Japanese innovations have now come out with a new gadget known as EQGuard Home Earthquake Alarm System that warns users 20 seconds before an earthquake strikes, but I do not think that 20 seconds is quite enough to assemble your family and your naughty kids to transport them at safe place.
This new alert system functions by connecting itself with Japan’s government Meteorological Agency, JAMA that monitors seismic activity. Now, to save large number of people from upcoming earthquake the agency is also looking ahead to develop some highly advanced earthquake alert system to make people alert over the internet, via email and even via text message.
No info about price and availability but still crucial warning of upcoming earthquake can help you to save your life.
