Indonesian rescuers and villagers have been using their bare hands to try to reach those buried in landslides caused by Wednesday's 7.0 magnitude earthquake.
The official death toll stands at more than 50, but with dozens of people still trapped under the rubble, officials fear that number will rise.
The rescue effort has been hampered by damaged roads and poor weather conditions, which have made it difficult to get heavy digging equipment into the worst-hit areas.
West Java was worst hit by the earthquake, whose epicentre was 115km (70 miles) from Java's south coast at a depth of about 50km.
The quake was felt as far north as the capital, Jakarta, where hundreds of people rushed into the streets from offices and shops.
Officials say at least 18,000 buildings have been damaged in West Java, and some remote villages buried by landslides.
Around 5,000 people made homeless by the quake have sought refuge in make-shift shelters. Many spent the night outside for fear of further aftershocks.
