This is an interesting KMZ file which enables you to observe earthquake hazards in near real-time ground movement and shaking intensity that are produced during an earthquake. This product was created by the USGS Earthquake Hazard Program. The maps display instrumental intensity (modified Mercalli scale), peak ground acceleration, and peak ground velocity. They are downloadable as image (JPEG) or zipped postscript (PS) files, and datasets are downloadable as text, zipped shapefiles,KML , XML, or HTML files. This program can be helpful to geology students especially students that are new in the program to understand the dynamics involved with earthquakes. Earthquake scales, peak ground acceleration, velocity and potential damage are important to understand.
