AndesNet & SZ4D Scientific Community Workshop

The second edition of the AndesNet & SZ4D Scientific Community Workshop took place in Los Andes, Chile, on June 12-14, 2022. The meeting was preceded by an Early Career Symposium. The participant list and the meeting agenda as well as the collection of keynote lectures and lightning talks are available below.

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.
