My project title is "Reconstruction of Trench Logs as a Test for Interpreted Paleoseismic Events". The reconstruction of trench logs can be a valuable tool for testing the validity of an interpreted event horizon. By removing the deformation caused by an earthquake to its event horizon, one can see whether or not additional deformationis hidden in the trench sediments, indicating that more events may exist in the stratigraphy. This summer I will reconstruct trench logs from the Garlock fault, using Adobe Photoshop and Illustrator. I will retro-deform the logged statigraphy and demonstrate whether the deformation can be accounted using the event horizons that were identified in the field.

The trench site along the Garlock fault. In this photo the trench is hidden behind the mound of dirt excavated from the trench, which causes very dirty field work. |
This is a picture of the San Andreas fault and Garlock fault intersection. The field site approximately 150 km north east of the intersection. | ![]() |
