LEGEND Scale 1 : 50,000 TSUNAMI HAZARD MAP - SHEET 03 Main Road EEE Province Boundary LIMITATIONS 20 10 0 20 40 60 80 100 MAP INFORMATION As the nature of the tsunami depends on the initial seabed deformation due to the earthquake, which is poorly understood, the Minor Road EEEE District Boundary METHOD OF PREPARATION largest source of uncertainty is the input earthquake. Another significant limitation is that the resolution of the modeling is no Other Roads D.S.Div. Boundary Kilometre greater or more accurate than the bathymetric and topographic data used. The resolution of the model also constrains its µ Railway Tsunami inundation shown on the map is based on a computer model of waves generated by an event similar to the Balangoda Origin of the grid system is 200,000 metres South and 200,000 metres West of Pidurutalagala. ability to resolve some small-scale features of the onshore terrain including narrow waterways, and no warranties are made Village Name earthquake of moment magnitude 9.3 that occurred on 26th December 2004 in the Andaman-Sumatra subduction zone, which regarding the accuracy of the map nor the data from which the map was derived.Further, no field verification of model LOCATION may be considered as the worst-case scenario for any part of the coastline of Sri Lanka. The model used is the Cornell Bridge / River / Stream / Canal NAGODA D.S.Div. Name simulated extent of inundation has been carried out Multigrid Coupled Tsunami Model (COMCOT) which solves the non-linear shallow water equations on a dynamically coupled Tsunami Hazard Map system of nested grids using finite difference numerical schemes. Tsunamis are rare events, and owing to the paucity of known occurrences in the historical record, this map includes no Tank 10 Bathymetrical Contour / Value information about the probability of any tsunami affecting any area within a specific period of time. While this tsunami hazard Published by The bathymetric and topographic data that were used in the tsunami models comprise three nested grids.
