ShakeMaps, a product of the United States Geological Survey (USGS) Earthquake Hazards Program, are near-real-time maps of ground motion and shaking intensity that are produced following significant earthquakes. They appear as a set of links keyed to areas which have recently experienced an earthquake. 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. Older shakemaps are stored in an archive. The most recent maps are also available as RSS feeds.
