Mount Semeru Eruption in the Southeast Asian nation Triggers Evacuations
The nation's Semeru volcano, the highest peak on the island of Java, has exploded, covering multiple communities with falling ash, leading to evacuations and leading authorities to raise the warning to the highest level.
The volcano in East Java province released searing clouds of hot ash and a mixture of stone, molten rock, and gases that travelled up to 7km down its slopes multiple times from midday to dusk, while a dense plume of fiery clouds rose 1.2 miles into the air, as stated by the nation's geological authority.
The outbursts that occurred throughout the day forced officials to increase the mountain's warning status on two occasions, from the level three to the top level, the authority said. No casualties have been reported.
Over three hundred residents in the three villages most at risk in the area of Lumajang were relocated to government shelters, as mentioned by a spokesperson for the national emergency management body.
He said that heightened volcanic movements of the mountain on the afternoon of Wednesday prompted authorities to widen the danger zone to 5 miles from the summit. Residents were advised to keep away from an area along the Kobokan River, which is the path of the lava flow, as scorching gases moved down Semeru’s slopes.
Videos on social media displayed a thick plume of volcanic dust moving through a forested valley to a river beneath a bridge. Residents, some with faces covered with volcanic dust and water, escaped to makeshift refuges or departed for alternative secure locations.
Regional news outlets indicated that emergency teams were facing challenges to save about 178 individuals stranded on the 3,676-metre peak at the Ranu Kumbolo monitoring post. The group included 137 hikers, 15 porters, seven escorts and six travel representatives, according to an spokesperson with the protected area.
“They are currently safe at the Ranu Kumbolo station,” a spokesperson said in a recorded message. He said the post was located 2.8 miles from the summit on the north side of the mountain, which is outside the trajectory of the fiery cloud movement that was observed moving to the southeast direction. Bad weather and rain required the team to remain overnight there, he added.
The volcano, also called Great Mountain, has erupted numerous times in the last two centuries. However, as is the situation with numerous of the 129 active volcanoes in the archipelago, thousands of residents continue to live on its fertile slopes.
The mountain's last major eruption was in late 2021, when 51 people were killed and hundreds more were injured and villages were buried in thick mud. The event forced the relocation of more than 10,000 residents from their homes.
The country, an archipelago of more than 280 million people, sits along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is susceptible to earthquakes and volcanism.
