What's New in Science, Dave Moecher - Fault Behavior and Complexities

What's New in Science University of Kentucky Dave Moecher

Part 2 of 4: Fault Behavior and Complexities This section discusses the approaches for understanding faulting and generation of earthquakes. Understanding faulting and earthquake generation is basic first semester physics, in particular understanding forces and friction, elastic behavior of crust and propagation of waves through matter. Understanding earthquakes also requires geologic examination of ancient faults and fault rocks that are now exposed at Earth’s surface.

What's New in Science, Dave Moecher - Basics or Prediction and Risk Assessment

What's New in Science University of Kentucky Dave Moecher

Part 3 of 4: Basics or Prediction and Risk Assessment Past earthquake prediction efforts were based on several basic tenets (“the earthquake paradigm”) that are now being questioned by some seismologists. Earthquakes exhibit simple statistical distributions that can be used to understand their recurrence. Basic probability can be used to estimate earthquake recurrence intervals. Seismic risk is defined.
