G&T Seminar
G&T Seminar
Welcome to the G&T seminar website. This international virtual seminar started as a way to replace many of the department seminars which were disrupted or canceled due to COVID-19. The virtual format allows us to learn about research from around the world from wherever we might be.
The seminars will take place on Zoom at 11:00am Eastern time (UTC -4) every Wednesday.
Each seminar will be 40 minutes** followed by 20 minutes for questions.
** Note longer discussion time
If you would like to join in the seminar, please sign up at the link below to join our mailing list and receive the emails to access to the Zoom meetings.

Complexity and Simplicity of Injection-induced earthquakes in the Raton Basin
Waste-water injection induced seismicity has been active in the Raton Basin for the past two decades, including several M>4.0 normal-faulting earthquakes. To characterize the injection-induced fault reactivation processes, we utilize the state-of-art techniques to automatically detect and locate the seismicity using two datasets: 1) 8 broadband stations available since 2016 with an averaged spacing of ~30 km and 2) 96 high-frequency nodal instruments that were deployed for one month in the southern section of the basin in the summer of 2018. The two catalogs with ~30,000 and ~10,000 earthquakes show consistent patterns: clustering into multiple fault systems ranging from N-S, NE-SW normal to oblique dip-slip regimes. Further focal mechanisms and finite fault analysis suggest high fault and stress heterogeneity in this injection setting. On the other hand, statistical behaviors of the clusters are generally comparable to tectonic sequences. The detailed fault structures and earthquake cycle statistics offer an observational base for future mechanical modeling and hazard mitigation.
Seminar Rules
Seminar Rules
Modeled after IPAM’s advice on running virtual seminars:
All participants will be muted upon entry
If you would like to ask a question, please virtually raise your hand and/or message in the chat, and then unmute yourself to pose the question and mute yourself again.
Please use a Zoom user name which matches your real name
Please keep your sound muted during the seminar.
The seminar will remain active until 12:30pm Eastern time. After the talk and questions, participants are welcome to stay and chat with colleagues.

On June 10th, academics were called to action to #shutdownSTEM and #shutdownacademia for #strike4blacklives. The G&T Seminar was postponed to honor the call to strike and instead we held a discussion where people shared resources and concerns and discussed ways forward. As a result of that discussion, we have been compiling some resources for the Geophysics and Tectonics community. Please check out our Resources page with links to other sites, ideas for getting started and our own resource list we started during the call.
