MOUNT MERAPI, Indonesia – Searing gas avalanched down an Indonesian volcano with a thunderous roar, torching houses and trees and incinerating villagers as they fled Mount Merapi's worst eruption in a century. Scores of bodies found Friday raised the death toll to 122.

The injured — with clothes, blankets and even mattresses fused to their skin by the 1,400 degree Fahrenheit (750 degree Celsius) heat — were carried away on stretchers following the first big explosion just before midnight.

All Friday, Merapi shot towering plumes of ash that dusted the windshields of cars 300 miles (480 kilometers) away. Bursts of hot clouds occasionally interrupted aid efforts, with rescuers screaming "Watch out! Hot cloud!"

The intensifying eruptions have baffled scientists who have monitored the mountain for years and left them uncertain what to expect. Dozens of explosions that followed Merapi's initial blast Oct. 26 had been predicted to ease pressure behind a magma dome.

The danger zone where residents have been ordered to flee has now been expanded to 12 miles (20 kilometers) from the crater.

Friday's explosion — said by volcanologists to be the biggest since the 1870s — hit hardest in Bronggang, a village nine miles (15 kilometers) from the crater. Soldiers joined the rescue operations, pulling at least 78 bodies from homes and streets blanketed by ash up to one foot (30 centimeters) deep.

Crumpled roofs, charred carcasses of cattle and broken chairs — all layered in white soot — dotted the smoldering landscape.

The volcano, in the heart of densely populated Java island, has erupted scores of times in the past, killing more than 1,500 people in the last century alone. But tens of thousands of people live on its rolling slopes, drawn to soil made fertile by lava and volcanic debris.

"The heat surrounded us and there was white smoke everywhere," said Niti Raharjo, 47, who was thrown from his motorbike along with his 19-year-old son while trying to flee.

"I saw people running, screaming in the dark, women so scared they fell unconscious," he said from a hospital where they were both being treated for burns.

"There was an explosion that sounded like it was from a war ... and it got worse, the ash and debris raining down."

The greatest danger posed by Merapi has always been pyroclastic flows — like those that roared down the southern slopes at speeds of up to 60 miles per hour (100 kilometers per hour).

With bodies found in front of houses and in streets, it appeared that many of the villagers died from the searing gas while trying to escape, said Col. Tjiptono, a deputy police chief.

More than 150 injured people — with burns, respiratory problems, broken bones and cuts — waited to be treated at the tiny Sardjito hospital, where the bodies piled up in the morgue, and two other hospitals.

"We're totally overwhelmed here!" said Heru Nogroho, a spokesman at Sardjito.

In terms of the amount of volcanic material released — 1,765 million cubic feet (50 million cubic meter), "it was the biggest in at least a century," Gede Swantika, a state volcanologist, said as plumes of smoke continued to shoot up more than 30,000 feet (10,000 meters).

More than 100,000 people living along Merapi's fertile slopes have been evacuated to crowded emergency shelters, many by force, in the last week. Some return to their villages during lulls in activity, however, to tend to their livestock.

They were told to stay away Friday. The government also announced an $11 million program to buy the cows on the mountain to keep farmers off its slopes, and to provide compensation for animals lost in the eruptions.

Even scientists from Merapi's monitoring station were told they had to pack up and move down the mountain. They were scrambling to repair four of their five seismographs destroyed by the heavy soot showers.

Before Friday, the death toll from Merapi stood at 44, with most dying in its first blast on Oct. 26. With the new deaths around Bronggang it climbed to 122, the National Disaster Management Agency said.

In 1994, 60 people were killed by Merapi, while in 1930, more than a dozen villages were torched, leaving up to 1,300 dead.

Indonesia, a vast archipelago of 235 million people, is prone to earthquakes and volcanos because it sits along the Pacific "Ring of Fire," a horseshoe-shaped string of faults that lines the Pacific Ocean.

The volcano's initial blast occurred less than 24 hours after a towering tsunami slammed into the remote Mentawai islands on the western end of the country, sweeping entire villages to sea, killing at least 428 people and severely taxing Indonesia's relief services.

There, too, thousands of people were displaced, many living in government camps.

Holy wow

Interesting Photos OP.

Yep this bad boy just won't rest.

How do people keep dying around the mountain? I thought they evacuated everyone?

Im guessing that some people refused to leave, same as those that died at St Helens, people refused to believe that the mountain posed them any danger and wouldnt leave.

Merapi Volcano is very volatile, he's like the "super volcano"
in the making, i think the is the possible VEI8 volcano, just watch it closely. scientists say they never see this kind of developments on Merapi, they are shitting their pants!!!

That and I don't think they had the evac zone out far enough for this latest blast.

Unlikely.
While Merapi has a huge magma chamber the fact that is fairly active coupled with the fact that in any magma chamber olny a very small portion of whats there is melt and eruptable.

I said on a thread yesterday that its looking kind of similar to Pinatubo, but that doesnt mean its going to go the same way.

Ill put the limit on VEI 5 but like any volcano you can never be 100% sure it wont do something really out of the ordinary.

i agree, VEI 5, BUT the potential is there imho, for an immense eruption too.

agreed

got to disagree with something you said there

'olny a very small portion of whats there is melt and eruptable.'

how can you KNOW that?

Magma chambers are not all liquid magma. Seismic tomography shows us that. Its a mixture of crystaline mush, melt, solid rock of which most is solid rock, only a very small portion of it would be melt that is eruptable.
