Volcanic Hazards

GSJ conducts field surveys, analyses and experiments to understand volcanic eruption history, which is effective for mitigating the impact of volcanic disasters. At the time of eruption, GSJ immediately dispatches an urgent survey team to volcanoes and publishes obtained data. Results of the surveys and analyses are integrated to compile geological maps of volcanoes and other databases.
