CARITA BEACH, Indonesia — The deadly tsunami struck in the dark, without warning.
At least 222 people were killed as waves smashed into houses, hotels and other beachside buildings Saturday night along Indonesia's Sunda Strait, in a disaster that followed an eruption and possible landslide on Anak Krakatau, one of the world's most infamous volcanic islands.
More than 800 others were injured and dozens were reported missing after the tsunami hit coastal areas along western Java and southern Sumatra islands at 9:27 p.m. Saturday amid a Christmas holiday weekend, the Disaster Management Agency said. The death toll could increase once authorities hear from all stricken areas.
It was the second deadly tsunami to hit Indonesia this year, but the one that killed more than 2,500 people on the island of Sulawesi on Sept. 28 was accompanied by a powerful earthquake that gave residents a brief warning before the waves struck.
On Saturday night, the ground did not shake beforehand to alert people to the oncoming wave that ripped buildings from their foundations in seconds and swept terrified concertgoers on a popular resort beach into the sea.
Azki Kurniawan, 16, said his first warning about the tsunami was when people burst into the lobby of the Patra Comfort Hotel shouting, "Sea water rising!"
Kurniawan, who was undergoing vocational training with a group of 30 other students, said he was confused because he had not felt a big earthquake. He said he ran to the parking lot to try to reach his motorbike but discovered it was already flooded.
"Suddenly, a 1-meter [3.3-foot] wave hit me," he said, his eyes red and swollen from crying. "I was thrown into the fence of a building about 30 meters [100 feet] from the beach and held onto the fence as strong as I could, trying to resist the water, which felt like it would drag me back into the sea. I cried in fear ... 'This is a tsunami?' I was afraid I would die."
Dramatic video posted on social media showed the Indonesian pop band Seventeen performing under a tent on popular Tanjung Lesung beach at a concert for employees of a state-owned electricity company. Dozens of people sat at tables while others swayed to the music near the stage as 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, tossing the band and its equipment into the audience.
The group released a statement saying their bass player, guitarist and road manager were killed, while two other band members and the wife of one of the performers were missing.
"The tide rose to the surface and dragged all the people on site," the statement said. "Unfortunately, when the current receded, our members were unable to save themselves while some did not find a place to hold on."
Disaster agency spokesman Sutopo Purwo Nugroho said 222 deaths had been confirmed and at least 843 people were injured.
The worst-affected area was the Pandeglang region of Java's Banten province, which encompasses Ujung Kulon National Park and popular beaches, the agency said.
Indonesian President Joko "Jokowi" Widodo expressed his sympathy and ordered government agencies to respond quickly to the disaster.
U.S. President Donald Trump tweeted support for Indonesia: "We are praying for recovery and healing. America is with you!"
