CEEN 545 - Lecture 7 - Attenuation Relationships

This lecture introduces how recorded ground motions can be used to develop empirical ground motion prediction models (called attenuation relationships or ground motion prediction equations). These models can be used to predict the ground motions at a give site due to some scenario earthquake event. The basics of attenuation relationships are reviewed. The Next Generation Attenuation Relationship (NGA) models are briefly introduced and discussed.

This is beyond amazing.
Thanks for your generosity.

Wow! Thank you very much for this lecture!

haha, hanging and footwall are mining terms (and geology). Imagine a tunnel through the fault, the miner would hang his lamp from the hanging wall, and he would be standing on the footwall (his feet are on the footwall).

Can i use these attenuation relationships for a landslide debris, i have Vs30 for the site and i know the nearby fault characteristics. Is this enough to develop an empirical ground motion prediction model for my debris? What could be the best GMPEs weight criteria in such case? Thanks
