[ghsc-seminars] Today @ 2pm - Brandon Dugan, CSM: Submarine Landslides

[Mirus, Benjamin]

*Geomechanics, Fluid Flow, and Submarine Landslides – *
*What We Think We Know and What We Need to Know*

*Brandon Dugan*
*Associate Professor and Baker Hughes Chair*
*Geophysics Department, Colorado School of Mines*

Submarine slope failures occur on low-angle slopes worldwide. Under the
right conditions they can damage seafloor infrastructure and create
tsunamis. We will discuss how we integrate geophysical data, geomechanical
behavior, and process-based modeling to understand these geohazards.
Geophysical techniques help us define the shape, size, and structure of
submarine slides. Geomechanical analyses and experiments help characterize
the rock and fluid properties that determine the strength and stability of
a slope. These data inform numerical models that couple fluid flow,
deformation, and failure and allow us to estimate the role of fluids and
earthquakes in slope failure. We will conclude by discussing what
additional information we can capture with geological, hydrological, and
geophysical studies, and how this benefits the study of geohazards.

*Tuesday, February 26th**, 2019*
*2-3pm*
*  (Mountain Time)*
*USGS, 1711 Illinois Street, Golden, CO*
