University of Calgary Free Software for Seismic Researchers

The University of Calgary Seismic Research Team (CREWS) has developed a comprehensive suite of free software tools specifically designed to provide efficient solutions for seismologists and researchers worldwide. These tools cover multiple core research areas including seismic data analysis, waveform processing, and focal mechanism solutions.

The CREWS free software suite is characterized by its open-source nature and cross-platform compatibility, allowing researchers to freely download, modify, and extend its functionality. Several tools feature optimized algorithms specifically designed for seismic waveform visualization and processing, employing techniques such as digital signal processing (DSP) methods for noise reduction and advanced filtering approaches. These are particularly suitable for applications in seismic monitoring, hypocenter localization using triangulation methods, and crustal structure investigations through seismic tomography algorithms. The software additionally supports multiple seismic data formats (including SAC, SEED, and MiniSEED) through built-in parsers and conversion utilities, ensuring compatibility with data from various research institutions.

Beyond academic research applications, these tools are also valuable for seismic hazard assessment using probabilistic seismic hazard analysis (PSHA) methodologies and emergency response scenarios. By providing these resources, the University of Calgary promotes open collaboration in earthquake science, reduces research barriers through accessible computational tools, and advances the development of global seismology.
