Hurricane Harvey flooding forced Earth's crust down by 2 cm
Hurricane Harvey, the most powerful storm to hit Texas in over 50 years, flooded Houston with an estimated 125 trillion litres of water, causing the Earth's crust to deform and sink by two centimetres in the area, US-based geologists have revealed. Notably, the crust is a solid layer of rock which lies above a partially molten layer called upper mantle.
