The Subduction zone initiation (SZI) Database is a cross-disciplinary and community-driven approach to gain an improved understanding of subduction zone initiation (SZI) and overcome the key long-standing questions of the Earth Sciences of how, when and where it happens on the Earth.

The interdisciplinary database features more than a dozen documented SZI events that occurred during the last hundred million years. The SZI Database and its related online platform,, is an easily-accessible, fully transparent, expandable platform that contains relevant SZI data and analyses, and establishes a common language to sharpen discussion across the Earth Science community.

Further details and the first novel scientific insights gained based on the database are presented in Crameri et al. (2020, Nature Communications).


The development of the SZI Database is supported by the Centre for Earth Evolution and Dynamics (CEED) via the Research Council of Norway and its Centers of Excellence funding scheme, Project Number 223272
