Assignment due Weds, 10/31/2007 on your web page: Produce the following maps of the Wallace Creek area: Hillshade Nicely colored DEM semi transparent over the hillshade 1 m and 2 m contour interval maps over the hillshade Topographic profiles across the scarp southeast of Wallace Creek and along Wallace Creek. Follow the tutorial and export them as Excel files. Plot them neatly in Excel. Note that these are the two profiles you produced by hand back in an early exercise). Using the measurement tool, measure the offset of the main channel and the beheaded one (the big curving one to the NW). How far are they offset? If radiocarbon dating indicates that the main Wallace Creek channel formed (and was straight and perpendicular to the fault) at 3700 years ago, what is the average slip rate (offset divede by age)? Using the measurement tool, determine the amount of offset indicated by the little offsets to the southeast of Wallace Creek. How far are they offset? We assume that those formed in the last great earthquake. If you know the slip rate (just calculated), and we assume that the fault will be ready to fail again once the slip accumulates up to what was released before, how much time might we expect between earthquakes (divide the offset by the slip rate to get a time). If the last earthquake was 1857, are we due for an earthquake (hazard assessment is much more tricky than this, but it is quick estimate).
