The Effects of Dynamic Damage on Seismic Radiation from Earthquakes and Underground Explosions

Session ID#: 83235

Session Description:
The effects of dynamic rock fracture on the microscale affect earthquake mechanics and the seismic radiation from earthquakes and underground explosions. The residual fracture damage in a fault zone can affect the dynamics of future earthquakes and the residual damage surrounding a nuclear explosion can affect the coupling of subsequent explosions in the same location.  The recent incorporation of microscale damage in large scale models has increased our understanding of its role in a wide range of applications from seismic hazard assessment to the discrimination of nuclear explosions from earthquakes and estimation of their yield.

This session provides an opportunity for scientists from the fields of earthquake seismology, earthquake source mechanics, fault zone geology and underground nuclear explosion monitoring to share their latest work.
