JAKARTA, Indonesia - Hours of heavy rain triggered landslides Wednesday that killed at least 51 people in western Indonesia, a rescue official, while floods inundated other parts of the country.

The deaths occurred in several districts on the main island of Java after more than 12 hours of nonstop rain, local search and rescue chief Eko Prayitno said.

The landslides occurred on the third anniversary of the Asian tsunami, which killed some 160,000 people in Indonesia. Those deaths occurred on Sumatra island, far from Java. The landslides did not disrupt a tsunami warning drill held on Java to coincide with the anniversary.

“At least 51 victims have been buried, but the numbers could still rise,” Prayitno said of the landslides. El-Shinta radio station said 61 people had been killed.

Prayitno said rescue workers were trying to get heavy lifting equipment to the affected villages, but were being hampered roads blocked by landslides.

Seasonal rains and high tides in recent days have caused widespread flooding across Indonesia, where millions of people live in mountainous regions and near fertile flood plains close to rivers.

On Wednesday, floods were reported in numerous locations elsewhere on Java, as well as Sumatra and Sulawesi islands. Thousands of homes were affected, witnesses and media reports said.
