Mount Semeru Eruption in Indonesia Triggers Emergency Relocations
Indonesia's Semeru volcano, the tallest summit on the island of Java, has exploded, covering several villages with volcanic ash, leading to evacuations and leading authorities to raise the warning to the highest level.
The volcano in the province of East Java released blistering plumes of fiery ash and a combination of stone, molten rock, and gases that moved up to 4 miles down its sides multiple 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 outbursts that unfolded throughout the day compelled officials to increase the volcano’s alert level twice, from the third-highest level to the top level, the authority said. No deaths or injuries have been announced.
Over three hundred residents in the three villages most endangered in the district of Lumajang region were relocated to official safe havens, according to a spokesperson for the national emergency management body.
He stated that increased activity of the volcano on the afternoon of Wednesday led officials to widen the danger zone to 5 miles from the crater. Residents were urged to keep away from an area along the Kobokan River, which is the path of the molten rock stream, as searing gas flowed down Semeru’s slopes.
Footage on online platforms showed a dense cloud of ash sweeping through a wooded ravine to a river beneath a overpass. Locals, some with faces covered with volcanic dust and rain, escaped to temporary shelters or left for alternative secure locations.
Local media indicated that authorities were struggling to rescue about 178 people stranded on the 3,676-metre mountain at the Ranu Kumbolo observation station. The group comprised 137 climbers, 15 carriers, 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 4.5km from the crater on the north side of the mountain, which is not in the path of the fiery cloud movement that was seen traveling to the south-southeast. Bad weather and rain forced the group to spend the night there, he explained.
The volcano, also called Mahameru, has burst many occasions in the past 200 years. However, as is the case with many of the 129 live volcanoes in Indonesia, tens of thousands of people still to live on its fertile slopes.
The mountain's previous significant explosion was in December 2021, when 51 individuals were killed and several hundred more were burned and settlements were submerged in thick mud. The eruption led to the relocation of over ten thousand people from their homes.
Indonesia, an island chain of more than 280 million inhabitants, sits along the Pacific “ring of fire”, a horseshoe-shaped series of tectonic boundaries, and is prone to earthquakes and volcanic activity.
