Mount Mahameru Eruption in Indonesia Prompts Emergency Relocations
Indonesia's Semeru volcano, the highest peak on Java island, has exploded, blanketing multiple communities with volcanic ash, prompting evacuations and causing officials to elevate the warning to the maximum level.
The volcano in the province of East Java unleashed searing clouds of fiery ash and a mixture of rock, lava and gas that travelled up to 7km down its slopes multiple times from noon to dusk, while a thick column of hot 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 mountain's warning status on two occasions, from the third-highest level to the top level, the agency said. No casualties have been reported.
Over three hundred inhabitants in the three communities most endangered in the area of Lumajang region were relocated to government shelters, according to a spokesperson for the national emergency management body.
He said that heightened volcanic movements of the mountain on Wednesday afternoon prompted officials to widen the hazard area to 5 miles from the summit. Residents were advised to stay clear from an zone along the Kobokan River, which is the route of the molten rock stream, as searing gas flowed down the volcano's sides.
Footage on social media displayed a thick plume of ash moving through a wooded ravine to a waterway beneath a overpass. Residents, some with faces smeared with volcanic dust and water, escaped to temporary shelters or departed for alternative secure locations.
Local media indicated that authorities were struggling to save about 178 people trapped on the 12,060-foot peak at the Ranu Kumbolo observation station. The party included 137 climbers, 15 carriers, seven guides and six travel representatives, according to an spokesperson with the national park.
“They remain secure at the Ranu Kumbolo station,” a spokesperson said in a video statement. He noted the station was located 2.8 miles from the crater on the northern slope of the volcano, which is not in the path of the hot cloud flow that was observed traveling to the southeast direction. Bad weather and precipitation forced the team to spend the night there, he explained.
Semeru, also known as 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, tens of thousands of people still to live on its productive highlands.
The mountain's previous significant explosion was in December 2021, when 51 people were killed and hundreds others were burned and villages were buried in layers of mud. The eruption forced the relocation of more than 10,000 residents from their homes.
Indonesia, an archipelago of over 280 million people, sits along the Pacific “ring of fire”, a horseshoe-shaped series of fault lines, and is susceptible to earthquakes and volcanism.
