Surface Deformation

DLR has prepared maps of horizontal surface displacement.

CEA has prepared maps of surface displacement components.

Anthony Sladen, Caltech has prepared a source model based on waveform inversion and used it to predict surface displacement:


Andy Freed of Purdue University has created a postseismic relaxation model:

Cumulative predicted postseismic displacements between 3 weeks and 1 year from the time of rupture based on finite element model calculations . These displacements are predicted to increase dramatically in subsequent years, though the pattern should remain fairly constant. (a) Map showing model displacements at current GPS locations (thick arrows) based on two rheological assumptions, one where postseismic relaxation is dominated by flow in the deeper mantle (red arrows in (a), red curve in b), and one where relaxation is dominated by flow in the lower crust (blue arrows (a), blue curve in (b)). The green arrows in (a) show the full pattern of predicted deformation associated with the mantle flow model. (c) and (d) show calculated vertical displacements of this time period (red: uplift, blue: subsidence) for the mantle and lower crustal flow models, respectively. (e) Shows the difference in vertical displacement between the two models

Coulomb Failure Stress

Eric Calais of Purdue University has made a preliminary estimate of the coseismic failure stress field:



USGS-WHOI-DPRI stress triggering model:
Jian Lin (WHOI), Ross Stein and Volkan Sevilgen (USGS) and Shinji Toda (DPRI) have resolved coseismic Coulomb stresses on neighboring faults to determine which are most likely to produce triggered earthquakes. Their figure (above) shows changes in seismic hazard. Their report includes a short explanation of the technique and assumptions. The USGS has also issued a statement about the hazard implications.

Digital faults (matlab format) contributed by Volkan Sevilgen and Ross Stein of the USGS.
