Earthquakes, which affect our lives a lot especially in various natural disasters, are still difficult to predict when they occur. Therefore, because earthquakes are phenomena that occur underground, we decided to search for a clue of them by paying attention to the change of ingredients of water. Following the previous research, we decided where to take samples, and did regular sampling. Also, as a new trial, we increased the number of places to take samples, and gather samples more regularly in this research. We analyzed the data by using an ion chromatography analyzing device. By consecutive research, we figured out that the rate of ion concentration tends to rise before earthquakes occur, and tends to fall after they occur.
