The base of the lighthouse was 5 m above sea level when constructed in 1972. After the tsunami, the sea rose and the base was less than a metre above the sea level, showing over 4 meters of sea floor subsidence. It has been observed that the sea is slowly retreating back to its original position and the subsidence has decreased as the ocean floor slowly bounces back partially, a similar drop and rise due to crustal de
