May 29 (UPI) — Geologists have found a possible early signature of massive earthquakes. New research suggests the telltale seismic pattern shows up between 10 seconds and 15 seconds into a seismic event.
Scientists discovered the warning sign after analyzing GPS records of peak ground displacement during dozens of earthquakes. The analysis of several GPS databases revealed a point in time when the beginnings of an earthquake takes the form of a “slip pulse,” the mechanical functions of which scale with magnitude.
The discovery, published this week in the journal Science Advances, allowed scientists to differentiate between small- to medium-sized earthquakes and large to extra-large quakes.
