The Seismicity Viewer is a Java program for interactive viewing of earthquake locations in a 3D space.

Seismicity Viewer displays earthquake locations in 3D as probability density functions (PDFs), maximum-likelihood hypocenters, Gaussian expectation hypocenters and Gaussian confidence ellipsoids. Station locations, associated P and S residuals, and geographic and geologic features are also displayed. The 3D image can be interactively rotated, zoomed and viewed along the coordinate axes in perspective or orthographic projections. The events can viewed individually, all together, or sequentially as an animation.

Seismicity Viewer can read earthquake location data over the internet.
