Dramatic footage shows moment Indonesia tsunami hits band performing on beach

Dramatic footage shows the moment a devastating tsunami hit Indonesia on Sunday morning (NZ time), taking the lives of several victims.

Video of the tragedy, which happened as Jakartan pop band Seventeen performed at a beach resort, was captured on camera by a concert-goer.

As the group played, the stage was suddenly swept away by the giant wave while people screamed and ran.

The band's lead vocalist Riefian Fajarsyah posted a tearful video to Instagram saying that their bassist and manager had been lost.

His wife, actress Dylan Sahara, and several other band personnel were also among the missing, he said.

It is believed that underwater landslides triggered by volcanic eruptions could have caused the tsunami, which has claimed the lives of at least 43.

The death toll was expected to grow as missing peoples' reports are still being filed.

Almost 600 people have reported injuries from the disaster so far.

The country's climatology agency BMKG said the eruption of Mount Anak Krakatau took place at 9:03pm and the waves hit land at around 9:27pm on Saturday night.

In 2004, an estimated 230,000 people were killed on Boxing Day when a tsunami struck 13 countries on the Indian Ocean, including Indonesia, Sri Lanka, India and Thailand.
