Volcano Mahameru Eruption in the Southeast Asian nation Prompts Emergency Relocations
Indonesia's Mount Semeru, the tallest summit on the island of Java, has exploded, blanketing multiple communities with volcanic ash, leading to evacuations and causing officials to elevate the alert to the highest level.
The mountain in East Java province unleashed searing clouds of fiery ash and a combination 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 Indonesia’s Geology Agency.
The eruptions that unfolded throughout the day forced authorities to increase the volcano’s alert level on two occasions, from the third-highest level to the highest, the agency reported. No casualties have been announced.
More than 300 residents in the three villages most at risk in the area of Lumajang were evacuated to government shelters, according to a spokesperson for the national disaster mitigation agency.
He said that increased activity of the mountain on the afternoon of Wednesday prompted officials to widen the hazard area to 5 miles from the summit. Residents were urged to keep away from an area along the Kobokan River, which is the route of the molten rock stream, as scorching gases flowed down Semeru’s slopes.
Videos on online platforms displayed a dense cloud of ash moving through a wooded ravine to a waterway beneath a bridge. Residents, some with faces covered with volcanic dust and rain, fled to temporary shelters or left for alternative secure locations.
Local media reported that emergency teams were struggling to rescue about 178 individuals trapped on the 12,060-foot mountain at the Ranu Kumbolo observation station. The group included 137 hikers, 15 porters, seven escorts and six tourism officials, according to an spokesperson with the national park.
“They are currently safe at the Ranu Kumbolo station,” a spokesperson stated in a recorded message. He said the post was located 2.8 miles from the crater on the north side of the volcano, which is outside the trajectory of the hot cloud flow that was seen traveling to the southeast direction. Bad weather and precipitation required the team to spend the night there, he added.
The volcano, also called Mahameru, has burst many occasions 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 reside on its productive highlands.
The mountain's previous significant explosion was in December 2021, when 51 individuals were lost their lives and hundreds others were burned and villages were buried in thick mud. The eruption forced the relocation of more than 10,000 residents from their homes.
Indonesia, an archipelago of more than 280 million inhabitants, is located along the Pacific seismic belt, a curved series of fault lines, and is prone to earthquakes and volcanism.
