>>6359638As far as I'm aware, there isn't much in the way of preemptive detection of an earthquake though, apparently there is a device that is said to detect the early signs of the earthquake. Otherwise, everything I've hard of on the subject is just detecting where the origin is and measuring the size of it. I may be wrong about early detection though.
