The death toll from Saturday's eruption of a volcano on the main island of Java rose to 34 on Tuesday after rescuers reached some areas earlier inaccessible, while 22 people remain missing, a military officer said.

Col. Irwan Subekti, commander of the emergency response coordinating post for the disaster, told a press conference that about 4,250 people have been displaced, at least 5,205 houses were damaged and over 100 people were injured from the eruption of Mt. Semeru in East Java Province.

Almost 1,000 rescuers, including from the military and police, have been deployed during the search and rescue operations.

On Tuesday, rescuers searched for residents who could be buried under the volcanic debris in two villages and a sand mining area, which were among the most-affected areas but earlier inaccessible.

Hot ash from the 3,676-meter-high volcano had reached an area as far as 11 kilometers from the crater near its peak, destroying and burning everything -- vegetation, livestock, houses and humans -- along the way.

Subekti said Wednesday's search will rely on "our noses and eyes, as well as information from villagers who know the last whereabouts of their friends, neighbors and relatives."

"Heavy machines have not been able to be used in some affected areas because the soil is still very hot," he said. As of Tuesday, the search for victims has been mostly done manually.

President Joko Widodo visited an affected village to console the victims and hear their stories of what happened, as well as their current conditions.

A villager said that before the eruption, they received a warning from the volcano's monitoring post through their cellular phones, but they did not anticipate the scale.

Others told him they were still looking for their loved ones.

The president said more than 2,000 houses will be relocated to safer areas.
