The application of the fractal geometry in the study of sea-floor volcano

A fractal dimension measurement was made to the contours of the sea floor volcano of the South China Sea in this paper. It was found that the contours of the volcano end there are have stable fractal dimensions in its vicinity. The topography of the volcano end its vicinity can be divided into three parts by using fractal dimension:the mouth of the volcano, the steep waist part of the volcano end the plane sea floor near the volcano. Their fractal dimensions are about 1.12 which are lower than those of the lend. This points out that the basalt volcano has scale inflexibility even it is not very old, and it will have a fractal dimension with little difference after received some marine deposit.
