Figure 1. Figure 1. Spatial distribution of mainshocks with magnitude greater than or equal to 7.5 examined for dynamic triggering in Costa Rica. Each event is represented by its focal mechanism (also called a beachball diagram in reference to the average representation of the fault’s geometry). The events are also color coded by year of occurrence. Credit: Hajaji and Chaves, 2024, CC BY-NC-ND 4.0
