Tsunami inundation study at Pulicat

The present study has generated  results helped to carry out tsunami vulnerability assessment. Map represents the submergence level of study area from 0-10 m. If the water level rises from 0-0.5m can cause submergence along Pulicat settlement, jamilapath and saathankuppam village. These two areas are highly prone to inundation. And near to the mouth region is also submersible when the water level rise as 0-0.5m. If the water level rises from 0.5-1 m can cause submergence extended to saathankuppam village and Pulicat settlement and mouth region. If the water level rises up to 1-1.5m, the region adjutant to the back water of Pulicat and saathankupam village, karimanal village can be easily submersed.

The Pulicat market area, area adjustant to jamilabath settlement, sathankuppam and vairavam kuppam area can be easily submersed if the water level rises to 1.5-2m. If the water level rises up to 2-2.5m it would cause inundation along the saathankuppam and some of the Pulicat region. If the water level rises up to 2.5-3m which causes inundation along the settlement area of light house kuppam and some of the settlement area of saathankuppam. If the water level rises up to 3-3.5m it makes inundation along the land area of Pulicat and area which is near to the lake in Northern side. 3.5-4m water level rises can cause submergence along the Pulicat and in adjustant to lake and lighthouse kuppam. 4-4.5m of water level rises can cause inundation along settlement area of Lighthouse kuppam. If the water level rises up to 4.5-5m, the karimanl village and the Nakathur village would be submerged. 5-6m water level raises would inundate along the Nakathur village.  6-7m, represents the submergence level adjustant to Nakathur village. If the water level rises up to 7-7.5 m which cause inundation near vairavam kuppam and 7.5-8m water level rises can inundate the settlement area of vairava kuppam. If the water level rises up to 8-10m, the Vairavan kuppam and adjutant to karangali village can be easily submersed. The highly elevated area was observed in vairavam kuppam and the lowest area was noticed in saathankuppam and jamilabath village which are highly prone for the tsunami waves. These villages can be easily submerged even if the water level rises up to 0.5m.
