Natural disasters and disaster prevention in Geoparks

The Japanese archipelago is one of the most disaster-prone regions in the world.
Despite making up just 0.25% of the Earth’s land area, Japan experiences about 20% of the world’s earthquakes with a magnitude of 6 or higher.
In addition to earthquakes, the country has faced a wide range of natural disasters, including volcanic eruptions, flooding, landslides, and heavy snowfall.
Due to the unique geological and topographical features of the islands, many areas within Japan’s Geoparks have a history of large-scale natural disasters.
Through the Japan Geopark Network, visitors can also learn about disaster preparedness and prevention.

Nihonkai-Chubu Earthquake, which occurred on May 26, 1983, had a magnitude of 7.7 and triggered a tsunami over 10 meters high, claiming the lives of 107 people.
In Oga City, a group of elementary school students on a field trip were swept away by the tsunami, and a total of 23 lives were lost.
In Ogata Village, although there were no casualties, significant damage occurred, including the destruction of levees, the collapse of bridges, and liquefaction of agricultural land.
At the Oga Peninsula and Ogata Geo park, a memorial for tsunami victims has been registered as a Geo-spot, and at the visitor center, hazard maps and various exhibits are displayed to raise awareness and encourage caution.
