Mount Mahameru Eruption in the Southeast Asian nation Prompts Emergency Relocations
Indonesia's Mount Semeru, the tallest summit on the island of Java, has erupted, covering several villages with volcanic ash, leading to evacuations and causing officials to elevate the alert to the maximum level.
The volcano in East Java province unleashed searing clouds of hot ash and a combination of rock, lava and gas that travelled up to 4 miles down its slopes several times from midday to evening, while a thick column of fiery clouds rose 1.2 miles into the air, as stated by Indonesia’s Geology Agency.
The outbursts that unfolded throughout the day compelled officials to increase the mountain's warning status on two occasions, from the level three to the top level, the authority reported. No casualties have been reported.
More than 300 inhabitants in the three communities most endangered in the district of Lumajang region were relocated to official safe havens, as mentioned by a representative for the national disaster mitigation agency.
He said that increased activity of the mountain on the afternoon of Wednesday prompted authorities to widen the danger zone to 5 miles from the crater. People were advised to keep away from an zone along the Kobokan River, which is the route of the lava flow, as searing gas flowed down Semeru’s slopes.
Footage on social media showed a thick plume of volcanic dust sweeping through a forested valley to a river beneath a overpass. Locals, some with faces smeared with ash and water, fled to temporary shelters or left for alternative secure locations.
Local media indicated that authorities were facing challenges to save about 178 individuals trapped on the 12,060-foot mountain at the Ranu Kumbolo observation station. The party included 137 hikers, 15 porters, seven guides and six travel representatives, according to an spokesperson with the protected area.
“They are currently safe at Ranu Kumbolo monitoring post,” a spokesperson said in a recorded message. He noted the post was situated 2.8 miles from the crater on the north side of the volcano, which is not in the path of the hot cloud flow that was observed moving to the southeast direction. Bad weather and rain required the team to remain overnight there, he explained.
Semeru, also called Mahameru, has burst many occasions in the last two centuries. However, as is the case with many of the 129 live 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 lost their lives and several hundred more were burned and settlements were buried in layers of mud. The event forced the relocation of over ten thousand residents from their homes.
The country, an island chain of over 280 million people, is located along the Pacific “ring of fire”, a curved series of fault lines, and is prone to earthquakes and volcanic activity.
