Two Java-based applications are provided below for visualizing fault-related data. One, based on OpenSHA, allows visualization (and editing if you have write permission) of the database values stored in the Oracle database. The other, a pre-release of SCEC-VDO, allows 3D visualization of the data or models.

Because both applications read data from the Oracle database on the fly, you are required to have Java version 1.5 running on your computer. You can check your version of Java (and update if you have something less than Java 1.5) by following instructions at:



Before describing the applications, a brief explanation of the data/models is in order. The Fault-Section Database contains a list of all fault sections that may be of use (some of which may be mutually exclusive). A Fault Model is simply a list of Fault Sections that represent a complete viable, statewide model (where the slip rates and aseismicity factors in the Fault-Section Database are ignored in the Fault Model). A Deformation Model is simply a Fault Model with Slip-Rate and Aseismic slip factors added (which may or may not be the same as in the fault section database).

When viewing a Fault or Deformation Model in the following applications, all Fault Sections are shown regardless of whether they are used in the model. However, they are not visible (or selectable) if they are not part of the model (i.e., they remain listed only as unchecked boxes). We did this in order to show what was not included in a given model.

The best way to learn these applications is to just play around with them. There are no user manuals, just a few notes after the links for each below.

To run the applications, simply click "Launch with Java Web Start" below. This will automatically download, create shortcuts on your computer, and launch the application. Also, when using Java Web Start, updates will be automatically downloaded as new versions become available.

If you prefer to download a JAR file instead, that option is availble, but you will not recieve automatic updates. To launch a JAR file, simple double click it after downloading. If that doesn't launch the application, try going to a command line and typing:

java -jar [Name of the Jar file]

Please send questions to Ned Field, Kevin Milner, or Peter Powers if you have problems.

After launching you will see an "Authorizing User" window; if you don't have a password just leave this as "Read Only" and click "Login". Hopefully the rest is self explanatory.
