SZ4D Open DAS Data for Subduction Zone Environments

SZ4D Open DAS Data for Subduction Zone Environments#

https://www.sz4d.org/events/agu-mini-workshop-das-subduction-zones

Overview#

This half-day mini-workshop aims to introduce participants to publicly available DAS datasets and open-source tools, demonstrate analysis techniques relevant to subduction zone science, foster collaboration and data sharing to enhance reproducibility within the SZ4D community, and build connections among early-career and established researchers.

The event will take place at the Tulane River & Coastal Center (1370 Port of New Orleans Pl, New Orleans, LA 70130), located one block south of the Convention Center (map)

Get Started#

We will use the EarthScope GeoLab computing environment for this workshop. If you do not have access to GeoLab, please sign up at https://www.earthscope.org/data/geolab/.

When launching a GeoLab Jupyter hub, please select the “GeoLab” environment. Please use an allocation with more than 7 GB RAM. After launching the jupyter hub, copy and run the scripts below in a terminal.

wget https://raw.githubusercontent.com/uwfiberlab/sz4d_das_workshop/refs/heads/main/configure.sh -O configure.sh
chmod +x configure.sh
./configure.sh

Wait until the configuration script finishes, then navigate into sz4d_das_workshop -> notebooks, and select the session notebook. When running the notebook, select the workshop kernel.
