LaDiCaOZ and Lateback: reconstructing horizontal offsets in topography websites for tools

Dr. Olaf Zielke developed some very useful tools for interacting with high resolution topography for horizontal back slip of offsets due to earthquakes. These were the tools for the science results presented in:

  • Zielke, O., Arrowsmith, J R., Grant Ludwig, L., Akciz, S. O., High resolution topography-derived offsets along the 1857 Fort Tejon earthquake rupture trace, San Andreas Fault, Bulletin of the Seismological Society of America, doi: 10.17850120110230, vol. 102 no. 3 1135-1154, 2012.
  • Zielke, O., Arrowsmith, J R., Grant Ludwig, L., Akciz, S. O., Slip in the 1857 and earlier large earthquakes along the Carrizo Plain, San Andreas Fault, Science, DOI: 10.1126/science.1182781, p. 1119–1122, 2010.
He also documented the approach and the software in this paper:

Olaf is now at KAUST. His email address is:

He has made the supplemental on line material from the Geosphere paper available here.
And, the LaDiCaoz_LiDARimager tools and information is available on this dropbox link
