Itako-maimai Rock

Rock which "itako" flies

itakomaimai rock which rises to stand up from the sea is made from magma which spouted out by volcanic activity of the bottom of the sea. When magma got cold and froze, volume decreased, and there was regular crack (logic). Principle is the same as phenomenon to crack when this pours water into glass of glass which it heated. It is weak point of hard rock (here andesite), and this logic is gradually reduced by erosion of wave, and it is thought that there was reef of lone form in this way.
