Understanding tsunamis and developing an early warning system (EWS) is of great practical interest owing to considerable damage they inflict on human life and material. The tsunami life-cycle encompasses its generation via rise of the ocean floor, propagation over deep oceans and inundation on land masses. Part of my current work involves inverse problems towards characterizing the tsunami source using the varied and widely available data streams e.g. tide gauge records, global positioning data, satellite altimetry etc. This is in order to simulate a range of possible outcomes with different risk levels that shall inform the EWS. Since a rapid computer simulation of the above processes is essential for a realistic EWS, parallel computation and development of fast model emulators is necessitated. The large, noisy and varied datasets require tackling a host of issues regarding but not limited to ascertaining the value of information contained in the data, prioritizing data from different sources and use of statistical techniques.
