Flash Floods Hit Nepal’s Manaslu Region After River Blockage
A landslide blocked a river in Nepal’s Manaslu region.
Water built up behind the blockage and then surged downstream with mud, rocks and other debris.
The river began blocking and bursting repeatedly early on October 11.
Communities along the river, including areas toward Jagat and Arughat, faced a threat of more damage.
No deaths or injuries had been reported at the time.
The area was hit by serious floods just weeks earlier, which swept away two bridges.
Residents said they were still recovering from that earlier disaster.
A study also found that a 2024 flood in the area was triggered by an ice avalanche into a glacial lake.
Flash floods carrying mud, debris and large boulders struck Nepal’s Manaslu region on October 11.
A dry landslide blocked the Budhi Gandaki River near Lokpa in Chumnubri, Gorkha district.
The river repeatedly blocked and burst from about 4 a.m., threatening settlements toward Jagat and Arughat.
No casualties had been reported at the time of the report.
The flooding follows September 6 floods that washed away two bridges and disrupted movement on the Manaslu trekking corridor.
