Maybe I'm way off here but does it seem to be a good thing. The brine lubricates the faults and instead of the pressure building until there is a huge earthquake you get many smaller ones.
No, no. I agree. Here in the Midwest, there is a lot of talk about the New Madrid fault, which is famed to have produced a 9.0 (or greater) earthquake so strong that it reversed the Mississippi and rang church bells as far away as Philly (I'm sure you know this, Pogo).
for a quicky review of the fault.
One of the big problems, they say, is that built up tension results in bigger earthquakes. The fact that New Madrid was due for a quake over two decades ago is source for a bit of angst here in the Midwest because the longer we go without one, the worse it will be when it finally happens.
