Seismicity Viewer version 5.03D seismicity visualization toolAnthony Lomax - Anthony Lomax Scientific Software |
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.
Version 5.0 includes:
Other features:
- Configurable plotting of latitude/longitude grids and many more enhancements to plotting elements (see Help->Help->Running,arguments
- Plotting of rays on focal sphere
- Auto-scaling, 3D reference axes (rectangluar mode only)
- Interactive interface to create plots with the NLL utility Grid2GMT (UNIX and Linux only)
- global 3D view showing the whole earth, with coastlines and plate boundaries
- (preliminary) support for displaying the NonLinLoc "GLOBAL-mode" regional/teleseismic locations in spherical coordinates
- a search mode to obtain event lists directly over the internet from the "USGS/NEIC (PDE) 1973 - Present", "USGS/NEIC (PDE-Q) Most Recent Events", and the "NOAA Significant Worldwide Earthquakes" catalogs hosted by NEIC
NOTE: due to a change on the NEIC website, to use the search mode you must otain the current version of SeismicityViewer v3.0.0X04 (01Aug2003) see Seismicity Viewer software guide- a new Information Window containing lists of displayed events and event phase data
- plotting of a 2D image file (GIF) as a horizontal surface
- plotting of 3D symbols
- navigation toolbar
- automated saving of snapshots
- plotting of surfaces in 3D
- event display filtering
- focal mechanism display filtering
- variable line widhts
- (preliminary) support for reading and displaying shapefiles (requires shapefile.jar on your Java classpath)
The Seismicity Viewer is written in the Java language. Because it is graphics intensive, the viewer runs best on a recent computer with high performance graphics hardware.
Try the Seismicity Viewer
You can try online these applet Seismicity Viewers (Be patient, the applet and data may take a while to load!):
- examine earthquake locations in a 3D model for Vesuvius Volcano.
- examine global seismicity from 1973 to 2006 in a 3D view of the earth.
- examine the location for the M=4.7 1995 Ventimiglia, France mainshock.
- examine the locations for recent seismicity in the Focal Region of the California Earthquake of April 18, 1906.
Download and install the Seismicity Viewer:

NOTE: due to a change on the NEIC website, to use the search mode you must use a version of SeismicityViewer later than v3.0.0X04 (01Aug2003)
