Effect of tsunamis from Makran Subduction Zone and its impact on the Androth Island of Lakshadweep

The 27th November 1945 tsunami generated due to an earthquake of magnitude of 8.1 (\(M_{w}\)) in the Makran Subduction Zone (MSZ) is one of the most devastating tsunami in the Arabian sea. One of the prominent feature in the Arabian sea about 1700 km from the MSZ is the Lakshadweep Islands. Tsunamis generated in the MSZ would travel into the Arabian sea and would cause damage along the west coast of India and Lakshadweep Islands. In this paper Mathematical Simulation of the tsunami generation from this zone, its propagation into the Arabian sea and its impact on the Androth Island of Lakshadweep is studied using a Mathematical Model. The possible arrival time and the wave heights around different locations of the selected island have been quantified. Three different scenarios by changing fault parameters and manning coefficients are computed and the differences in the arrival time and tsunami wave amplitude in each case is observed. Results obtained is discussed and compared with the available tabulated information in literature.
