Analysis of the Crust Deformations before and after the 2008 Wenchuan Ms8.0 Earthquake Based on GPS Measurements
Figure 3
Principal strain rates distribution before Wenchuan earthquake. Double arrows show the principal strain rate labeled at the center of individual triangles. Red circles represent the main- and aftershocks with magnitude greater than 6.0. The Delaunay triangle network is formulated with GPS points as their vertexes. The red lines show the active faults based on [2]. (Only the principal strain rates passed the drawn in (a).)
