Eleven climbers have been confirmed dead in Indonesia after the Marapi volcano erupted in West Sumatra. The search for 12 more missing was temporarily stopped due to safety concerns.
Three survivors were discovered on Monday, along with the deaths of 11 climbers who were among 75 people in the region at the time of the eruption on Sunday, according to Jodi Haryawan, a spokesperson for the search and rescue team.
On Sunday, the volcano's height of 2,891 meters blasted ash up to 3 kilometers into the sky.

Authorities upped the alert to the second-highest level and prevented residents from approaching the crater within 3 kilometers.
A viral video showed a massive cloud of volcanic ash stretched across the sky, and cars and roadways were covered in ash.
The search was halted on Monday due to a minor explosion, according to Jodi.
"It's too dangerous if we continue searching now," he added.
He said 49 climbers were removed from the region early Monday, and many were treated for burns.
Marapi is one of Sumatra's most active volcanoes, and its most fatal eruption occurred in April 1979, killing 60 people.
It erupted in January and February this year, spewing ash 75-1,000 meters from the summit.
According to the volcanology department, Indonesia is located on the Pacific's so-called "Ring of Fire" and has 127 active volcanoes.
