Poroelasticity and Fluid Flow Modeling for the 2012 Emilia-Romagna Earthquakes: Hints from GPS and InSAR Data

Figure 8

(a) InSAR (SBAS) time series measured at point 1 (orange dots) and at point 2 (dark green dots). The purple and the light blue circles represent the coseismic displacement of the May 20 and May 29 mainshocks, respectively, obtained by our model. The green and purple lines represent the modeled poroelastic deformation at point 1 and point 2, respectively (Figure 1). The blue line is the IC3 time dependence rescaled to represent the point 1 modeled poroelastic LOS displacement in the first 50 days following the May 20 mainshock (see inset). A 3D line of sight was considered for both the InSAR (SBAS) time series and modeled LOS displacement. (b) Modeled GPS displacement magnitude of station MO05 in S2 (black dashed line) and IC3 displacement magnitude for MO05 station over time (light blue line).
