Introduction to Afterslip Modelling: Understanding Rate and State Friction Laws

This meeting introduces afterslip modelling in postseismic studies following major earthquakes like the 1997 Manyi Earthquake and the 2009 L’Aquila Earthquake. Learn about afterslip, modelling techniques, and examples from literature.

  1. Afterslip Modelling Meeting 1 of 4 Introduction to Rate and State Friction laws

  2. Why are we here? • Many of the postseismic studies I am looking at could involve afterslip modelling • Events I intend to study include • 1997 Manyi Earthquake (7.6) • 1996 Earthquake de Tim (western Tibet) (6.9) • 2009 L’Aquila Earthquake (6.3) • 1997 Zirkuh Earthquake (7.7?)

  3. Afterslip – what is it? • Slip on the fault plane (or extend of it with depth and laterally) which is not associated with seismic moment release • Model using elastic dislocation theory • Basically same as a slip distribution for coseismic event. The size of slip patches is currently chosen arbitrarily.

  4. Initial Results from Manyi

  5. Initial Results from L’Aquila

  6. Examples from Literature • Landers • Hector Mine • Izmit (early signal) • Manyi (early signal) • Chi-Chi

  7. Friction • The A-level approach • Block Sliders
