2004 tsunami
The tsunami generated by the Indian Ocean earthquake of 2004 inundated much of the area and partly damaged the lighthouse that subsided 4.25 m in the tsunami. As a result of this subsidence, the coast retreated and the sea permanently came inwards. The lighthouse has been made functional since then.
The base of the lighthouse was 5 m above sea level when constructed on 1972 to until the tsunami. After the tsunami, the sea rose and the base was less than a metre above the sea level showing a subsidence of sea floor by over 4 metres. It has observed that the sea is slowly starting to retreat back partly to its original position and the subsidence has decreased as the ocean floor is slowly bouncing back partially.
