Munrothuruthu (‘Munroe Island’) is a place renowned for continuous settlement, in the Kollam district of Kerala. The Indian Ocean earthquake and Tsunami of 2004 triggered this major problem. The island is located at confluence of the Ashtamudi Lake and the Kallada River. Low lying regions of the island are facing progressive settlement which has become pronounced since the occurrence of Tsunami. The area has been affected by upward seepage of saline water during High Tide events, denoting the axial lowering of land mass.
