A volcano that grows taller in the rain? Mount Fuji has been hiding a geological secret
Mount Fuji's ground is swelling up to two centimeters during heavy rains, a phenomenon not linked to magma. Scientists discovered that porous rock layers beneath the volcano act like natural sponges, absorbing rainwater and causing temporary inflation. This discovery helps distinguish between weather-related ground movement and genuine volcanic threats, improving risk assessment.
