Mount Mahameru Outburst in Indonesia Triggers Evacuations
The nation's Mount Semeru, the highest peak on the island of Java, has erupted, covering multiple communities with volcanic ash, leading to evacuations and leading authorities to raise the alert to the maximum level.
The volcano in the province of East Java released searing clouds of hot ash and a combination of stone, molten rock, and gases that moved up to 4 miles down its sides several times from noon to evening, while a thick column of hot clouds rose 1.2 miles into the air, as stated by the nation's geological authority.
The eruptions that occurred throughout the day compelled officials to increase the volcano’s alert level on two occasions, from the level three to the highest, the authority reported. No casualties have been reported.
More than 300 residents in the three villages most at risk in the area of Lumajang region were relocated to government shelters, according to a representative for the national disaster mitigation agency.
He said that increased activity of the volcano on Wednesday afternoon led officials to widen the danger zone to 5 miles from the summit. Residents were urged to stay clear from an area along the Kobokan River, which is the route of the molten rock stream, as scorching gases moved down the volcano's sides.
Videos on online platforms showed a dense cloud of ash moving through a forested valley to a waterway beneath a overpass. Residents, some with faces covered with volcanic dust and water, escaped to temporary shelters or left for other safe areas.
Local media reported that authorities were facing challenges to save about 178 individuals stranded on the 12,060-foot mountain at the Ranu Kumbolo monitoring post. The group comprised 137 climbers, 15 carriers, seven guides and six tourism officials, according to an spokesperson with the protected area.
“They remain secure at the Ranu Kumbolo station,” a spokesperson stated in a recorded message. He noted the post was located 4.5km from the crater on the north side of the volcano, which is not in the path of the hot cloud flow that was observed traveling to the south-southeast. Bad weather and rain required the team to remain overnight there, he explained.
Semeru, also known as Great Mountain, has erupted numerous times in the past 200 years. However, as is the situation with many of the 129 active volcanoes in the archipelago, thousands of residents continue to live on its fertile slopes.
Semeru’s last major eruption was in late 2021, when 51 individuals were killed and several hundred others were injured and settlements were submerged in layers of mud. The eruption forced the relocation of more than 10,000 residents from their houses.
Indonesia, an archipelago of more than 280 million people, sits along the Pacific seismic belt, a curved series of fault lines, and is susceptible to earthquakes and volcanic activity.
