DisasterAlert helps you to prepare for an early escape before the infrastructure collapses. This might save your and other's lifes. Sometimes it is crucial to have access to information first. Especially with natural (or even human made) disasters it is often just a matter of minutes to know where and when something happened. No matter if an earthquake happened and a tsunami is incoming or there is a tropical cyclone right next door, it is good to know first.
DisasterAlerts shows you the distance from your current postion to the disaster area. So you always know which news are relevant for you.
