TOKYO, Oct. 1  -- Ten more bodies were found as rescue operations, which were halted due to bad weather and intensified volcanic activities, resumed Wednesday on Mt. Ontake in central Japan after a deadly eruption at weekend, according to local report.

The victims were also listed as suffering heart and lung failure until medical examination, and the total death toll are expected to be the highest for a volcano incident in Japan since the end of WWII, said Japan's Kyodo News.

Local authorities have declared 18 people dead and over 25 other are presumed dead, according to Kyodo.

A huge pyroclastic flow at Fugen Peak of Mt. Unzen in southwestern Japan left 43 dead and missing in 1991, the record high in postwar Japan.
