Description of the activity/assignment
Earthquake location is an interesting and significant aspect of seismology. Locating earthquakes is necessary for compiling useful seismicity information, calculating magnitudes, and study of fault zones, Earth structure and the earthquake process. Methods of earthquake location involve understanding of seismic waves, wave propagation, interpretation of seismograms, Earth velocity structure, triangulation, and the concepts (and mathematics) of inverse problems. Because earthquake location can be approached with relatively simple to very complex methods, it can be included in various levels of educational curricula and for "in-depth" study. Progressively developing a deep understanding of concepts, computational techniques and applications (and the capabilities, limitations and uncertainties of these applications) is a characteristic of science and an opportunity to "learn science by doing science." A number of methods that vary from simple to complex are available for learning about earthquake location. The methods also allow connections to other important concepts in seismology and provide a variety of approaches that address different learning styles and can be used for reinforcement and assessment.
