Earthquakes and friction laws Victoria Stevens Scholz 1998

Outline – Friction laws – Stability regimes – Model predictions Stages in seismic cycle Coupling Afterslip – Things model doesn’t explain

Friction Laws

Stability regimes

Stages in seismic cycle Model predictions

Seismic coupling

Model predictions Continental faults fully coupled

Model predictions Coupling controlled by temperature

Model predictions Coupling at subduction zones

Model predictions Afterslip

Things model doesn’t explain Slow earthquakes Tremor Slip transients on all time scales Deep earthquakes different New data – all faults creep, more lateral variation in coupling

Why is reality more complex than the model?
