A month after the perfect storm

screencap from unosat
A month after Haiyan-Yolanda, the Tacloban mayor is still hurt by the criticisms he got from Pnoy. words. The mayor said Pnoy should have first come to the aid of the city before criticizing how his city government dealt with the storm. 

Aside from the strength of the storm, many factors impact the level of devastation to an area. One is the distance from the storm's direct path. Another is the physical geography, topology, and elevation. We cannot change these natural and physical characteristics in several days before the storm.

Another factor that might affect the impact would be the population and population density. And lastly, the preparations for the storm. I am sure someone will come up with some measure how each of these factors contributed to the amount of destruction each place got.

Judging from the UNOSAT map of the typhoon's path, Ormoc, Bogo, and Guiuan are nearer to the typhoon's path than Tacloban. Using population density and elevation data available from the Internet, Bogo and Kalibo have lower elevation than Tacloban. Kalibo and Roxas also have larger population density than Tacloban. Bantayan Island's population density approximates that of Tacloban, but Bantayan's death count is lower. 

Further on, I hope the NDRRMC can come up with numbers on Yolanda deaths per 1000 population of each LGU. There are places that incurred minimal casualties when people listened to warnings from their authorities. I hope people would now listen to warnings given by authorities, that is, if local authorities are doing their jobs.
