Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 12811

Session Description:
During shear failure processes, such as earthquakes and landslides, the released potential energy is partitioned into kinetic/radiated seismic energy and energy dissipated by friction and inelastic deformation. Energy partitioning during shear failure is one of the most fundamental but challenging issues that needs to be quantified in order to understand the basic physics of the process. The key controlling parameters for the energy partitioning, such as rupture speed, material strength, stress drop, surface roughness, friction, etc., have been extensively investigated with seismological observations, numerical modeling, structural geology field work, and laboratory experiments of rock mechanics and granular flows at different scales. We welcome submissions from this broad range of disciplines with the intent of establishing what we have observed and understood so far, and to define the key issues to achieve better understanding in the future.
