We've never been inside the fault zone before. The goal has been to understand the basic mechanics of faults.
We have greatly reduced the number of people we have doing research, we have had to cut way back on field investigation programs, we've had to work smarter with less.
We've looked at fossil earthquakes, we've made computer models, and we've made earthquakes in the laboratory. We've studied them from afar, but we've never before been where the action is.
