Workshop Overview

A diagram of the Earth and seismic waves Details

Seismic waves provide powerful ways to probe the deep, hidden earth that allows interpretation of the architecture of Earth and processes past and present that have shaped the planet. Seismometers are our ears to Earth's activities, and they are used to monitor not only earthquakes but also a wide ranch of natural and man-made sources that include volcanoes, glaciers, landslides, storms, explosions, animal migrations, and urban noise. Visualizations of seismic waves, as represented by a variety of graphics, animations, simulations and Java Aplets, provide windows that lead to deeper understanding by learners at all levels. The purpose of this workshop is to draw together geoscientists who regularly use seismic waves in their teaching and research to build a comprehensive collection of visualizations and instructional activities that demonstrate how seismic waves can be used to interrogate and investigate the sounds of the Earth. Topics that will be addressed include: visualization of seismic waves as they propogate through Earth; working with seismograms to determine their characteristics such as arrival phases, amplitudes, and frequencies; working with seismogram data and related software packages such as QuakeCatcher, SeisMac, and APPS for the I-Phone.

Presenters include:

The format of the virtual part of the workshop will include a series of whole-group presentations and demonstrations using the Elluminate teleconferencing software, and we will also provide listservs and closed, web-based workspaces to help individuals and small groups to work on the development and review of instructional activities.

For each visualization in the collection, we would like to provide the contexts such as fundamental principles, worked examples, annotations, and tutorials as appropriate to help our non-expert users (other faculty and students) to be able to understand how seismic waves are used to investigate a variety of Earth topics.

Animations of the propagation of seismic waves across the 400+ stations of the Transportable Array of EarthScope are available for many major earthquakes at http://eqseis.geosc.psu.edu/~cammon/QA/. Details
Workshop Goals

The goals of this workshop are to:

Example of a set of teleseismic seismograms showing the major phases recorded. The three components of the seismograms can be represented as either vertical, north, and east, or as vertical, radial, and transverse. Details

Who Should Attend?

Dates

Virtual Workshop

The virtual workshop will be convened on Wednesdays (Feb 2, 9, 16, 23; March 30, April 6) for ~2 hours starting at noon Central Time Zone. These on-line sessions will include presentations and demonstrations from a series of invited speakers (TBA), and there will also be time set for on-line interactive sessions with the workshop participants to share ideas and approaches and to review and design teaching activities around selected seismic wave visualization methods.


Face-to-Face Workshop

The face-to-face half-day workshop will be held on the afternoon of Sunday, December 4, at the Fall AGU meeting in San Francisco. This will give participants an opportunity to meet in-person and discuss their experiences from the Fall semester, when they will have had a chance try out some of the ideas proposed during the online workshop.

The different frequency contents of seismic body and surface waves can be demonstrated by windowing the different portions of the seismogram and transforming them into the frequency domain. Details


Expectations

Participants are expected to:

Costs

Registration for the workshop is $50. This will secure your place in the workshop and help offset costs of using the teleconferencing software. Pay your registration fee
