Marapi, which means “Mountain of Fire”, was still billowing a column of smoke into the sky on Wednesday morning before another eruption just after midday local time (0500 GMT), an AFP journalist said.
Officials monitoring the volcano had also detected at least five further eruptions on Tuesday as the search went on.
“SOME JUMPED”
Fifty-two people had been rescued since the eruption and some of the survivors have described their panic after it started.
“I was zig-zagging, going down around 30m to 40m” to a trekking post, Ridho, 22, told AFP from a bed in a nearby hospital.
“The eruption sounded loud, I took a look behind and then immediately ran away as everyone did. Some jumped and fell. I took cover behind the rocks, there were no trees there.”
Suharyono said on Tuesday evening that two of the 75 hikers were police officers, one of whom survived. He suspected the other had been killed.
“They both just wanted to see the volcano, they were off duty,” he said.
“One of them survived and had a broken arm, he is being treated by doctors. For the other one, we suspected he died. Let’s wait for confirmation.”
The head of Indonesia’s volcanology agency, Hendra Gunawan, said Marapi has been at the second level of a four-tier alert system since 2011, and a three-kilometre exclusion zone had been imposed around its crater.
He appeared to blame hikers after the eruption for going too close to the crater, saying the agency recommended no activity in that area.
The official number of hikers given by officials was sourced to an online registration system but officials warned there could have been more on illegal routes.
“Maybe there were hikers who were not registered, and sometimes illegal hikers did not want to pay, they just climbed,” said Suharyono.
Indonesia experiences frequent seismic and volcanic activity due to its position on the Pacific “Ring of Fire”, where tectonic plates collide.
Marapi is the most active volcano on Sumatra and one of nearly 130 active volcanoes in the Indonesian archipelago.
