned and settlements were buried in layers of mud. The eruption led to the evacuation of over ten thousand people from their houses.
The country, an archipelago of more than 280 million people, is located along the Pacific “ring of fire”, a curved series of fault lines, and is susceptible to seismic events and volcanic activity.
