Toward Data Lakes for Recorded and Simulated Earthquake Ground Motions
Date: Monday, 2 September 2024 (13:00 CEST) until Wednesday, 4 September 2024 (12:00 CEST)
Location: GFZ Potsdam, Germany (hybrid)
Description:
This workshop seeks to foster collaboration and discussions on the exploration and definition of a standardized format for both real earthquake motion data and numerical modeled synthetics, collect and give access to the available/ready-prepared data and synthetics from research groups around the world, explore data lake platform options, identify target user groups and examine potential engineering uses of such data lakes.
The initiative builds upon the discussions and meetings organized by the Consortium of Organizations for Strong Motion Observation Systems (COSMOS) in the past two years (https://pubs.usgs.gov/publication/70248701).
Target Audience:
This workshop aimed at experienced scientists working in fields such as physics-based numerical modeling, seismology, and earthquake engineering, as well as related fields like insurance and data lakes. It was designed for both users and creators of data lakes.
The meeting was conducted via Zoom for online participants, and recordings will be made available online within the upcoming weeks.
