Record rainfall causes major floods in Japan

Over the last few days, areas of Japan have suffered major flooding caused by the largest amount of rainfall in 24 hours the country has ever seen.

Causes

  • Over 100 mm of rain was reported in some areas in just one hour alone.
  • Kumamoto and Oita prefectures, experienced over 500mm of rain in 24 hours.
  • July is the wettest month for the island of Kyushu. However, they would normally receive around 340mm of rain in the entire month. On Wednesday, some parts of the island received that amount in 4 hours.
  • The ground is already saturated. As a result, the excessive rainfall has not be able to soak into the soil, which has led to these flooding problems.
  • Kyushu is very mountainous. As a result, the hillsides have become saturated leading to landslides
