Indonesia's Mount Semeru, the tallest summit on the island of Java, has erupted, covering multiple communities with falling ash, leading to evacuations and leading authorities to raise the warning to the highest level.
The volcano in the province of East Java unleashed blistering plumes of hot ash and a mixture of rock, lava and gas that travelled up to 7km down its slopes multiple times from noon to evening, while a dense plume of fiery clouds rose 1.2 miles into the sky, as stated by the nation's geological authority.
The outbursts that occurred throughout the day compelled officials to increase the mountain's warning status twice, from the third-highest level to the highest, the agency said. No casualties have been announced.
Over three hundred residents in the three communities most endangered in the area of Lumajang were relocated to official safe havens, as mentioned by a spokesperson for the national emergency management body.
He stated that heightened volcanic movements of the volcano on the afternoon of Wednesday prompted authorities to expand the danger zone to 8km from the summit. People were advised to stay clear from an zone along the Besuk Kobokan River, which is the route of the molten rock stream, as searing gas moved down Semeruâs slopes.
Videos on social media showed a dense cloud of volcanic dust sweeping through a wooded ravine to a river beneath a bridge. Locals, some with faces smeared with ash and rain, escaped to temporary shelters or left for other safe areas.
Local media indicated that authorities were facing challenges to rescue about 178 people trapped on the 3,676-metre mountain at the Ranu Kumbolo monitoring post. The party included 137 climbers, 15 porters, seven escorts and six travel representatives, according to an spokesperson with the protected area.
âThey remain secure at Ranu Kumbolo monitoring post,â a spokesperson stated in a recorded message. He said the post was situated 2.8 miles from the crater on the north side of the volcano, which is outside the trajectory of the fiery cloud movement that was seen moving to the south-southeast. Inclement conditions and rain forced the team to spend the night there, he added.
The volcano, also known as Great Mountain, has burst numerous times in the last two centuries. However, as is the case with many of the 129 live volcanoes in the archipelago, tens of thousands of people continue to reside on its fertile slopes.
Semeruâs last major eruption was in December 2021, when 51 people were killed and several hundred others were burned and settlements were buried 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 âring of fireâ, a curved series of tectonic boundaries, and is susceptible to earthquakes and volcanic activity.
