Mount Mahameru Eruption in Indonesia Triggers Emergency Relocations
The nation's Semeru volcano, the highest peak on the island of Java, has exploded, covering several villages with volcanic ash, leading to evacuations and leading authorities to raise the alert to the maximum level.
The volcano in East Java province released searing clouds of hot ash and a mixture of rock, lava and gas that travelled up to 7km down its slopes several times from midday to evening, while a thick column of fiery clouds rose 2km into the air, according to the nation's geological authority.
The eruptions that unfolded throughout the day forced authorities to increase the mountain's warning status on two occasions, from the level three to the top level, the agency said. No casualties have been announced.
Over three hundred residents in the three villages most endangered in the district of Lumajang region were evacuated to official safe havens, according to a spokesperson for the national emergency management body.
He said that heightened volcanic movements of the mountain on the afternoon of Wednesday led officials to widen the danger zone to 5 miles from the summit. People were urged 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 the volcano's sides.
Videos on online platforms displayed a thick plume of ash moving through a wooded ravine to a river beneath a overpass. Residents, some with faces covered with ash and rain, fled to makeshift refuges or left for alternative secure locations.
Local media reported 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 comprised 137 hikers, 15 porters, seven guides and six travel representatives, according to an spokesperson with the national park.
“They are currently safe at Ranu Kumbolo monitoring post,” a spokesperson said in a recorded message. He said the station was situated 2.8 miles from the crater on the northern slope of the volcano, which is not in the path of the fiery cloud movement that was observed moving to the south-southeast. Inclement conditions and precipitation required the group to remain overnight there, he explained.
The volcano, also called Mahameru, has erupted numerous times in the past 200 years. However, as is the situation with numerous of the 129 live volcanoes in the archipelago, thousands of residents continue to reside on its fertile slopes.
The mountain's previous significant explosion was in December 2021, when 51 individuals were lost their lives and several hundred others were burned and settlements were buried in layers of mud. The event led to the relocation of more than 10,000 people from their homes.
The country, an archipelago of over 280 million inhabitants, is located along the Pacific “ring of fire”, a curved series of tectonic boundaries, and is susceptible to seismic events and volcanic activity.
