Earthquake Location part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Earthquake location is an interesting and significant aspect of seismology. 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.
Field Geophysics â Sampling and Aliasing Theory and Examples part of Cutting Edge:Geoscience in the Field:Activities
Collecting geosciences data in the field involves sampling in time and space. Sampling includes theoretical limitation and the possibility of aliasing which has severe effects on sampled data. The concepts are applicable to spatial sampling and geological data. The discussion is most appropriate for classroom or computer laboratory use prior to field data collection.
SAGE student evaluation form part of Cutting Edge:Geoscience in the Field:Assessment Tools
SAGE Student Evaluation Form - completed by students at the end of SAGE summer program.
Computer-Aided Analysis For Geosciences part of Cutting Edge:Course Design:Goals Database
Applications of statistical, numerical and mathematical methods useful for Geosciences; Matlab programming.
Vibroseis Correlation - An Example of Digital Signal Processing part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
In the vibroseis method of seismic exploration, the seismic energy source (ground vibration controlled by shaking the mass of the vibroseis truck) is distributed over a time of several seconds. To see how vibroseis recording and processing works, we will look at the mathematics of vibroseis signal processing in both the time and frequency domains and view illustrations of the recorded and processed signals.
