Yeah, the clicking fingers are finally loosening up. I cleared a dollar yesterday, so I shall elucidate this concept.
Over in Vancouver, they are regularly having this 'silent slips', accompanied by earthquake tremor. Acts just like the geysers on the Rising Yellowstone SuperVolcano. (the people now raise their arms, run around and scream like chickens)
Now, they have finally figured out that this is caused by water. The water gets trapped, builds up pressure, and releases. Scientists haven't progressed to the point that water is involved with other types of earthquakes, but they're getting there. So, I chalk this up in my Water ==> Earthquakes column.
