*"**Why use seismology to study landslides and debris flows?**"*

*Kate Allstatdt*
*USGS, Geologic Hazards Science Center*

Landslides and debris flows generate seismic signals that contain valuable
information about the event as it unfolds. The incorporation of seismic
analysis into more traditional investigations of surface mass movements can
add a new dimension to our understanding of event dynamics and the hazards
these events pose. However, successfully harnessing the seismic wavefield
to make scientific advances requires that we understand what information is
actually contained in the observed wavefield and also that we have the
means to reliably extract it. Though this subdiscipline of seismology is
only a few decades old, the research community has already made strides in
establishing the theory, models, and methods required to use seismology to
make quantitative observations, but outstanding challenges remain. I will
review the progress that has been made, giving particular focus to what we
are learning from 1) large-scale seismic experiments at the USGS debris
flow flume and 2) multidisciplinary studies of impactful landslide
sequences in which seismic analysis is just one of many tools in a diverse
toolkit. I will also discuss bigger picture motivations for the pursuit of
landslide seismology, such as the search for reliable precursors and early
warning systems. I will end with a discussion of how I have incorporated
aspects of landslide seismology into GeoGirls, a geology and technology
fieldcamp for middle school girls at Mount St. Helens.
