What This Document Is
This is a lab assignment for GEOL 1121K, Introductory Geology I at Georgia State University. It focuses on earthquake geology and seismology, specifically the methods used to locate earthquake epicenters. The assignment, titled “Earthquakes Lab,” is designed for individual student completion.
Why This Document Matters
This lab is a core component of the course, providing hands-on experience with interpreting seismic data. It’s intended for students needing to apply theoretical knowledge of earthquake wave behavior to real-world scenarios. Successful completion requires analyzing travel-time curves, using a nomograph, interpreting seismographs, and ultimately, creating a triangulation map to pinpoint earthquake locations.
Common Limitations or Challenges
This document outlines the assignment requirements and provides a basic introduction to the concepts. It does *not* provide detailed instruction on how to use Google Maps for mapping or a comprehensive explanation of seismograph interpretation. Students will need to rely on course lectures, the provided “Lab Guide packet,” and their own research to fully complete the assignment.
What This Document Provides
The document includes:
* An outline of the three parts of the lab: Time-Travel Curves, Nomograph/Seismograph/Time-Distance chart work, and Earthquake Triangulation.
* A list of deliverables: a PowerPoint document and a triangulation map.
* Sample questions related to interpreting travel-time curves (P-wave and S-wave arrival times).
* Contextual information regarding the impact of earthquakes and the surprising relationship between tectonic activity and human settlement.
