Indonesia deploys helicopters with disinfectant to reduce risk of diseases after tsunami

Indonesia's disaster agency says helicopters are dropping disinfectant on neighbourhoods in the earthquake- and the tsunami-stricken city of Palu to reduce disease risks from the thousands of victims believed buried in obliterated communities.

The agency said Thursday that 430 hectares (1.7 square miles) of land and nearly 3,500 homes succumbed to liquefaction when the Sept. 28 earthquake turned the soft soil to mud.

Spokesman Sutopo Purwo Nugroho said in a statement the disinfectant is necessary because of a large number of victims not recovered by the search and rescue effort that ended on October 12.

Officials say the destroyed Palu neighbourhoods of Balaroa and Petobo, and Jono Oge in neighbouring Sigi district, cannot be redeveloped. Balaroa and Petobo will be turned into green spaces with monuments to those who perished.
