At least another 745 were injured by the wave, triggered by an underwater landslide from volcanic eruptions.
People ran in fear as five metre waves flooded streets and swept away homes and vehicles last night, local time.
A dramatic video posted on social media shows the Jakarta pop band Seventeen performing at a tent at a beach when a wave collapses their stage from behind.
People scream and run.
The band’s bass player and road manager are among the dead, while four other members of the group remain missing.
