The rock band Seventeen was swept away by a tsunami while giving a concert on Tanjung Lesung beach in Jakarta, Indonesia on Dec. 22.
Hundreds of employees of state electricity utility and family members gathered for an end-of-year party when the gigantic waves struck the stage, notes Reuters.
“Underwater I could only pray ‘Jesus Christ help!’,” Zack, a crew member, wrote in an Instagram post. “In the final seconds I almost ran out of breath.”
The tsunami was triggered by an underwater landslide after the eruption of the Anak Krakatau volcano.
