Earthquake rupture parameters are physical measurements that describe how a fault breaks during an earthquake. This includes its dimensions (length, width), the amount of slip (displacement), and the rupture's speed and duration.
They are crucial for accurately determining an earthquake's magnitude, understanding the energy released, assessing seismic hazards, and modeling ground motion, which informs engineering and preparedness efforts.
Seismologists determine rupture parameters by analyzing seismic waves recorded by global networks, using inverse modeling techniques, GPS data, and sometimes satellite imagery (InSAR) to infer fault behavior and slip distribution.
Slip refers to the relative displacement or movement of the two sides of a fault during an earthquake rupture. It measures how much the blocks of crust have shifted past each other along the fault plane.
