MOUNT MERAPI, Indonesia (AP) -- Soldiers wearing heat-retardant clothing dug through volcanic debris Thursday trying to reach two people trapped in an underground emergency shelter on Indonesia's most volatile volcano, officials said.

The fierce heat melted the troops' shovels and the tires on a mechanical digger brought in to plow through more than six feet of debris covering the bunker, which was built for protection from volcanic eruptions, said Maj. Sunarso, who goes by one name.

The two men have been trapped since late Wednesday when Merapi sent massive clouds of searing gas and rock fragments rolling far down its slopes.

By nightfall, the soldiers had dug away the debris surrounding the door, but found it blocked by a large hot boulder, said senior disaster official Heka, who also goes by a single name.

The operation was suspended until Friday morning.

The eruption Wednesday came just a day after officials lowered the alert level and people had returned to their homes around Mount Merapi. (Watch people flee as volcano erupts on Wednesday -- 1:49)

"The situation is ... life-threatening," said Yousana Siagian, head of the government's Vulcanology and Disaster Mitigation Center.

The alert level for Mount Merapi was raised to its highest status again as the volcano dumped thick ash on scores of houses.

Five villagers were reported missing in addition to the two people trapped in the emergency shelter.

The rescuers had been in touch with the two by cell phone. The bunkers, several of which dot the slopes of Merapi, are typically equipped with water and food.

Scientists had thought the 9,700-foot volcano was calming after weeks of activity when a gas cloud cracked its fragile lava dome June 8, easing the buildup of pressure.

The alert level was dropped a notch Tuesday, sparking widespread relief for people who have spent weeks in evacuation camps and were trucked home.

That quickly turned to concern Wednesday as Merapi demonstrated its famed unpredictability.

"We were very happy to go back in the morning, but as soon as we got there, we saw a massive cloud steaming toward us," villager Edi Egan said after being trucked back to the camp. "We all decided it was time to leave."

Up to 20,000 people live in the danger zone, taking advantage of the rich volcanic soil. By nightfall, at least 1,100 were back in camps and some 12,000 others were given orders to leave.

A superheated gas cloud nearly enveloped the village of Kaliadem, the closest residential area to the peak, only four miles away, said Siagian, the government vulcanologist.

A similar cloud killed 60 people in 1994, and about 1,300 people died when Merapi erupted in 1930.

Siagian said Merapi spewed hot clouds as far as four miles from the volcano's crater -- the farthest since the alert status was first raised to the highest level on May 13.

Ash covered one village 4.5 miles west of the crater with a gray blanket an inch thick, and soot rained down after dusk across many areas, officials said.

As villagers started returning home Tuesday, they were told to stay alert, and evacuation trucks remained on standby. They quickly sprung back into action.

"The villagers are confused. They said it was safe, but hot clouds re-emerged. One thing is for sure -- we have readied ourselves to evacuate anytime," said Budiono, chief of Ngargosoko, a village six miles from the peak that was ordered evacuated.

Some 12,000 residents of seven villages on the mountain's west side have been ordered to leave, said district official Edy Susanto.

"A heavy rain of ash and sand poured down on villagers," said Sugiono, an official from a monitoring post. He said it was very dark in the village, which was covered with smoke and ash. "People instinctively came to the shelters."

Despite the danger, many people have stayed put over the last month, citing the need to guard their homes and look after crops and animals.

The main dangers at Merapi are fast-moving bursts of blistering gases and rock fragments called pyroclastic flow. Experts say a massive vertical eruption threatening people many miles away will not occur.
