Advancing Chilean Subduction Zone Science Together


June 12-14, 2023 | Termas El Corazón, Chile 

AndesNet & SZ4D Scientific Community Workshop

Meeting Goals

To develop a consensus recommendation from AndesNet to SZ4D regarding the geographic region of SZ4D instrumentation in Chile, and to develop a plan for priority AndesNet activities (e.g., analysis of instrumental data, geological work, modeling) under the SZ4D Implementation Plan. At the end of the meeting, we aim to finalize a proposal about the zones of interest of Chile, based on inputs and discussions during the meeting.

SZ4D (Subduction Zones in Four Dimensions) is a rapidly developing initiative for a long-term, interdisciplinary, community-driven research program to define the limits and possibilities of predicting geohazards.

AndesNet is the new coordination network of Chilean subduction zone scientists. This network has been created to serve as a coordination platform for investigators actively working on the understanding of hazard-related natural processes that occur in association to the dynamics of the Chilean subduction zone. AndesNet is the natural counterpart of SZ4D in the development of initiatives oriented to consolidate the scientific collaboration between US, Chilean and Argentinean communities and further geophysical instrumentation of the local subduction zone in the near future.

The Chilean subduction zone has been identified as the possible site of a decade-long research effort that would involve comprehensive suites of new offshore and onshore instrumental measurements to study processes underlying geohazardous phenomena in both space and time.


We announce an NSF-supported 3-day workshop (June 12- 14, 2023) at Hotel Termas El Corazón (close to Santiago) and invite the Chilean and Argentine geoscience community to participate in this event. The main goal of the workshop is to identify optimal sites and sensing technologies for deployment along Chile, inland and offshore. The meeting will be preceded by an Early-Career Investigator symposium on Monday June 12 (more information will become available soon).

​The workshop will include 17 scientists from the USA (representing the SZ4D Initiative) and ~60-70 Chilean and Argentine participants, 20% of whom will be early-career scientists (PhD students and postdoctoral researchers). Scientists who are applying for an invitation must be from Chile or Argentina. Transportation, lodging and meals for all invited participants will be covered by the SZ4D Initiative. The workshop agenda will include presentations and guided conversations. In order to facilitate the discussion, this will be a hybrid English/Spanish meeting.

​If you are interested in participating in this workshop, please read the executive summary of the Implementation Plan and complete the application form no later than May 5th. Based on the information collected from each applicant, the Steering Committee of SZ4D (with the advice of the local organizing committee) will select the workshop participants and communicate invitations by May 15th. Those who have finished their survey by May 5 will be given highest priority to attend the meeting.

​We hope to see you soon in Termas El Corazón!

Early Career Symposium Agenda

Meeting package

Early Career Symposium

The meeting will be preceded by an Early-Career Investigator symposium on the Monday morning. Lodging on Sunday night will be available for participants attending the symposium. More information will be available soon

Post-meeting Field Trip

Led by Luisa Pinto Lincoñir, visit at least three outcrops of the Cariño Botado fault system outcrops. These outcrops include dated alluvial tilted and non-tilted deposits that delimit the age of the last activity of the main fault of the system. In addition, we can see in the distance fluvial and alluvial deposits raised tens of meters above the current rivers/creeks that show an older activity of the faults. To understand the implications of the seismic hazard of these faults, they will be contextualized in a geological map and satellite image, in addition to a field guide.

The mini-bus will depart from Termas Resort after the meeting ends at 15:30.
