Volcano Semeru Eruption in Indonesia Triggers Evacuations
The nation's Mount Semeru, the highest peak on Java island, has exploded, blanketing multiple communities with falling ash, prompting evacuations and causing officials to elevate the alert to the maximum level.
The mountain in East Java province released searing clouds of fiery ash and a combination of stone, molten rock, and gases that travelled up to 7km down its slopes several times from noon to evening, while a thick column of fiery clouds rose 2km into the sky, according to the nation's geological authority.
The eruptions that unfolded throughout the day compelled officials to raise the volcano’s alert level twice, from the third-highest level to the highest, the authority said. No deaths or injuries have been reported.
Over three hundred inhabitants in the three villages most at risk in the district of Lumajang were relocated to government shelters, as mentioned by a representative for the national disaster mitigation agency.
He said that increased activity of the volcano on Wednesday afternoon prompted officials to expand the hazard area to 8km from the crater. People were advised 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.
Videos on social media showed a dense cloud of ash sweeping through a forested valley to a waterway beneath a overpass. Locals, some with faces covered with ash and rain, escaped to temporary shelters or left for alternative secure locations.
Regional news outlets indicated that emergency teams were facing challenges to save about 178 people trapped on the 12,060-foot peak at the Ranu Kumbolo monitoring post. The party comprised 137 climbers, 15 porters, seven guides and six travel representatives, according to an official with the national park.
“They remain secure at Ranu Kumbolo monitoring post,” a spokesperson stated in a video statement. He noted the post was situated 4.5km from the summit on the north side of the volcano, which is outside the trajectory of the hot cloud flow that was seen moving to the southeast direction. Bad weather and precipitation forced the group to remain overnight there, he added.
Semeru, also known as Mahameru, has erupted many occasions in the last two centuries. However, as is the situation with many of the 129 active volcanoes in the archipelago, tens of thousands of residents continue to live on its productive highlands.
Semeru’s previous significant explosion was in late 2021, when 51 people were killed and several hundred more were injured and villages were submerged in layers of mud. The event forced the relocation of over ten thousand people from their homes.
The country, an archipelago of more than 280 million people, is located along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is prone to earthquakes and volcanic activity.
