December 4, Jakarta (Reuters) - After the Marapi volcano erupted in West Sumatra on Monday, search and rescue efforts resumed after being temporarily suspended due to safety concerns. Eleven climbers were found dead and twelve were reported missing.

Out of the 75 people in the area on Sunday when the eruption occurred, three climbers—all locals—were among the three survivors and their bodies were discovered on Monday, according to Jodi Haryawan, a spokesman for the search and rescue team.

"Up until this evening, we have kept looking for the 12 climbers who went missing. In a phone conversation, Jodi stated, "We have not decided when we are going to stop the operation." She also said they would keep evacuating the three survivors and the climbers' bodies.

According to Jodi, many of the 49 climbers who were evacuated from the area earlier on Monday were receiving burn treatment.

One dead body had to be removed from the volcano in four to six hours, according to Jodi, who also noted that "it's very difficult."

On Sunday, the 2,891-meter (9,485-foot)-tall volcano erupted, shooting ash up to 3 kilometers into the sky.

One of Sumatra's most active volcanoes, Marapi, killed sixty people during its most catastrophic eruption in April 1979. This year, it erupted in January and February, ejecting ash from the peak at a height of between 75 and 1,000 meters.

Residents were forbidden from approaching the crater within three kilometers after authorities upgraded the alert to the second-highest level.

A massive cloud of volcanic ash could be seen stretching across the sky in video footage, and ash was also seen covering roads and cars.

The search was put on hold for a few hours on Monday morning due to a minor eruption. Volcanic ash erupted to a height of about 800 meters.

As per the Volcanology Agency, Indonesia is home to 127 active volcanoes and is situated on the Pacific's "Ring of Fire".
