ABSTRACT: -
Earthquakes and Tsunamis strike without warning. The resulting damage can be minimized and lives can be saved if the people living in the earth quake-prone area are already prepared to survive the strike. This requires a warning before the strong ground motion from the earthquake arrives. Such a warning system is possible because the energy wave released at the epicenter travels slower (at 3.5 to 8km/s) than light, which is the principle behind developing this application.
The warning signal from the earthquake or tsunami epicenter can be transmitted to different places using the satellite communication network, fiber-optics network, pager service, cellphone service or a combination of these. The satellite based wireless network such as ISS is idle if system has to cover a large continent like
