Its effect can be seen from the increase of Hs up to 6.2 m with an associated
Tm up to 13 s in a water depth of 20 m.
Cyclone Thane, with the strength of a Category 1 hurricane of 65 knots
(120km per hour), struck south eastern India on December 30, 2011. Thane
hit the coast of Tamil Nadu as shown in Fig. 3.21, and made landfall

79°45ZE). Thane, commonly referenced as a cyclone instead of a hurricane
or typhoon, formed in the Indian Océan on December 25, 2011.
