Document Summary
Intensity: measure of the effects of an earthquake on people and. To me it could be a lot, but for you it could be: subjective, not measuring anything different. Intensity: measure of the effects of an earthquake on people and infrastructure: magnitude: amount of energy released during an. Maps: shake map earthquake: for a given earthquake, there are several intensity values (depending on the location) but only one magnitude. Intensity map generated automatically in near-real time using data from seismograph stations. Inputs: ground motion data, knowledge of regional geology, output, computed intensity. Intensity reports: maps of georeferenced intensity data, current state-of-the-art. Isoseismal maps: average all the data point, creates a contour map and highlights the heavy shaking is observed, the contour lines represent a change in that intensity, classic display, felt area: Seismic waves are attenuated over short distances: eastern north america. Old, blocky rocks of the continental interior.
