Subduction initiation forcing
The illustration depicts two endmember states in subduction zone initiation: vertically-forced and horizontally-forced subduction initiation.
Subduction initiation is explained in this collection of accurate, accessible science graphics, designed to make understanding this key geological process clear and engaging. These visuals explore how and where subduction zones first form, triggering the descent of one tectonic plate beneath another and setting the stage for earthquakes, volcanic arcs, and mountain building. Perfect for educators, students, and geology enthusiasts, this subduction initiation graphic collection turns complex geodynamic concepts into visually rich, easy-to-grasp resources for teaching and learning.
