Well I think I'm rapidly approaching the end of the window I had to work with this and figure out how to add it to osm, if anyone else wants to try, go for it. In the meantime, I just figured out how to turn it into a kml, it contains sites in addition to those mapped by British Geological Survey, Durham University, ICIMOD, NASA-JPL, Univ. of Arizona -- though one coincides: theirs: 20150508_hazard_db:FID 120 this eq_kml_shp:id -80 and eq_kml_shp:id -81. Their db is available at: https://data.hdx.rwlabs.org/dataset/lands
This kmz here (rougher than I'd like but it will have to do... ) All the best, John On Mon, May 11, 2015 at 8:59 AM, john o'l <ol.john...@gmail.com> wrote: > Also linking a website with links to a report on the Oso landslide as it > is somewhat familiar to me > http://www.geerassociation.org/GEER_Post%20EQ%20Reports/Oso_WA_2014/index.html > For our purposes, some of the key points made are: the initial phase of > the slide (most destructive/fastest and most distant runout) -- was an old > slide that had remobilized. 200 vertical meters of material which covered a > horizontal distance of 1000 meters.
