REPUBLIKA.CO.ID, JAKARTA -- The La Nina weather anomaly is one of the major causes of several natural disasters that occurred in Central Java lately, according to the Indonesian National Disaster Mitigation Agency (BNPB).

"The anomaly led to an above normal rise in the surface temperature of the waters of West Indonesia and triggered the flow of wet air from the oceans," the agency's spokesperson, Sutopo Purwo Nugroho, stated here on Monday.

The agency has called on all regional mitigation agencies to increase their awareness regarding forecasted disasters, such as floods, landslides, and tornadoes.

Meanwhile, thousands of houses in West, Central, and East Java were reportedly inundated by floods on Sunday, June 19.
