Fig. 2. Seven global pinch points.
Map of regions or pinch points where clustering of critical systems and infrastructures converge with regions of lower-magnitude volcanic activity (volcanic explosivity index 3–6). These pinch points are presented with the likely associated volcanic hazard activities in circles; where yellow is tephra/ash fallout, brown is submarine landslides, blue are tsunamis, and green are lahars. Each pinch point also includes the potentially impacted systems, including aerial (A), maritime (M), trade and transportation networks (TT), and submarine cables (SMC).
