Emergency teams had to suspend their work several times on Saturday because of torrential rains. They say there is little hope of finding anyone alive.
Officials say 146 people have died, including at least 27 children and teenagers, while 191 are still missing.
More than 900 people are being housed in schools and shelters.
On Saturday, workers dug with spades and shovels through the rubble and muck in a dense fog. Teams of volunteers are helping in the efforts.
