摘　　要：This paper proposes the mathematical model to investigate how to compute and analyze the tsunami wave parameters and the retrieval of its early warning using remote sensing technique to improve the detection rate.The different methods available for the evaluation of the tsunami detection systems are also introduced.This research work is to compute and analyze the tsunami wave parameters such as Eigen functions in deep,intermediate and shallow water regions.The computational and algorithmic analysis of tsunami wave parameters are achieved in three steps:the first step is to calculate the earthquake fault parameters such as length,width,area and displacement from the epicenter,which corresponds to the effect of its variation with respect to the earthquake magnitude.The variation of each fault parameters have been measured and recorded out over the certain moment of magnitudes(M).This shows smaller values as compared to the earthquake magnitude M 9.5 at which all the parameters shows very large response.The second step involves the measurements of water wave angular frequency in deep,intermediate and shallower region of ocean.The values of angular frequencies in deep water shows the lesser response as compared to other two water conditions because,in deep water the angular velocity of water particles travels with the lesser speed as compared to the shallower region as per Airy’s wave theory.The simulation results show the angular velocity in Deep Ocean is very less,moderate in the intermediate water and very high on the coastal region.It indicates the higher impact on coastal region.The third step involves the simulation study of measurement of tsunami Eigen functions such as orbital velocity,acceleration,wave potential in deep,intermediate and shallower water regions.The simulation result shows the resultant orbital velocity and accelerations in deep,intermediate and shallow water regions provides the similar response as angular velocity due to same proportion of the water displacement from deep to coastal region
