Volcano Semeru Eruption in the Southeast Asian nation Prompts Emergency Relocations

The nation's Mount Semeru, the highest peak on Java island, has erupted, covering several villages with volcanic ash, leading to evacuations and causing officials to elevate the warning to the maximum level.

The volcano in East Java province unleashed blistering plumes of fiery ash and a combination of stone, molten rock, and gases that travelled up to 7km down its slopes several times from midday to evening, while a thick column of fiery clouds rose 1.2 miles into the sky, as stated by the nation's geological authority.

The eruptions that unfolded throughout the day compelled officials to raise the volcano’s alert level twice, from the third-highest level to the highest, the agency reported. No casualties have been reported.

More than 300 residents in the three villages most endangered in the district of Lumajang region were relocated to official safe havens, as mentioned by a spokesperson for the national emergency management body.

He said that increased activity of the volcano on the afternoon of Wednesday prompted officials to expand the hazard area to 5 miles from the summit. Residents were urged to stay clear from an zone along the Kobokan River, which is the path of the lava flow, as scorching gases moved down the volcano's sides.

Footage on online platforms displayed a dense cloud of ash sweeping through a forested valley to a river beneath a overpass. Locals, some with faces covered with ash and water, fled to makeshift refuges or left for alternative secure locations.

Regional news outlets reported that authorities were struggling to save about 178 people trapped on the 3,676-metre mountain at the Ranu Kumbolo observation station. The group comprised 137 climbers, 15 porters, seven escorts and six tourism officials, according to an official with the protected area.

“They are currently safe at the Ranu Kumbolo station,” an official said in a video statement. He said the post was located 2.8 miles from the crater on the north side of the mountain, which is outside the trajectory of the fiery cloud movement that was observed traveling to the southeast direction. Bad weather and precipitation forced the team to remain overnight there, he explained.

The volcano, also known as Great Mountain, has erupted many occasions in the past 200 years. Still, as is the situation with many of the 129 live volcanoes in the archipelago, tens of thousands of people still to reside on its fertile slopes.

The mountain's last major eruption was in late 2021, when 51 people were lost their lives and several hundred more were burned and settlements were submerged in layers of mud. The eruption led to the evacuation of over ten thousand people from their homes.

The country, an island chain of more than 280 million inhabitants, is located along the Pacific seismic belt, a curved series of tectonic boundaries, and is susceptible to earthquakes and volcanic activity.
