This webinar presents tools available in O-Help for GIS personnel, engineers, planners, and others who need information related to seismic hazards.  This webinar will provide an introduction of the O-HelpwebGIS platform, the hazard layers and CSZ scenario events available, how to use the data in O-Help as well as within GIS software, and additional analysis tools available.  We perform a live demonstration of O-Help and leave time for questions.  This webinar also discusses current efforts underway to expand the capabilities of O-Help to serve as a decision support system. O-Help can be accessed at http://ohelp.oregonstate.edu.
