Zhafirah Zahrim Febrina was one of the climbers who was trapped on Mount Marapi when it erupted.
The 19-year-old student, whose nickname is Ife, recorded a video in which she was covered in ash, asking her mother for help.
“Mom, help Ife. This is Ife’s situation right now,” she said.
She was on a hiking trip with 18 school friends and is now in hospital receiving treatment.
