Disaster Early Warning Network


We generally credit smartphones for making camera and audiovisual players irrelevant. But we often forget that every smartphone is also, by default, a GPS receiver. Quite correct, if not precise, latitude and longitude of the device is being instantaneously updated and displayed. This standard feature is embedded in every smartphone regardless being Android or iOS. It has prompted Battalgazi Yildirim, a (literally young Turk) geophysicist from Stanford, developing a mobile-based IoT application named Zizmos for earthquake’s early warning system.
It was not all sunshine and fare weather that greeted us on the December 26th this year in Sri Lanka. Instead a country in a crisis dealing with the continuous week long rains washing away sides of hills and flooding (copy of Dec 26th landslide and flood warnings issued by DMC). While we were at the Hambantota exhibition, there was uncertainty in being cut-off from Colombo with flash floods crossing roads in various E/A/B network. Had the rains continued on the 26th we may have been stranded or had great difficulty returning to Colombo. An incident or situational map, like Google’s Alerthub, would have been informative in comforting the uncertainties.
