Seismology Skill Building Workshop for Undergraduates

Advanced

The seismology skill building workshop is designed as an ~70 hour online course for undergraduates or recent graduates, regardless of major (e.g., computer science, geophysics, geology, math, physics) to build scientific computing and computational thiking skills while working with seismic data. The workshop materials below were used in 2020 and 2021 and the program will continue to run for at least summers 2022, 2023, and 2024. The goals of this workshop are to increase students'...  

  • interest in taking additional course work in seismology and scientific computing,
  • self-efficacy in using seismic data, and 
  • competitiveness in the graduate school or summer REU application process.

Timing: Summer. Every other week for 12 weeks, a module with ~6 assignments was released to students. On average students invest ~5-6 hours into the webinars and assignments.

Key Course Elements: A tailored Linux virtual machine, regular webinars (recorded for asynchrous use), a Slack workspace for peer-to-peer, and student-to-staff discussions), tutorial-style active e-learning assignments embedded in a learning managment system, and an optional final project. The workshop was delivered by two course faculty and supported by two seismology graduate student teaching assistants.

Course Content:

The course introduced seismological and computational concepts while also emphasizing how a seismologist might think about and approach the dataset or methodology at hand. Assignments were designed to build skills with Linux, GMT, SAC, webservices, seismic network processing, Python, ObsPy, and Jupyter notebooks. Additionally, research skills and topics likely to increase students' success were introduced including: how to read scientific literature, productive coding habits, seeking the mentoring you need, incorporating workshop learning into a resume or graduate school application, networking and developing elevator speeches.

Module 1 − Introduction to Linux command line, shell scripting, and basic plot generation with Generic Mapping Tools (GMT) that enables exploration of earthquake patterns in space, time, and magnitude, and Earth’s internal structure based on seismic wave travel times.

Module 2 − Introduction to Seismic Analysis Code (SAC) for viewing seismograms as both waveforms and spectrograms, and conducting time series analysis, filtering, and component rotation that enables detection, characterization, and interpretation of seismic wave patterns.

  • SAC Tutorial 1: Introduction and Reading/Writing Data Files
  • SAC Tutorial 2: Obtaining Seismic Data
  • SAC Tutorial 3: Fourier Analysis and Filtering
  • SAC Tutorial 4: Body Waves
  • SAC Tutorial 5: Earthquake Source Directivity
  • SAC Tutorial 6: Convolution and Cross-Correlation

Module 3 − Use the myriad of IRIS waveform, metadata, and earthquake catalog request tools (e.g.., web services, earthquake browser, Wilbur, MUSTANG, etc.) to check data availability and access data that enables exploration of relationships between earthquakes and plate boundaries and earthquake frequency and magnitude.

Module 4 − Use various methods to visualize collections of seismic waveforms for a given earthquake and software for forward modeling and inversion that enables both estimation of subsurface velocity structures and earthquake hypocenter and fault plane solutions.

Module 5 − Introduction to Python and commonly used libraries (e.g., NumPy, Matplotlib, Pandas, and ObsPy) for retrieving, processing, and plotting of data tables and times series that enables rapid scientific analysis of earthquake catalogs and seismic waveforms.

Module 6 − Use existing and create new Jupyter Notebooks with Python to explain and share code with other scientists that enables advanced seismogram processing including removing an instrument response, calculating a spectrogram, and estimating temporal changes in cultural noise.

Final Assignment (Optional) -The final assignment for the Skill Building Workshop is to develop a Jupyter Notebook*  showcasing what students have learned from this course!
