GPS data can detect earthquakes hours before they happen

  The current earthquake warning systems are only able to provide a little window of warning, typically less than two minutes before an earthquakes strikes – and in some circumstances, alerts are only sent out three to five seconds after an earthquake has already begun. Quentin Bletery from the French Côte d’Azur University and Jean-Mathieu Nocquet from the Institut de Physique du Planète in Paris have conducted a new study that may hold the secret to early earthquake detection. Observations of previous earthquakes are used to forecast Currently, it is not possible to anticipate earthquakes; instead, seismic activity in a given area and observations of previous  earthquakes  are used to forecast them. These observations are analyzed and utilized to calculate the probability of seismic activity in the future. As a result, earthquake early warning systems don’t forecast earthquakes; instead, they look for ground motion after one has begun. Upon sensing ground motion, warnin...
