Whereas static stress drop provides hints on the scaling of the static parameters (such as source size or final displacement) characterizing an earthquake, dynamic stress drop is the stress that is effectively available to drive fault motion and, as such, a key parameter in the estimation of strong ground motion, as it influences the high‐frequency level of acceleration (Brune, 1970, 1971). There are many methods for simulating ground motion from earthquakes. Each has particular strengths, and each can provide estimates of ground motion. However,...
