A dramatic video has been posted online showing the tsunami that struck Indonesia smashing into an open-air concert, hurling members of a pop band from the stage and slamming into the audience.

Two members of the band Seventeen and two crew staff were killed by the waves, which were as a result of an underwater landslide caused by the eruption of the Anak Krakatau volcano.

On the video, fans can be seen clapping and cheering before a wave rips under the stage, sending the band members and their equipment crashing into the men and women dancing at the front.

Seventeen were playing Saturday night, December 22nd, to a large crowd in a marquee at the Tanjung Lesung Beach Resort on the western tip of Java when the wall of water hit.

In an emotional post to his Instagram account, the band’s lead singer Riefian ‘Ifan’ Fajarsyah broke down as he told his 300,000 followers that his friends were missing.

It was later revealed that Awal ‘Bani’ Purbani, road manager Oki Wijaya, guitarist Herman Sikumbang, and crew member Ujang, were found dead.

The singer said:

“(We) lost Bani and our road manager Oki.

“Andi (drummer) and Herman (guitar) and Ujang (crew) have not been found. Please pray so that my wife Dylan (Dylan Sahara) will be found soon.

“The rest are thankfully safe although suffering from injuries and broken bones. Please pray so my wife Dylan, Andi and Herman and Ujang can be found soon.”

Speaking to local media, he described the total horror that he witnessed in the moments directly after the tsunami, and said the evacuation of the area is proving to be slow.

Ifan said:

“Most of us, I and our manager are on the shore, including myself, when I was thrown into the middle of the sea, there were probably around 20 to 24 corpses around me.

“Evacuation is very slow because there are many roads cut off and bad weather, heavy rain.”

According to reports, the tsunami has already claimed the lives of almost 300 people.

Our thought are with all those affected.
