Natural phenomena such as earthquakes, tsunamis, and floods themselves do not kill people. However, they do cause disasters because people live in them. People have the instinct to avoid hazards through the five sense organs: eyes, ears, nose, tongue, and skin. The most effective way to detect hazards and avoid disasters is to visualize them. Mountains are covered with trees, and rivers and oceans are covered with water, making it impossible to see their original shapes. We aim to contribute to the protection of people's lives from natural disasters and the creation of a safe and prosperous country by visualizing and diagnosing hazards in coastal, river, and foothill slope areas where many people live, and by proposing prescriptions that are suited to each region.
