Flooding and repeated mudslides in Asia have killed more than 100 people.
At least 75 of those deaths took place Monday in eastern Indonesia, and 26 fatalities were also reported in Vietnam.
In Indonesia, several days of torrential downpours caused mudslides, which destroyed thousands of homes in the region.
"Earlier Monday morning there were sudden floods but on a small scale. But 30 minutes later I heard a kind of big thunder and I saw powerful waters coming from the mountain. There was chaos and people panicked and tried to run to safety," Wilem Imburi, a 50-year-old Indonesia resident told reporters.
Many of the roads remain underwater, making it difficult for rescue workers to offer aid and search for survivors.
"There are just too many injuries," said Dortheis Sawaki, heading local relief operations, adding that some medical facilities had been hit by power outages and downed phone lines. "We can't handle it alone."
An Indonesian navy warship arrived on Wednesday and is supplying victims with tents, food and medical supplies.
Floods and landslides caused by Asia's rainy season kill hundreds of people every year.
