Take part in an experiment: Measuring tectonically offset features

Folks at Arizona State University and San Diego State University are conducting a study to test the repeatability, accuracy, and precision of lateral displacement measurements derived from high-resolution topographic Light Detection and Ranging (LiDAR) data. Please take a few minutes to participate! If you have any questions about the research or would like to use the materials as a classroom exercise, please feel free to email Barrett at jbsalisb@asu.edu.

This is what Barrett wants you to do:


I am a graduate student under the direction of Dr. Ramon Arrowsmith in the School of Earth and Space Exploration at Arizona State University.

For the next few weeks, we are conducting a research study with Dr. Rockwell at San Diego State University to test the repeatability, accuracy, and precision of lateral displacement measurements derived from high-resolution topographic Light Detection and Ranging (LiDAR) data.  The study is designed for users of all geologic backgrounds, so we cordially invite you, your colleagues, students, and friends to take a few minutes and help us validate our measurement methods.  All are welcome to participate, so please pass this message to anyone you think may be interested.  The deadline for submissions is March 16th.

Measuring tectonically offset geomorphic features using LiDAR

Your participation will involve a brief introduction to one of three measurement methods, measuring ten offset features, and completing a brief experience questionnaire.  You may choose to use more than one measurement method if you like.   Any contributions you can make are greatly appreciated.  The surveys, along with more background information, can be found at:


Your measurement estimates will aid in the development of methods used to assess the effects of earthquake ruptures.  All results will be kept confidential, and responses will be tied to an identifier rather than to a name.  The results of this study may be used in reports, presentations, or publications.

If you have any questions concerning the research study or are interested in using it as a classroom activity, please contact Barrett Salisbury via email at jbsalisb@asu.edu.

Cheers, and thank you for your time!
