Earthquake Warning

With all the talk of earthquakes, in the 2000s I designed an earthquake detector. It relies on the detection of P-waves and S-waves. For example in the Tulbagh quake, it would have given 20+ seconds' warning in the city of Cape Town. If there were a Koeberg quake, it would give about 7 seconds' warning in the city. UC Berkeley claim that they have new technology to warn of earthquakes. This one will do more or less the same. Divide kilometres from the epicentre by five, to obtain the warning time in seconds.
