On Indonesia's Sumatra island, icy lava flows and flash floods claimed at least 37 lives


Because the source of Marapi's eruptions is shallow and close to the summit, it is noted for its unexpected, erratic eruptions that aren't brought on by a deep magma migration.


A combination of volcanic debris and stones that cascades down a volcano's slopes during precipitation is called cold lava, or lahar.


On Indonesia's Sumatra island, torrential downpours of chilly lava and mud, coupled with heavy rainfall, caused flash floods that resulted in at least 37 fatalities and over a dozen unaccounted-for deaths, according to authorities on Sunday.


Just before midnight on Saturday, a river in four districts of West Sumatra province broke its banks and tore through mountainside settlements due to monsoon rains and a significant mudslide triggered by a cold lava flow on Mount Marapi. According to Abdul Muhari, a spokesman for the National Disaster Management Agency, the floodwaters carried away individuals and flooded over 100 homes and structures.

The National Search and Rescue Agency said in a statement that by Sunday afternoon, rescuers had found nine more victims in the nearby district of Tanah Datar and extracted 19 remains from the hardest-hit hamlet of Canduang in the Agam district.

According to the agency, one corpse was discovered in the city of Padang Panjang, while eight victims were recovered from mud during the fatal flash floods that also struck Padang Pariaman.


It said that 18 persons are purportedly missing and that searchers are looking for them. According to Padang Panjang Police Chief Kartyana Putra on Sunday, major routes around the Anai Valley Waterfall region in Tanah Datar district were also obstructed by mud during flash floods on Saturday night, preventing access to neighboring towns.

The National Search and Rescue Agency published videos that showed roadways turned into brown, filthy rivers. Just two months had passed since intense rains in West Sumatra's Pesisir Selatan and Padang Pariaman districts caused flash floods and a landslide that claimed the lives of at least 21 people and left five more missing.

23 climbers were killed by the late-year eruption of 2,885-meter (9,465-foot) Mount Marapi, which was caused by an unexpected weekend eruption. According to Indonesia's Centre for Volcanology and Geological Disaster Mitigation, the volcano has been at the third highest of four warning levels since 2011, signaling above-normal volcanic activity under which climbers and villagers must keep more than 3 km (about 2 miles) from the top.


Because the source is shallow and close to the summit, Marapi is renowned for its unexpected eruptions that are hard to anticipate. Its eruptions are also not brought on by a deep flow of magma, which triggers tremors that may be detected by seismic sensors.

Its eruptions are also not brought on by a deep flow of magma, which triggers tremors that may be detected by seismic sensors. Since an eruption that didn't result in any deaths in January 2023, Marapi has been active.


It is one among Indonesia's more than 120 active volcanoes. Because of its position on the Pacific Ring of Fire, an arc of volcanoes and fault lines around the Pacific Basin, the nation is vulnerable to seismic upheaval.
