Electronic Supplement to
Rupture to the Trench: Dynamic Rupture Simulations of the 11 March 2011 Tohoku Earthquake

by Jeremy E. Kozdon and Eric M. Dunham

Particle Velocity Wavefield and Seafloor Deformation Movies

These movies show the horizontal and vertical particle velocity wavefields and seafloor deformation for our preferred dynamic rupture simulation of the Tohoku earthquake. They correspond to Figures 4 and 5 from the manuscript, which show snapshots from the same simulation. These movies demonstrate the effect of complex geometry and material structure on the rupture process. Development of a complex wavefield through interactions with the free surface and material layers are clearly evident. Extreme motion in the toe of the accretionary prism drives the rupture to the trench, resulting in a strong breakout phase and development of a dispersed wave train. Wave guide effects are also clearly evident as energy is trapped in the low velocity layers.


Movies*

Movie S1 [H.264-encoded MP4; 3.6 MB]. Horizontal particle velocity with a color scale is saturated at +/- 0.5 m/s. Only a fraction of the simulation domain is shown; there is no vertical exaggeration. A reference arrow showing the scale for seafloor deformation is given in the upper right corner. Red and blue arrows are for points landward and seaward of the trench, respectively.

Particle velocity wavefield for simulations with water layer

These movies show the horizontal and vertical particle velocity wavefields our preferred dynamic rupture simulation of the Tohoku earthquake with a water layer. They correspond to Figure 16 from the manuscript, which show snapshots and pressure plots from the same simulation.


Movies*

Movie S3 [H.264-encoded MP4; 8 MB]. Horizontal particle velocity with a color scale is saturated at +/- 0.5 m/s. Only a fraction of the simulation domain is shown; there is no vertical exaggeration.
