Volcanic gas disasters around active volcanoes all over Japan have occurred 27 times and 45 people have been killed since 1950. Configuration of the ground near fumarolic areas and weather conditions are the principal factors in gas accidents. Making gas-hazard maps, setting of restricted zones and installation of automatic alarm system with continuous monitoring are effective measures to prevent volcanic gas disasters. Knowledge of toxicity of volcanic gases and first aid are also helpful in reducing volcanic gas disasters.
