Search operations resumed Wednesday at the Mount Ontake volcano eruption site in Japan.
Rescue teams comprising police, firefighters and self-defence forces have been deployed at the site, Kyodo News reported.
Search operations were hit by bad weather and volcanic activity Tuesday.
A sudden volcanic eruption at Mount Ontake in central Japan Sep 27 killed 36 people and left 250 injured.
Ontake was thought to be inactive until October 1979, when it underwent a series of explosive eruptions, spewing over 200,000 tonnes of ash.
Japan is one of the world's most seismically active countries.
In 1991, at least 43 people were killed when Mount Unzen erupted in the country's south-west region.
