(Phys.org)—A trio of researchers with Istituto Nazionale di Geofisica e Vulcanologia in Italy has created an earthquake warning system that reliably predicted a series of aftershocks after a major quake in Italy. In their paper published on the open-access site Science Advances, the team describes the system and its accuracy in predicting the series of aftershocks that occurred during 2016 to 2017.
