Volcano Semeru Outburst in the Southeast Asian nation Prompts Emergency Relocations
Indonesia's Semeru volcano, the highest peak on Java island, has exploded, blanketing several villages with volcanic ash, leading to evacuations and leading authorities to raise the alert to the maximum level.
The mountain in East Java province released blistering plumes of fiery ash and a combination of stone, molten rock, and gases that travelled up to 7km down its sides several times from noon to dusk, while a dense plume of fiery clouds rose 1.2 miles into the air, according to the nation's geological authority.
The eruptions that unfolded throughout the day forced officials to increase the mountain's warning status twice, from the third-highest level to the top level, the authority reported. No deaths or injuries have been reported.
More than 300 inhabitants in the three villages most endangered in the area of Lumajang region were evacuated to government shelters, according to a spokesperson for the national emergency management body.
He said that increased activity of the mountain on Wednesday afternoon led officials to expand the danger zone to 8km from the crater. People were urged to stay clear from an area along the Kobokan River, which is the route of the lava flow, as searing gas flowed down the volcano's sides.
Videos on online platforms displayed a thick plume of ash moving through a forested valley to a river beneath a overpass. Residents, some with faces smeared with volcanic dust and water, escaped to temporary shelters or left for other safe areas.
Local media indicated that authorities were struggling to rescue about 178 people trapped on the 12,060-foot mountain at the Ranu Kumbolo monitoring post. The group included 137 climbers, 15 porters, seven escorts and six tourism officials, according to an official with the protected area.
“They are currently safe at Ranu Kumbolo monitoring post,” an official stated in a recorded message. He said the post was located 2.8 miles from the summit on the north side of the volcano, which is not in the path of the hot cloud flow that was seen traveling to the south-southeast. Inclement conditions and rain required the group to spend the night there, he added.
The volcano, also known as Great Mountain, has erupted many occasions in the last two centuries. However, as is the situation with numerous of the 129 active volcanoes in Indonesia, thousands of people continue to live on its fertile slopes.
The mountain's previous significant explosion was in December 2021, when 51 individuals were lost their lives and hundreds more were burned and villages were buried in layers of mud. The event led to the relocation of more than 10,000 residents from their houses.
The country, an archipelago of over 280 million people, is located along the Pacific “ring of fire”, a curved series of tectonic boundaries, and is prone to earthquakes and volcanism.
