The individual event pages linked below describe our procedure to constrain the two-dimensional geometry of subduction interfaces at the locations of recent, moderate-to-large earthquakes that occurred on or near the subduction thrust. The 3D models provided in the "models" tab are built from a suite of similar 2D cross-sections made at regularly sampled intervals along the strike of each subduction zone.
