Ko tapu is limestone (Limestone) with perfect female age age mountain (Permian), or approximately 295-250 million years, since the limestone is soluble due to corrosion properties easily. Therefore, the island in the Phang Nga Bay, it has a strange shape, and there are many variations depending on the ruins of a destroyed stone flesh decay.Origin of Koh Tapu is related to the ancient sea-level changes. The original Koh Tapu island and he leaned the East junction with the same conditions as, and on the land. The movement of the crust at a later time Cause there is a long horizontal scroll, you don't lose through Phang Nga Bay West. Called a fault this fault Marui Canal causing smaller joints that move followed the fault he leaned up and crack fault found in the limestone islands, etc. In addition, a fault causes the ruins of stone in the area of the seam between his nail and he leaned on the East side. Make him nail his distinctive ball is extracted.The land was a nail, and he has been influenced by seawater that spanned into the pot during the last 10000 years ago, approximately makes it possible for him to live in his area and nail conditions is. He pointed at the head of a nail, by filing out into the sea. Later, Hua Laem is wave erosion and refined until it has tapered shape and lacking from his leaning markedly East. There is the famous stone island.The maximum rise to approximately 6000 years ago, the current level is higher than the level of approximately 4 meters of sea water fluctuations have caused erosion Koh Tapu as water erosion concave stone joints to such levels. Later, the sea level fell down at about 2.5 meters of altitude from the sea level. The new sea level have been eroding the bottom of a water Koh Tapu, new rock erosion and is a level khot and bath area with living things such as shells, phriang Island, inhabited by around to salvage the oysters have caught in the joints this erosion to age by means of carbon.Radiation (C14) is age 50 years and shows that the 2620 + khot KIO, caused by erosion of sea water to approximately 2500 years ago. Since then, sea water, thus reducing the current levels are down. Part of khot KIO happens when 2500 years ago. Make Koh Tapu and striking characteristics is a famous tourist destination of the country.Ko Tapu has problems with erosion caused erosion erosion of sea water. Rock drilling to the housing of animals such as oysters. Phriang, crab, etc., the strength of wind waves in the monsoon season. Changes in Earth's environment due to the greenhouse effect, the reaction may wind waves change speed and finally to human activities, such as interference with the mooring anchor mooring to be left behind by the around the island, including a wave of long-tail boat that runs around the island.
