Casualties mount in Hiroshima landslide

TOKYO — At least six people were confirmed dead and 22 were missing after rain-sodden hills in the outskirts of Hiroshima gave way early Wednesday in several landslides.

Video footage from the national broadcaster NHK showed suburban homes in the western Japanese city surrounded by streams of mud and debris, and residents picking their way over piles of rocks and dirt.

Rescue workers suspended by ropes from police helicopters were pulling victims from the rubble as they searched homes stranded amid piles of lumber from crushed houses.

The Fire and Disaster Management Agency, citing the local government, said six people were confirmed dead and another 22 were missing as of late morning. It said at least 20 people were injured, one seriously.

NHK, citing local police, put the death toll at 18.

“A few people were washed away and it is hard to know exactly how many are unaccounted for,” said local government official Nakatoshi Okamoto, noting that the conditions in the disaster area were hindering efforts to account for all those affected.

Authorities issued warnings that further rains could trigger more landslides and flooding.

Landslides are a constant risk in mountainous, crowded Japan, where many homes are built on or near steep slopes. Torrential rains in the early morning apparently caused slopes to collapse in an area where many of the buildings were newly constructed.

Damage from land and mudslides has increased over the past few decades due to more frequent heavy rains, despite extensive work on stabilizing slopes. In the past decade there have been nearly 1,200 landslides a year, according to the land ministry, up from an average of about 770 a year in the previous decade.

In October last year, multiple mudslides on Izu-Oshima, an island south of Tokyo, killed 35 people, four of whose bodies were never recovered. Those slides followed a typhoon that dumped a record 824 millimeters (more than 32 inches) of rain in a single day.
