Disaster Types and Measurements - INI

Japan is one of the world's most disaster-prone countries, experiencing various natural disasters including earthquakes, typhoons, floods, sediment disasters, volcanic eruptions, and tsunamis. This data systematically organizes these disaster types and the measurement indicators defined by agencies such as the Japan Meteorological Agency, Fire and Disaster Management Agency, and Ministry of Land, Infrastructure, Transport and Tourism (seismic intensity, magnitude, typhoon strength and size, water levels, alert levels, etc.). It serves as a useful resource for disaster prevention measures and understanding disaster risks.
