AB: FACTS (Facility for the Analysis and Comparison of Tsunami Simulations) is a system developed by NOAA's Pacific Marine Environmental Laboratory. The system uses a web interface to archive and access the results of numerical tsunami simulations. The system uses the tsunami propagation and runup model MOST to perform inundation computations. Recently, a standalone node of the FACTS system was brought online at the University of Southern California (http://usc-facts.usc.edu). The purpose of this node is to compile all of the modeling runs completed to date for the purposes of tsunami inundation and evacuation mapping for the California Office of Emergency Services, as part of the U.S. National Tsunami Hazard Mitigation Program. One highlight of the system is the ability for the end user to specify a specific location for detailed analysis and data output. Time series information can be obtained for arbitrary points within the flow field. The results can be inspected in plots generated in real time by the system or the data can be output in text format for later use By archiving a database of numerical simulation results, a probabilistic analysis of tsunami hazards is beginning to take shape. Currently, the original FACTS node (http://ferret.pmel.noaa.gov/FACTS) gives the user the ability to create a `designer tsunami' from sources along the various circumpacific subduction zones. By discretizing the subduction zones into `unit' sources that can be switched on or off and combined, unique tsunami sources can be created and the results analyzed. Hopefully, this node will be the first of many in an expanding network linking tsunami researchers and modelers around the world. Future plans include nodes for the East Coast, Caribbean, New Zealand, Australia, and Turkey.
