5/27/2020 Stereonet Plotting Program
The process of plotting and interacting with the stereonet is important. In developing my software, I have tried to digitize that interactive experience: you have planes that you can create by clicking and dragging, not just by entering in a spreadsheet.

Stereonet 9 brings location and date tagging of individual measurements as well as a free form notes field. Points with location data can be plotted on a Google satellite (or terrain or roadmap) image right in the program. This version of Stereonet is compatible with all modern operating systems and has a modern user interface which has been modeled after. It can read and write older Stereonet text files but has a new binary format for its native file.Stereonet 9 for Macintosh uses the modern Mac OS X “Cocoa” architecture. The Macintosh version is being made available here for those users who need binary file compatibility with the Windows version. Stereonet 9 for Macintosh does not have the nifty 3D viewing of OSXStereonet, but does have Google satellite visualization.

Stereonet 9 requires Mac OS X 10.7 (Lion) or higher. For long term viability of your data, however, you should still export any work as text files which will always be readable by a large number of programs.A comprehensive manual is included with the zip archive.
For Mac Users still on Mac OS X 10.5 and lower (Leopard, Tiger, etc.), you can download a Carbon version of Stereonet. Note that this version will not be kept up to date with the above Cocoa version. Version History Version 9.3.0 — 2015.05.13. Major improvements to the Rose diagram functionality, including:.
Scale the petals by either length or area (new). Only length was possible before. Calculation of the mean direction for axial data (i.e., data with no directional significance). This is sometimes referred to as Krumbein’s (1939) mean. Half circle rose diagrams always show Krumbein’s mean; full circle diagrams can either depict vector azimuths or, if “treat data as axes” is checked in the Inspector, the full circle diagrams will be symmetric (this has been a highly requested feature that I’ve resisted until now!). Addition of a Von Mises Distribution option to the Calculations menu which displays the same 2D azimuthal statistics as the Rose diagram displays.
The program now calculates the circular variance, kappa, and 1 sigma standard error for azimuthal data. Plots wil polar grids can now be saved as.pdf and.svg files. Fixed a bug that occurred when planes were being entered in “DD” format and the data details window was opened.

Authors:and Peter J. HaeusslerUsage:View earthquake focal mechanism symbols three dimensionallyPlatform:WindowsInterface:ArcScene® 9.xInput:A GIS point dataset of earthquake locations containing strike, dip, and rake values for a nodal plane of each earthquakeDownload:3D Focal Mechanisms is a tool for viewing earthquake focal mechanism symbols three dimensionally. This tool operates within the Environmental Systems Research Institute (ESRI®) GIS software ArcScene® 9.x. The program requires as input a GIS point dataset of earthquake locations containing strike, dip, and rake values for a nodal plane of each earthquake.
Other information, such as depth and magnitude of the earthquake, may also be included in the dataset. By default for each focal point, 3DFM will create a black and white sphere or “beach ball” that is oriented based on the strike, dip, and rake values. If depth values for each earthquake are included, the focal symbol will also be placed at its appropriate location beneath the Earth’s surface. 3D Velocity Modeling Author:Cliff ThurberPlatform:Unix, MacDownload:Fortran code (VMS compatible) for 3-D velocity model determination and hypocentral location with local earthquake data. Full inversion, not tomography, this is the program written by Cliff Thurber and modified by others. Author:Usage:Analyze strainmeter data in order to estimate tidal coefficients and pressure admittancePlatform:Unix and/or Mac OS X (Requires Fortran compiler for Mac OS X)Interface:Command lineInput:Time series of strainmeter dataOutput:Cleaned-up strainmeter dataDocs:Online documentation:Download:Cleanstrain+ is a program to process strainmeter data. This code will simultaneously estimate the tidal constituents, pressure admittance, offsets, rate changes, and other terms using least-squares but, importantly, incorporating the temporally correlated nature of strain data (that is, the power spectra is red).
CLUSTER2000 Author:Paul ReasenbergUsage:Identify clusters (e.g., aftershocks) in an earthquake catalogPlatform:Unix, or any platform with FortranInterface:Parameters read from standard inputInput:Catalog text fileOutput:Several text filesDownload:(35k), (233b)CLUSTER2000 recognizes clusters in space-time in an earthquakecatalog. It is intended for use in removing aftershocks or'declustering' the catalog. The methods used aredescribed in 'Second-Order Moment of Central CaliforniaSeismicity, 1969-1982' (P. Reasenberg, JGR v.90., pp.5479-5495,1985). The current version (CLUSTER2000x) reads catalogs ina variety of standard formats.

However, it is not fully Y2000compatible.
