SEMINAR - Eric Dunham
Earthquake Modeling: From Fault Friction to Seismic Hazard

Earthquakes occur when the two sides of a fault slip in response to a rapid weakening of the fault's frictional strength. In this talk, I will discuss some of the physical processes occurring within the fault zone during seismic events (e.g., shear heating of pore fluids, poroelastic response to compressional or extensional stresses, melting of microscopic frictional contacts) and computational models that simultaneously solve for the transport of fluid and energy in the fault zone together with the elastodynamic response of the rocks surrounding the fault. I will also discuss how dynamic earthquake models are in the process of changing seismic hazard analysis.

Im a phd student at earthquake seismology in Iran. As Im working on similar subject, this seminar was very interesting and helpful for me.Thanks for publishing it here. Its kind of you to send me the full video of Dr Dunham's seminar via my email. I can not get it online from the web because of the low quality of internet in Iran.
