About the workshop

Chile lies on one of the world's most active tectonic boundaries yet access to distributed acoustic sensing (DAS) expertise and infrastructure remains extremely limited in the country. This workshop aims to help close that gap.

Over three days, participants will move from the fundamentals of fiber-optic sensing and work up to a real field deployment on the UdeC campus, followed by full data-analysis pipelines using modern open-source tools and machine learning.

The workshop is designed to democratize knowledge: is free to attend, travel scholarships are available, and we especially encourage applications from underrepresented groups, women, and early-career scientists (ECS).

Funding for the Training on Distributed Acoustic Sensing for Earthquake Research and Seismic Building Response was made possible by the Seismological Society of America through their SSA Community Grants Program.

Three days, one complete pipeline

From seismic theory to fiber deployment to earthquake products — participants leave with practical skills and a working toolkit.

Sep

Day 1 — Scientific overview & seminars

📍 Auditorio Alamiro Rebolledo · CFM UdeC

Invited talks covering DAS theory, fiber sensing fundamentals, and international case studies. National and international speakers will present applications in earthquake analysis, seismic imaging, seismic hazard, structural monitoring, physics, telecommunications, among others. Space reserved for lightning talks by students and ECS.

DAS theory Applications Invited talks Student & ECS lightning talks

Day 2 — Instrumentation & field deployment

📍 Outdoor fiber-optic network · UdeC campus

Hands-on experience with the DAS instrument. Participants learn deployment best practices, safety protocols, and logistical considerations, then deploy the fiber-optic cable on campus. Real seismic signals are recorded during the session, and this data may be used in Day 3.

Day 3 — Data processing & interpretation

📍 Computer Lab (TBD) · FI UdeC

Full workshop day: "Introduction to DAS for Seismology." Participants work with DAS data formats, preprocessing pipelines, and open-source tools, along with machine learning approaches for phase picking. The day includes group exercises, a plenary discussion on future research directions in Chile.
