Bid to halt extreme rainfall
INDONESIAN authorities seeded clouds, trying to prevent further rain and flash floods after deluges that hit the country’s Sumatra Island over the weekend left at least 58 people dead and another 35 missing.

Monsoon rains triggered a landslide of mud and cold lava from Mount Marapi, eventually causing rivers to breach their banks. The deluge tore through mountainside villages in four districts in West Sumatra province just before midnight on Saturday.

The floods swept away people and 79 homes and submerged hundreds of houses and buildings, forcing more than 1,500 families to flee to temporary government shelters, according to National Disaster Management Agency spokesperson Abdul Muhari.

He said that 58 bodies had been pulled from mud and rivers by yesterday, mostly in the worst-hit Agam and Tanah Datar districts, while rescuers are searching for 35 people who are reportedly missing. About 33 villagers were injured.

Indonesia’s Meteorology, Climatology and Geophysics Agency head Dwikorita Karnawati has said that more downpours were forecast for West Sumatra in the coming days, and that the danger of extreme rainfall would continue until next week.

Karnawati said an air force plane was sent up to shoot salt flares into the clouds yesterday, in an attempt to get the clouds to release water and break up before they reach the devastated areas in Agam, Tanah Datar, Padang Panjang, Padang Pariaman as well as Padang city, the provincial capital.

The method is known as cloud seeding and creates precipitation, thereby modifying weather.

Indonesia’s air force teamed up with the country’s technology agency to carry out three rounds of cloud seeding yesterday, Karnawati said, adding that more would take place as needed. About 15 tons of salt have been prepared for the action.

Indonesia’s technology agency, known as BPPT, said in a statement that all rain clouds moving towards the four West Sumatra’s districts will be shot with sodium chloride, or salt.

“We are deploying weather modification technology starting tomorrow so that rain does not fall during this emergency response period,” National Disaster Management Agency chief Suharyanto, told reporters on Tuesday.

He spoke while visiting the district of Agam and said that the emergency response will end on May 25. — AP
