Fostering international collaboration and communication between active science networks studying subduction zone geohazards.

The study of subduction zones requires comparison across regions to allow for insights about the controlling factors of the tectonic, volcanic and landscape systems. 


SZNet - the international component of SZ4D - is a coordination network for an international community studying subduction zone geohazards. SZNet has been created to connect existing regional networks and provide a unified framework when studying these hazards. SZNet is currently composed of 15 networks across 5 continents with a particular emphasis on improving observations in Chile, which hosts one of the world’s most geologically active and accessible subduction zones. As such, SZNet has three main missions:

  1. to compare observations of subduction zones around the globe with a common dataset and understanding,

  2. to cooperate to consistently instrument critical subduction zones that can provide key and transferrable insights, and

  3. to develop and nurture an international and diverse cadre of early career scientists that is equipped to make the necessary breakthroughs. 


In pursuit of these missions SZNet will host a variety of activities including workshops, webinars, data exchanges, field schools, pilot projects and student exchanges. Planned activities and milestones are summarized in the table below, and are organized around SZNet's 3 main missions.


 SZNet is supported by funding from the National Science Foundation AccelNet program under award 2301732.
