Indeed, for most Filipinos the most striking memories of tropical storm Sendong, which rampaged across eastern to northwestern Mindanao last December 16 and 17, are the images of the death and destruction left in its wake. Nothing transmitted the sheer devastation caused by the floods that hit Cagayan de Oro and Iligan Cities more powerfully than the photographs of muddied corpses, flattened houses, weeping parents and orphaned children wandering dazedly among the wreckage.

Where trees and villages had been, only mud, fallen logs and debris were left. And where a community of gated houses once stood, only crushed vegetation,

twisted metal and shattered concrete remained. The group’s written report describes it thus: “The 250-350 mm of rain dumped in the watershed of Mandulog River during tropical storm Sendong and the location of the communities in the lowland floodplains was a perfect mix for a disaster.
