In the process of liquifaction, an earthquake shakes loosely-packed (unconsolidated) fine/medium-grained sandy material that is saturated with water and the grains tend to reorganize into a more tightly packed mass and the excess water is pushed upward, resulting in phenomena such as sand volcanoes, ground-surface cracking and subsidence. ​on the Earth's surface directly above the place in Earth's interior where the earthquake was generated (known as the hypocenter or focus of the earthquake). Rayleigh waves can move through the surface of both earth and water. If you have two chunks of the mantle, both of which are the same composition and are under the same pressure (because they are at the same depth) but chunk A is hotter than chunk B, how will their densities compare with one another?
