I often have a hard time explaining to friends and family what exactly INTViewer does. The moment I use the word “seismic,” the listener’s mind automatically shifts to the topics of seismic activity and earthquakes, and I need to explain oil & gas exploration technologies before I even get to the software. By then, I have lost my audience. Today, I’ll try a different technique: I’ll describe the capabilities of INTViewer that actually cater to earthquake mapping. I will show how you can use the built-in capabilities of INTViewer to map recent earthquake activities.
