Geomorphology Brown Bag - Spring 2011
Tuesday noon to 1 pm in ALS 3096
Geomorphology of Tsunamis

The Japan earthquake and tsunami of March 11, 2011 reminds us of the vulnerability of our own region and coastline to a similar event.

This quarter we will discuss what we know (and what we don't know) about tsunamis. Some possible discussion topics:

1) Tsunami-generating mechanisms
2) Oceanic propagation of tsunamis: spread, fluid dynamics, and bathymetry
3) Rheological changes as the tsunami moves inland (Gordon)
4) Stratigraphy/depositional record of historical tsunamis
5) Human/tsunami interaction
