I led hikers up an Indonesian volcano - and then it erupted

Local villagers whom he regularly employs to assist him in escorting groups up Dukono also did not tell him anything about the prohibition, he added.'Rocks falling to our left and right'Reza runs a tour company in North Maluku. He said he was contacted last year by Timothy Heng, a Singaporean who organised adventure expeditions, to guide a group of hikers up Dukono and other mountains in the region.When the group began hiking up Dukono last Thursday afternoon, "there were no signs of volcanic activity. There was no eruption or anything. Nothing."It was also calm the next morning as they summited the mountain, Reza recalled. When he sent up a drone camera to check the crater, "there was no visible activity, there was no smoke either".He told the group they could go up to the crater as long as they made sure to descend shortly afterwards. A total of 14 hikers including Heng went up, while Reza and the rest stayed below.At 07:40 local time, Reza said, he flew his drone up to monitor the group. One minute later, the mountain erupted."Within one minute there were two eruptions. The first eruption only released smoke. Maybe around 15 or 20 seconds later, the second eruption happened and it released all the [volcanic] material," he said.
