earthquake at different intensities of shaking and distances from the fault. First, I gathered real
earthquake footage from around the world. I attempted to ascertain exactly where the earthquake
footage was taken in relation to the earthquake source. Then, I matched the footage location as
precisely as I could to an intensity level on the USGS ShakeMap for the earthquake. Next, I
matched the shaking intensity for the footage location with the intensities of the M7.8 scenario
ShakeMap. The ShakeOut Scenario earthquake produces intensity levels IX & X near and far from
the fault, and the types of seismic waves that cause these levels of intensity are of different
frequency and duration. I wanted to capture all this variation. I obtained a lot of earthquake
footage that depicted close-to-the-fault, high-frequency, short-duration shaking that resulted in
intensity levels of IX & X, which I matched to near-fault locations in the ShakeOut Scenario. I also
obtained earthquake footage that demonstrated low-frequency, long-duration shaking that resulted
in intensity levels of I & II, which I matched to far off locations for the Scenario. However, footage
taken far from the fault rupture that demonstrated low-frequency, long-duration seismic shaking
of intensity levels of IX & X was very difficult to secure. After collecting and interpreting footage, I
used Google Earth Pro and iMovie to bring it all together. Assisted Perry-Huston, I created a flyby
movie in Google Earth Pro and edited it in iMovie, incorporating and narrating the earthquake
footage I had collected from the Internet. This produced an accurate depiction of types of shaking
that can be expected at various locations in the M7.8 Scenario earthquake. A future step will be to
create an on-line database of the footage that includes earthquake parameters.
