A Public Server for the Tsunami Modeling

Recently MOST (Method of Splitting Tsunami) software package has been accepted by the USA National Ocean and Atmosphere Administration as the basic tool to calculate tsunami wave propagation and evaluation of inundation parameters [Titov1998]. Modern computational technologies are making possible to calculate rather well tsunami wave propagation over the deep ocean provided that initial displacement in known [Lavrentiev2008]. The key point of these investigations is the concept of “multi method” technique for better determination of the initial displacement parameters by the recorded time series processing combining with real time signal processing and technique of “calculations in advance”.  The system database of these scenarios includes of many pre-calculated data of possible tsunami behaviors according the epicenter coordinates, coast shape, features of media, etc.

A public server client/server architecture and infrastructure will be developed including input/output parameters of numerical tasks for remote computational facilities as well as structure of tsunami data to be stored and assembled. The users can grant a free computer time for calculations of scenarios or obtain results of possible tsunami behaviors.
