PANDEGLANG: A tsunami killed at least 222 people and injured hundreds on the Indonesian islands of Java and Sumatra following an underwater landslide believed caused by the erupting Anak Krakatau volcano, officials and media said.

Hundreds of homes and other buildings were “heavily damaged” when the tsunami struck, almost without warning, along the rim of the Sunda Strait late on Saturday, Sutopo Purwo Nugroho, spokesman for the disaster mitigation agency, said.

Thousands of residents were forced to evacuate to higher ground. By 1040 GMT, the disaster agency had raised the death toll to 222 from 168, with 843 injured and 28 missing.

TV images showed the seconds when the tsunami hit the beach and residential areas in Pandeglang on Java island, dragging with it victims, debris, and large chunks of wood and metal.

Asep Perangkat, who fled Carita beach Saturday night, said he was with his family when the wave surged through the town, carving a path of destruction.

“Cars were dragged about 10 metres and so were containers,” Perangkat told AFP.

“Buildings on the edge of the beach were destroyed, trees and electric poles fell to the ground.

“All the residents that are safe ran to the forest,” he said.

In Lampung province, on the other side of the strait, Lutfi Al Rasyid said he fled the beach in Kalianda city in fear for his life.

“I could not start my motorbike so I left it and I ran… I just prayed and ran as far as I could,” the 23-year-old told media.

Initial error

Authorities say the tsunami may have been triggered by an abnormal tidal surge due to a new moon and an underwater landslide following the eruption of Anak Krakatoa, which forms a small island in the Sunda Strait between Java and Sumatra.

“The combination caused a sudden tsunami that hit the coast,” Nugroho said, but added that Indonesia´s geological agency was working to ascertain exactly how it happened.

He added that the death toll would likely increase.

Video footage posted to social media by Nugroho showed panicked residents clutching flashlights and fleeing for higher ground.

Indonesian authorities initially claimed the wave was not a tsunami, but instead a tidal surge and urged the public not to panic.

Nugroho later apologised for the mistake on Twitter, saying because there was no earthquake it had been difficult to ascertain the cause of the incident early on.

“If there is an initial error we´re sorry,” he wrote.

The wave swamped parts of the coast around the Sunda Strait, but was most damaging in Pandeglang district, on Java´s western tip, where at least 33 people died and 491 people were injured.

Three people died further north in Serang, while seven were killed in South Lampung, on Sumatra island.

Heavy equipment was being transported to badly-hit areas to help search for victims, Nugroho said, adding evacuation posts and public kitchens were being set up for evacuees.

Abu Salim, a member of the Tagana disaster volunteer group, said he helped evacuate victims in Banten province.

“We evacuated the victims who died and were injured, we took them to health clinics … Most of them suffered from broken bones,” he said, adding he feared more were missing.

Although relatively rare, submarine volcanic eruptions can cause tsunamis due to the sudden displacement of water or slope failure, according to the International Tsunami Information Centre.

Anak Krakatoa is a small volcanic island that emerged from the ocean half a century after Krakatoa´s deadly 1883 eruption which killed more than 36,000 people.

According to Indonesia´s geological agency, Anak Krakatoa had been showing signs of heightened activity for days, spewing plumes of ash thousands of metres into the air.

The volcano erupted again just after 9:00 pm on Saturday, the agency said.

An eruption just before 4:00 pm on Saturday lasted around 13 minutes and sent plumes of ash soaring hundreds of metres into the sky.

Indonesia, one of the most disaster-prone nations on earth, straddles the so-called Pacific “Ring of Fire”, where tectonic plates collide and a large portion of the world´s volcanic eruptions and earthquakes occur.

Most recently in the city of Palu on Sulawesi island a quake and tsunami in September killed thousands of people.

On December 26, 2004 a tsunami triggered by a magnitude 9.3 undersea earthquake off the coast of Sumatra in western Indonesia killed 220,000 people in countries around the Indian Ocean, including 168,000 in Indonesia.

Anak Krakatoa is one of 127 active volcanoes which run the length of the archipelago.
