Earthquake Trivia: How many earthquakes occurred in Japan each year?

Japan is a country with frequent volcanic eruptions and earthquakes. In 1792, a volcanic eruption occurred in Japan, killing 15,000 people; in 1923, the Great Kanto Earthquake in Japan killed 130,000 people and the country suffered heavy losses. Why are there many volcanoes and earthquakes in Japan? It turns out that the Japanese archipelago is located at the junction of the Asia-Europe plate and the Pacific plate. According to the geological plate theory, the Pacific plate is relatively thin, with a relatively high density and a relatively low position. When the Pacific plate moves horizontally westward, it subducts beneath the adjacent Eurasian plate. Therefore, when the Eurasian plate collides and squeezes with the Pacific plate, the rock layers at the junction of the two plates will undergo deformation, fracture and other movements, resulting in volcanic eruptions and earthquakes.

Japan is an island country with 83 large and small active volcanoes, accounting for one-tenth of the world’s total active volcanoes. At present, nearly one-quarter of Japan’s land area is covered by volcanic eruptions.
In addition, Japan has not only many volcanoes, but also the number of earthquakes. According to statistics, there are thousands of earthquakes every year in Japan, including 4 times per day for magnitudes above 3
