Focal Mechanism Plots, Tables and Other Compilations

The following link provides tabulations of all solutions, continental and regional maps of focal mechanisms, orientations of pressure-, tension- and maximum compressive-stress axes. The tabulations include a convenient CSV format and also a KMZ file for use with GoogleEarth.

  • Focal mechanisms plots and tables

    • Individual Focal Mechanism Details by Year

    Magnitudes

    A detailed compilation of the computed ML and mLG and the relation to Mw is given in the link: Magnitude Study

    This page was revised on September 30, 2014 to place the individual years into separate html files. This was because while traveling I noticed that the download took too long because of the many entries. Hopefully the download will be faster by linking to individual years.
