Lunar Seismic Shakemap

Shallow moonquakes, like earthquakes, are expected to cause significant ground motion as seismic wave radiate outward from the source. This seismic shakemap shows the expected round motion for a slip event on a thrust fault (red line) associated with the Mandel’shtam scarp. The shakemap showing peak vertical acceleration for a moonquake of magnitude 6.36 Mw hypocenter at a depth of 350 m. Shades of blue, green, and white indicate areas where shaking is strong.  The regional topography is shown by the white contour lines (500 m contour interval). University of Maryland/Smithsonian
