The era of big data for many friends is still erratic, is still at a loss. But a new American invention shows you the future and power of big data. A software app called quakealert can let you know that an earthquake is about to happen 30 seconds in advance.
30 seconds sounds like a little short, but it's very helpful for earthquake escape. Just imagine that 30 seconds can definitely help you shuttle between life and death. This is an early earthquake warning software developed by the US government.
Quakealert calculates earthquakes through cloud data. The app is free and comes with a piece of hardware that can be placed at home or in the office. Shaking means an earthquake is imminent.
