My professional interests are in relations between the earthquake cycle and long term geological deformation, behavior of natural fault and crack populations, fault-related folding, regional tectonics of South America, interpretation of seismic reflection profiles, energy and climate change, and so on. I have carried out field research in Chile, Argentina, and the western United States for the past 45 years. I recently finished my term on the International Advisory Board for the Chilean National Research Center for integrated Disaster Risk Management. Outside of Cornell, I am a former Board Member of the Chocorua Lake Conservancy.

It includes almost all of the goodness of Stereonet 10 and lots of subtle new tweaks as well (check out the detailed version history, below). This version of Stereonet is compatible with all modern operating systems and has a modern user interface which has been modeled after OSXStereonet for Mac by Nestor Cardozo and me. It can read and write older Stereonet text files, can read the Stereonet 11 binary files, but saves its data in a new binary format. Provide Stereonet Feedback Log4J Note: Stereonet is not written in Java, has no logging mechanism and is thus not subject to the Log4J exploit. Websites that Stereonet may contact by explicit user action (StraboSpot, Google Maps, etc.) may or may not be affected.

It was written to help structural geology professors and students quickly and accurately construct Mohr diagrams so that will have to spend less time plotting and more time exploring the results. The user can enter principal stresses or the complete stress tensor and the program will calculate and plot the results. Likewise, the program can do simple calculations such as how much pore pressure will produce a fracture (i.e., hydraulic fracturing) or what are the range of orientation of planes that will be reactivated under a particular loading condition. The plots produced can be saved as high quality vector graphics in the .svg format.

The program has a revamped, and vastly improved, user interface, includes most of the scientific functionality of the older versions, and will work just fine on modern operating systems such as Mac OS X (“Lion”) and Windows 7. The functionality and interface of the program on the two platforms is identical. The Mac version, shown above, requires Mac OS X 10.7 (Lion) or higher.

It is designed primarily to view, edit and output high quality graphics for Strat Mobile data files, but it can also be used as a stand alone program to build sections from scratch, including calculating thicknesses from field data such as tape measure, Jacob Staff, GPS coordinates of the top and base, etc. Strat Desktop has the following features: Provide Strat Desktop Feedback https://www.rickallmendinger.net/download daily 0.75 2026-01-18 https://images.squarespace-cdn.com/content/v1/5fd3a0dac47b7d485d6715e5/1607794638243-MQVPKT5ML75FED8N3E4N/Structure+Lab+Manual+300+page+1.png Lab Manual - A different kind of lab manual… Structural geology needs a new laboratory manual, so I decided to write one! It is called Modern Structural Practice and it is distributed free of charge (though I hold the copyright). You can download it, and access related programs and files, here. I highly recommend that you read the rationale page to learn why I think a new lab manual is necessary.

The actual numerical methods for calculating eigenvalues are beyond the background of most introductory structural geology students and, while spreadsheet programs like Microsoft Excel™ can calculate them via Visual Basic macros, or using the goal seek tool, doing so is not obvious and can be tedious (and can be subject to macro viruses).

This version is compatible with the latest Mac and Windows operating systems. The program is designed as a teaching and visualization device. As such it can animate progressive deformations, plot particle paths, and provides text access to lengths and angles in all steps of a deformation to allow the user to capture the data and plot it in an external program. As the screen shot below shows, the program can also read text files of digitized objects like fossils for deformation.

You can choose from several different map datums, edit data and have it converted instantaneously to the other format, etc. Additionally, it can calculate all of the coordinates in a single UTM zone, even if the data span several UTM zones. For example, say your data span UTM zones 5 to 9. With this program, you can have the program calculate the coordinates of all data points in, say zone 7 [be careful, however, as data spanning more than about 7 or 8 zone can have seriously negative artifacts when processed this way!]. Finally, the program has a built in world wide map of UTM zones (though it does not plot your data on the map, at least yet). https://www.rickallmendinger.net/program-feedback daily 0.75 2024-10-02 https://www.rickallmendinger.net/contact-me daily 0.75 2022-11-16 https://www.rickallmendinger.net/fault-bend-fold daily 0.75 2021-04-11 https://www.rickallmendinger.net/growth-fault-bend-fold-1 daily 0.75 2021-04-11 https://www.rickallmendinger.net/growth-fault-bend-fold-2 daily 0.75 2021-04-11 https://www.rickallmendinger.net/anticlinal-stack daily 0.75 2021-04-11 https://www.rickallmendinger.net/anticlinal-stack-1 daily 0.75 2021-04-11 https://www.rickallmendinger.net/outofsequence-duplex daily 0.75 2021-04-11 https://www.rickallmendinger.net/listric-normal-fault daily 0.75 2021-04-11 https://www.rickallmendinger.net/domino-normal-faults daily 0.75 2020-12-13 https://www.rickallmendinger.net/chocorua-gallery daily 0.75 2020-12-17 https://images.squarespace-cdn.com/content/v1/5fd3a0dac47b7d485d6715e5/1608053862508-OEVKACGM6C0Q3AUUUN87/IMG_3353.JPG Chocorua, New Hampshire The classic view with white birch https://images.squarespace-cdn.com/content/v1/5fd3a0dac47b7d485d6715e5/1608053860385-PTUXXZ83EB9Q8QANDIOE/IMG_3348.JPG Chocorua, New Hampshire https://images.squarespace-cdn.com/content/v1/5fd3a0dac47b7d485d6715e5/1608053857891-INDZ53YZLUACPSXZV1XS/2007.08.14-078.JPG Chocorua, New Hampshire Mt.

Cardozo, Don Fisher, and I wrote Structural Geology Algorithms: Vectors and Tensors because of our conviction that, to do modern structural geology, students need to be introduced to the powerful linear algebra techniques that underly our science.

Please use the newer, and much better, GMDE Lite instead! Most mobile device field mapping software is excellent for locating the geologist horizontally (in X and Y, longitude and latitude, etc.) but does not bring the third dimension, elevation (i.e., Z), into the picture. However, to do significant calculations that can aid the geologist while in the field, you need X, Y, and Z. GMDE Mobile is one of the first mapping programs to allow the user to load a digital elevation model (DEM) for off-line use in the field. See the Using GMDE in Teaching page for additional information. https://www.rickallmendinger.net/stereonet-mobile daily 0.75 2022-08-30 https://images.squarespace-cdn.com/content/v1/5fd3a0dac47b7d485d6715e5/14914110-0093-457c-afdc-6998f0b4cd1e/IMG_27713951C86D-1.jpeg Stereonet Mobile - Stereonet Mobile Stereonet Mobile is designed to help you collect, visualize, and analyze geological orientation data on the go. It is a companion to my Stereonet program for desktop computers, but it can also be used to measure orientations on the outcrop. The app has the following features: Provide automatic data entry as a geologist's compass by reading the iOS device orientation and converting it to strike and dip of planes and/or trend and plunge of lines. It is the only geology compass app that can record the strike and dip of planes using the sighting method and the device camera. Provide manual data entry via either tapping and dragging on the stereonet or by typing values into text fields Plot one group of lines and one group of planes, though individual observations can be tagged and filtered as the user wishes. Carry out basic calculations such as: rotations about any axis, planes from poles or poles from planes, measure angles between lines and between planes, and basic slope stability calculations Plot mean vectors, cylindrical best fits, rose diagrams, and contour lines. View the plots from any orientation, not just looking straight down into the lower hemisphere Stamp each entry with time date and, if enabled by the user, location. See the location of a datum in the iOS Maps program Show realtime changes to the stereonet projection to help students understand the geometry of the device better Provide basic input and output of data using standard iOS conventions Work on both iPhones or iPads, both in portrait mode only. The program will work on iPods or iPads lacking a cellular data connection but those devices have fewer sensors and thus cannot be used in automatic data collection mode.

Provide manual data entry via either tapping and dragging on the stereonet or by typing values into text fields Groups of faults can be assigned different tags. You will probably want to do this based on location or other criteria. For example, you may want to have a tag labeled "Corral Quemado-Older" and anther "Corral Quemado-Younger". Carry out basic calculations such as: rotations about any axis, unfolding faults around local bedding, or measure angles between lines and between planes Plot P & T axes, (unweighted) moment tensor axes, P-T dihedra, fault plane solutions, and contour P & T axes.

It is a companion app to my Strat Desktop app. Some of the basic tasks that one can perform with the app include: Real time plotting of the stratigraphic section as it is being measured. Strat Mobile offers five (5!) ways of measuring a stratigraphic section: Using your known eye height while sighting down-dip through the device camera. Using your phone attached to a monopod and sighting down-dip through the camera — a modern digital Jacob staff Using a traditional Jacob staff. The device can determine the strike and dip of the bedding for you with the tap of a button Using a tape measure. You enter the tape azimuth, slope, start and end point, as well as the strike and dip of bedding, and the device will calculate the correct thickness automatically. Using your GPS position and strike and dip entered at the base and top of each measured interval Automatically record, latitude, longitude, time and date for every interval measured. You can define an unlimited number of lithology types (with corresponding colors and widths) to draw your section and tag your observations. Provide basic statistics on the section measured, including the thicknesses and percentages of each lithology See the locations of entire sections, measured intervals, and samples on a satellite image or road map.

The Chocorua Map app uses an exquisitely detailed shaded relief base map created with LiDAR elevation points spaced every one meter (3.3 ft). All of the publicly-accessible trails in the region are shown as tappable traces that not only reveal the trail name and length, but also shows the hiker how far they have come and how much further they have to go. The app also incorporates a full digital elevation model so the user can plot trail profiles and measure how steep different sections of each trail are, as well as determining the position an elevation of every tapped point. To the earth scientist, the topography reveals the glacial history of the region in astonishing detail and the app, written by a professional geologist, communicates that history to the users as tappable points of interest (POIs) which contain a written description as well as a photo or diagram of the feature. For the truly geeky, the user can even toggle on a bedrock geology overlay. POIs are also used to illustrate points of historical interest with some quoting from Frank Bolles' iconic books on the regional natural history. Finally, the user can add their own points of interest and photos as a kind of digital diary of their explorations in the region; user POIs also provide a means to send a user’s position to another user via text or email. The Chocorua Basin has notoriously poor cell phone coverage—a small price to pay for the preservation of a primeval landscape uninterrupted by cell phone towers—so the Chocorua Map app is completely self-contained with all of the information, topography, etc. that it needs to operate without any data connection necessary. Data are never downloaded from the internet and, unless the user explicitly chooses to send a text or email with their location to a specific recipient, all of their personal information remains completely private on their phone. The app is free to download for iOS devices and is not supported by any advertising; unfortunately, there is no Android version available at this time. https://www.rickallmendinger.net/gmde-lite daily 0.75 2025-03-12 https://images.squarespace-cdn.com/content/v1/5fd3a0dac47b7d485d6715e5/1619210928677-EHPETPL44YFYVFLR8WKQ/Simulator%2BScreen%2BShot%2B-%2BiPhone%2B8%2B-%2B2021-04-19%2Bat%2B17.50.26.jpg GMDE Lite - GMDE Lite GMDE Lite has been designed with small phone-sized screens in mind although it also works especially well on iPads (and even better with an Apple Pencil). The app borrows the best from both GMDE Mobile and Stereonet Mobile (and replaces GMDE Mobile completely) and presents that functionality in a clean, simple, map-centric interface. GMDE Lite is the perfect complement to GMDE Desktop. To see what GMDE Lite can do, click here to see the user’s manual. You can download a Demo dataset to try out in GMDE Lite before investing time and effort in learning how to produce the base materials (see below). Be sure to read the “READ ME FIRST” file. The user’s manual has detailed instructions for how to move data from your desktop to your iPhone or iPad.
