Authorities in Japan have ordered almost 250,000 from their homes following Saturday's 7.3 magnitude earthquake.
The search for survivors continues in the Kumamoto province on the island of Kyushu, where two quakes struck over 24 hours killing at least 32 people.
Inclement weather is hampering rescue efforts with heavy rain and wind forecast and temperatures set to plummet.
Firefighters have been handing out tarpaulins to residents so they can cover damaged roofs and protect themselves.
Japans' Prime Minister Shinzo Abe told a government meeting that the weather was expected to get worse.
"Rescue operations at night will be extremely difficult ... It's a race against time," he said.
