When does spring start? There was a problem. The researchers imagined a new system in which people could set their own threshold for alerts, based not on the actual magnitude of the quake, but on how violent the tremors would be at their location. Algorithms to characterize the earthquake source must process large volumes of data in real-time to determine when and where an alert should be issued. Not according to biology or history.
