Extended Data Fig. 8: Effects of Strain Cell Size on Surface Strain Characteristics.
From: Localized fault-zone dilatancy and surface inelasticity of the 2019 Ridgecrest earthquakes
Illustration of how strain inversion cell size impacts strain fields from the 2019 Ridgecrest earthquakes. The top row shows the resulting shear strain field when inverted using triangulation (a), and 4x4m (b), 10x10m (c), and 30x30m (d) averaging cells respectively. e) Strains within the black profile box. Regions in the anelasticity zone exceed the expected failure strain (0.5% strain), while regions in the elasticity zone do not fail. Changes in the strain cell resolution serve to create a smoother strain field with smaller peak strain values, but they also do not significantly impact the interpreted permanent strain zone width. The values in the profile are plotted as the absolute value of the shear strain, in logarithmic space.
