Volcano Semeru Eruption in Indonesia Prompts Emergency Relocations
Indonesia's Semeru volcano, the tallest summit on Java island, has exploded, covering multiple communities with volcanic ash, prompting evacuations and causing officials to elevate the alert to the maximum level.
The mountain in the province of East Java released searing clouds of hot ash and a mixture of rock, lava and gas that travelled up to 4 miles down its slopes several times from noon to dusk, while a thick column of fiery clouds rose 2km into the air, as stated by Indonesia’s Geology Agency.
The eruptions that unfolded throughout the day forced officials to increase the volcano’s alert level twice, from the third-highest level to the top level, the authority said. No casualties have been announced.
More than 300 residents in the three villages most endangered in the area of Lumajang region were relocated to official safe havens, as mentioned by a representative for the national emergency management body.
He said that increased activity of the volcano on the afternoon of Wednesday prompted officials to widen the danger zone to 8km from the summit. Residents were urged to keep away from an zone along the Kobokan River, which is the path of the lava flow, as scorching gases moved down the volcano's sides.
Videos on social media displayed a thick plume of volcanic dust moving through a wooded ravine to a waterway beneath a overpass. Residents, some with faces covered with volcanic dust and water, fled to temporary shelters or departed for other safe areas.
Local media indicated that emergency teams were facing challenges to rescue about 178 people stranded on the 3,676-metre mountain at the Ranu Kumbolo observation station. The group comprised 137 hikers, 15 carriers, seven escorts and six travel representatives, according to an spokesperson with the national park.
“They remain secure at Ranu Kumbolo monitoring post,” a spokesperson stated 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 southeast direction. Bad weather and rain required the group to spend the night there, he explained.
Semeru, also called Mahameru, has burst numerous times in the past 200 years. Still, as is the situation with numerous of the 129 active volcanoes in the archipelago, thousands of people still to live on its productive highlands.
Semeru’s last major eruption was in late 2021, when 51 people were lost their lives and hundreds others were injured and villages were buried in thick mud. The event forced the relocation of more than 10,000 people from their houses.
Indonesia, an archipelago of over 280 million inhabitants, is located along the Pacific seismic belt, a curved series of fault lines, and is susceptible to earthquakes and volcanic activity.
