Extended Data Fig. 3: Corona growth with time, and Coulomb stress imparted to focal mechanisms in the core and corona.

a–b, Two-day and two-month corona extent. c, Simplified core area with beachballs colored by maximum Coulomb stress change. Because for each mechanism, we take the nodal plane with the most positive (maximum) stress change, these results could be biased toward stress increases. Mechanisms from 1998/01/01 - 2011/03/10, M ≥ 3, depth≤150 km, from F-Net catalog.
