Gulfnet: Large-scale Nodal Seismic Deployment Along the Texas-Louisiana Coast
Description:
Offshore Gulf of Mexico (GOM) in Texas and Louisiana has been proposed as a major site for geological carbon storage. However, there are many active geological fault systems in the region, such as the Corsair, Clemente-Tomas and Frio Fault Zones. It is critical to study the dynamics of these faults and potential seismic events associated with any fault movement. Currently, there are few seismic stations near the coast to monitor these activities. To fill this observation gap, I have undertaken a massive field deployment effort. We have deployed more than 200 three-component nodes along the Gulf Coast, spanning from Brownsville, TX to Grand Chenier, LA (~800 km), within 80 km of the coastline. Acquired data show clear surface wave dispersion curves of ambient noise correlations, demonstrating high data quality. This 19-month observation effort aims to establish a risk baseline in both seismic structure and seismicity for the GOM northern offshore region. Results on the sensitivity of our network, and a baseline seismicity catalog will be presented.
