1. Migrating liquids within the earth lubricate faults, causing slippage. The liquids can be tiny amounts of the remaining preflood subterranean water or magma produced by frictional heat that melted rock.
2. A large block, bounded on all lateral sides by faults, is sometimes lifted on one or more sides by a growing amount of magma forcefully injected below. Examples include the blocks that comprise plateaus. On a much larger scale are blocks as tall as the mantle is thick, bounded by thousands of faults that extend through the entire mantle. These blocks are precariously wedged (locked by friction) against adjacent blocks. Magma draining down these faults and into the outer core slowly increases the volume of the liquid outer core, so periodically the least-locked mantle block will be suddenly lifted. A disturbance large enough to vertically shift one weakly anchored block can suddenly shift—and frictionally heat—adjacent blocks.
3. Frictional heat generated by slippage along a fault will increasingly melt, deep within the walls of the fault, mineral grains with the lowest melting temperatures. The solid rock encasing the liquid droplets is stretched by expanding droplets above the crossover depth and compressed by shrinking droplets below the crossover depth. As heating within a large volume of rock increases, more liquid droplets form, merge, and eventually escape along faults. The remaining solid rock may collapse as an earthquake, while the slow drainage allows continental movement,...
If piezoelectric minerals, such as quartz, are among those stressed, voltages can build up for hundreds of miles around what will become the impending earthquake’s point of origin (the focus). Such voltages and the resulting electromagnetic effects are known earthquake precursors. They are even detected in the ionosphere, about 40–600 miles above the solid earth.
In other words, researchers now know that there can be significant electromagnetic signals in the ionosphere directly above a future epicenter and, at times, large heat emissions nearby, all a few days before a major earthquake;: by Dr. Walt Brown
