Japan's Earthquake Warning System Interface

Japan’s Earthquake Warning System User Interface.

Here’s how it works

  • Seismometers detect the first shockwave.
  • Computers analyze the wave and estimate how powerful the second one will be.
  • If that wave is estimated to be more powerful than a certain threshold (”lower 5″ on the local scale), an alert is issued.
