eQuakes

Allows geologists to examine earthquakes, including properties such as focal plane data and hypocenter distributions. This is most useful in examining patterns of seismicity in tectonically active areas. Data can be analysed in several standard formats, such as produced by the International Seismological Centre, or the Lamont Doherty Earth Observatory Global CMT project. Cross-sections can be produced in arbitrary orientations, and centroid moment tensor data can be analysed interactively using stereographic projections. The sandbox stores parameters and data, so eQuakes is able to start where it left off. Other data are stored at the discretion of the user. eQuakes can now section tomography data using a probabilistic interpolator. This allows precise juxtaposition of earthquake data with tomographic images produced by the Deep Earth Flier.
