Tsunami set off by volcanic eruption kills at least 200 in Indonesia

A tsunami believed to be triggered by a volcanic eruption has killed at least 222 people in Indonesia during a busy holiday weekend, sweeping away hotels, hundreds of houses and a group of people attending a beach concert.

More than 800 people were reported injured after the tsunami hit around the Sunda Strait at 9.27pm on Saturday, the Disaster Management Agency said.

At least 28 others were missing, but the toll could continue to rise because some areas had not yet been reached.

Scientists including those from Indonesia’s Meteorology and Geophysics agency said the tsunami could have been caused by undersea landslides or those occurring above sea level on the Anak Krakatau volcano’s steep outside slope following the eruption.

The volcano’s name translates to “Child of Krakatoa”, a volcanic island formed over years after one of the largest eruptions in recorded history occurred at the Krakatoa volcano more than a century ago. The scientists also cited tidal waves caused by the full moon.

Dozens of people sat listening at tables covered in white cloths while others bobbed to the music near the stage as bright strobe lights flashed and theatrical smoke was released.

A child could also be seen wandering through the crowd. Seconds later, with the drummer pounding just as the next song was about to begin, the stage suddenly heaved forward and buckled under the force of the water, throwing the band and all their equipment into the audience.

The group released a statement saying their bass player, guitarist and road manager were found dead, while two other band members and the wife of one of the performers remained missing.

“The tide rose to the surface and dragged all the people on site,” the statement said. “Unfortunately, when the current receded our members are unable to save themselves while some did not find a place to hold on.”

“I had to run, as the wave passed the beach and landed 15-20m inland,” Norwegian Oystein Lund Andersen wrote on Facebook.

The self-described photographer and volcano enthusiast said he was taking pictures of the volcano when he suddenly saw a big wave come toward him.

“Next wave entered the hotel area where I was staying and downed cars on the road behind it,” he wrote. “Managed to evacuate with my family to higher ground (through) forest paths and villages, where we are taken care of (by) the locals. Were unharmed, thankfully.”

The worst-affected area was the Pandeglang region of Java’s Banten province, which encompasses Ujung Kulon National Park and popular beaches, the disaster agency said.

Agency spokesman Sutopo Purwo Nugroho said 222 deaths had been confirmed and at least 843 people were injured. Rescue workers were still trying to access other affected areas.

Indonesian President Joko “Jokowi” Widodo expressed his sympathy and ordered government agencies to respond quickly to the disaster.

“My deep condolences to the victims in Banten and Lumpung provinces,” he said. “Hopefully, those who are left have patience.”

In the city of Bandar Lampung on Sumatra, hundreds of residents took refuge at the governor’s office. At the popular resort area of Carita Beach, some survivors appeared lost.

He said he was confused because he did not feel an earthquake, but ran to the parking lot to try to reach his motorbike. By the time he got there, it was already flooded.

“Suddenly a one-meter wave hit me,” he said. “I fell down, the water separated me from my bike. I was thrown into the fence of a building about 30 meters from the beach and held onto the fence as strong as I could, trying to resist the water, which feels like it would drag me back into the sea. I cried in fear. … ‘This is a tsunami?’ I was afraid I would die.”

The 305-metre-high Anak Krakatau volcano, located about 200 kilometers (124 miles) southwest of Jakarta, Indonesia’s capital, has been erupting since June. In July, authorities widened its no-go areas to two kilometres from the crater.

However, Anak Krakatau remains much smaller than Krakatoa when it blew in 1883, killing more than 30,000 people.

Krakatoa launched far-reaching tsunamis and created so much ash, day was turned to night in the area and a global temperature drop was recorded.

The violent explosions sank most of the island into the volcanic crater under the sea, and the area remained calm until the 1920s, when Anak Krakatau began to rise from the site.

It continues to grow each year and erupts periodically.

He said it is possible for an eruption to trigger a landslide above ground or beneath the ocean, both capable of producing waves.

“Actually, the tsunami was not really big, only one meter,” said Mr Prasetya, who has closely studied Krakatoa. “The problem is people always tend to build everything close to the shoreline.”

Nine hotels and hundreds of homes were heavily damaged. Broken chunks of concrete and splintered sticks of wood littered hard-hit coastal areas, turning beach getaways popular with Jakarta residents into near ghost towns.

Vehicles tossed by the waves remained belly up in the rubble or were lodged in the air under collapsed roofs. Debris from thatch-bamboo shacks was strewn along beaches.

In September, more than 2,500 people were killed by a quake and tsunami that hit the city of Palu on the island of Sulawesi, which is just east of Borneo.

Saturday’s tsunami rekindled memories for some of the massive magnitude 9.1 earthquake that hit on Dec. 26, 2004.

It spawned a giant tsunami off Sumatra island in western Indonesia, killing more than 230,000 people in a dozen countries — the majority in Indonesia.

Roads and infrastructure are poor in many areas of disaster-prone Indonesia, making access difficult in the best of conditions.
