When an earthquake occurs, rocks in a deep fault break and slip against each other, and energy is released into the earth's crust. This energy radiates as seismic waves (that's the earthquake we feel) and also heats and fractures the rock. The new fractures can help channel fluids from deeper crustal levels up to the shallow zones where they deposit minerals. Some of these deposits are economically important ore bodies.

当地震发生时，深断层中的岩石破裂并相互滑动，能量被释放到地壳中。这种能量以地震波的形式辐射出去（也就是我们能感觉到的地震），同时也会加热和破坏岩石。新的裂缝可以帮助流体从更深的地壳层流向浅层，在浅层沉积矿物质。其中一些矿床具有重要的经济价值。
