<p>A system that provides an area warning to a general population of an earthquake prior to the arrival of the hazardous ground motion and of approaching natural disasters that could impact an area. This area advanced warning thereby provides time for users to seek shelter and through automated means to reduce property damage as well as injuries and lives lost. A preferred embodiment of the invention utilizes a plurality of Local Station Detector Sites (60), equipped with earthquake seismic motion detectors (65) and microprocessors (67) designed to almost instantaneously provide a profile of existing ground motion to a Central Processing Site (80) in conjunction with further analysis of similar signals from multiple sites. A warning instruction is then transmitted back to all appropriate Local Station Detector Sites to initiate transmission of local area warnings (70) to a general population of all users in an appropriate and specific geographic area with minimal possibility of false alarms.</p> |
