The death toll from the tsunami that hit Indonesian islands without warning Saturday night has passed 420 with more than 1,400 people injured.
Thousands of people were left homeless when the waves smashed homes on coastal areas of western Java and southern Sumatra.
Indonesia Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said the death toll had climbed to 429 on Tuesday and at least 128 were missing.
Nugroho said more than 16,000 people were displaced and that there was an urgent need for heavy equipment in remote Sumur subdistrict, a hard-to-reach area near Ujung Kulon National Park that experienced heavy damage. Some villages there have been cut off due to damaged roads and bridges, making it difficult to supply aid and help people who may be injured or trapped.
Military troops, government personnel and volunteers were searching along debris-strewn beaches. Where victims were found, yellow, orange and black body bags were laid out, and weeping relatives identified the dead. Chunks of broken concrete and splintered wood littered the coast where hundreds of homes and hotels had stood.
The tragedy changed the mood for local Christmas celebrations, which are traditionally filled with laughter and uplifting music but were replaced by somber prayers for victims of the disaster.
Church leaders called on Christians across Indonesia, the world’s most populous Muslim nation, to pray for victims of the tsunami.
Pastor Markus Taekz said Tuesday his Rahmat Pentecostal Church in the hard-hit area of Carita did not celebrate with joyous songs this year. Instead, he said only about 100 people showed up for the Christmas Eve service, usually attended by double that number. Many congregation members had already left the area for the capital, Jakarta, or other locations away from the impact zone.
“This is an unusual situation because we have a very bad disaster that killed hundreds of our sisters and brothers in Banten,” he said, referring to the Javanese province. “So our celebration is full of grief.”
The waves followed an eruption and apparent landslide on Anak Krakatau, or “Child of Krakatoa,” a volcanic island that formed in the early part of the 20th century near the site of the cataclysmic 1883 eruption of Krakatoa.
Indonesian President Joko Widodo, who faces what promises to be a tough re-election campaign next year, vowed to have all tsunami-detection equipment replaced or repaired.
Nugroho acknowledged on Twitter that the country’s network of detection buoys had been out of order since 2012 because of vandalism and budget shortfalls.
But the head of Indonesia’s Meteorology, Climatology and Geophysics Agency, Dwikorita Karnawati, said the tsunami was likely caused by Krakatoa’s volcanic activity and so could not have been picked up by the agency’s sensors, which monitor conventional earthquakes responsible for more than 90 percent of Indonesia’s tsunamis.
Karnawati said the tsunami was probably caused by the collapse of a big section of the volcano’s slope. Anak Krakatau been erupting since June and did so again 24 minutes before the tsunami, the geophysics agency said. Other scientists have said an underwater landslide may also have contributed to the disaster.
Indonesia, a vast archipelago of more than 17,000 islands and home to 260 million people, lies along the Ring of Fire, an arc of volcanoes and fault lines in the Pacific Basin.
The massive eruption of Krakatoa in 1883 killed more than 30,000 people and hurled so much ash that it turned day to night in the area and reduced global temperatures.
