Volcano Semeru Outburst in Indonesia Triggers Evacuations
The nation's Mount Semeru, the highest peak on Java island, has exploded, covering multiple communities with falling ash, leading to evacuations and leading authorities to raise the alert to the maximum level.
The mountain in the province of East Java unleashed blistering plumes of fiery ash and a combination of rock, lava and gas that moved up to 7km down its sides several times from midday to dusk, while a thick column of fiery clouds rose 1.2 miles into the sky, as stated by the nation's geological authority.
The eruptions that occurred throughout the day compelled officials to increase the mountain's warning status twice, from the level three to the highest, the authority reported. No deaths or injuries have been reported.
Over three hundred residents in the three communities most at risk in the district of Lumajang were evacuated to official safe havens, as mentioned by a spokesperson for the national emergency management body.
He said that increased activity of the mountain on the afternoon of Wednesday led officials to widen the hazard area to 5 miles from the summit. Residents were urged to stay clear from an area along the Besuk Kobokan River, which is the route of the lava flow, as searing gas flowed down Semeru’s slopes.
Videos on social media displayed a dense cloud of ash moving through a forested valley to a waterway beneath a bridge. Residents, some with faces covered with volcanic dust and water, fled to temporary shelters or left for alternative secure locations.
Local media reported that authorities were facing challenges to save about 178 people trapped on the 12,060-foot mountain at the Ranu Kumbolo monitoring post. The group comprised 137 hikers, 15 carriers, seven guides and six tourism officials, according to an official with the national park.
“They are currently safe at the Ranu Kumbolo station,” a spokesperson said in a recorded message. He said the post was situated 2.8 miles from the summit on the northern slope of the volcano, which is outside the trajectory of the fiery cloud movement that was observed traveling to the south-southeast. Bad weather and rain forced the group to remain overnight there, he explained.
The volcano, also known as Mahameru, has erupted many occasions in the past 200 years. However, as is the situation with many of the 129 live volcanoes in Indonesia, thousands of people still to live on its fertile slopes.
Semeru’s last major eruption was in December 2021, when 51 individuals were killed and several hundred others were burned and villages were submerged in layers of mud. The eruption forced the evacuation of more than 10,000 people from their homes.
The country, an island chain of more than 280 million inhabitants, is located along the Pacific “ring of fire”, a curved series of tectonic boundaries, and is susceptible to seismic events and volcanism.
