Tweb is a web-based tsunami modeling research tool that was developed to provide distributed and remote access to the modeling and forecasting infrastructure developed for operational use at NOAA’s Center for Tsunami Research (NCTR). ComMIT is a desktop application providing a powerful and fully functional, yet easy-to use graphical user interface to the NCTR-developed MOST tsunami forecasting model. ComMIT is a self-contained downloadable application available from NCTR for use by qualified and novice modelers alike. We have recently added functionality that allows ComMIT to retrieve the prefered model solution for tsunami events from the Tweb Web Service. A ComMIT user with access to high resolution coastal bathymetry can generate detailed inundation models for real or synthetic events for their areas of interest. Then with the push of a button, the ComMIT user can upload their model results to Tweb where a community of tsunami modelers and forecasters can see these model results displayed in Tweb, along with other operational and contributed inundation forecast models. Besides the crowdsourcing aspect of tsunami modeling that will allow tsunami forecasters to get inundation model inputs from areas they normally would not consider, these contributed flooding models could provide forecasters with an early model solution verification capability by allowing model result comparisons with local tide gauge data in areas where operational models have not been developed. In addition, with the proper training this tool is very useful for education and as a vehicle for community tsunami hazard assessment. We will illustrate the model solution and results interchange capabilities now possible with these two applications.
