The tsunami in Indonesia killed at least 373 people and injured more than 1,400 on the islands of Java and Sumatra, an official said on Monday.
"1,459 people are injured, while 128 remain missing," Sutopo Purwo Nugroho, a spokesman for Indonesia's disaster mitigation agency, said in a statement.
Survivors of the tsunami received aid from community and religious groups but not yet from the government, a neighbourhood chief in the town of Labuan, Pandeglang, told Reuters.
People searched through the debris of collapsed houses as aid posts were set up in the coastal town, part of the worst-affected area on Java's west coast.
Rescuers using heavy machinery and their bare hands searched through debris, pulling out bodies in the worst-affected areas on the west coast of Java island, where and hundreds of soldiers and volunteers looked for victims along a 100 km (60 miles) stretch of shore.
President Joko Widodo visited the affected area on Monday and praised the authorities for swift action in responding to the latest disaster.
Social media footage showed how the tsunami washed away an outdoor stage where Indonesian rock band Seventeen was performing for about 200 guests at a party for utility company Perusahaan Listrik Negara (PLN).
41 PLN employees and their relatives died. At least four band members and support crew were killed, lead singer Riefian "Ifan" Fajarsyah told followers in a tearful post on Instagram.
Dudi Dwiriadi, a district military commander, said personnel and volunteers had been briefed to sweep at least 100 km (60 miles) of coastline in search of victims.
