Areas considered are within the Basin and Range physiographic province, namely Arizona, Nevada, and New Mexico. Ground intensity level determinations, formatted as displacement and acceleration, are compared with continental and world-wide averages. A characterization of the physical and theoretical nature of microseismic activity is included. Author
