no link between tides and quakes

A very definite and sweeping statement about a "science" that most geologists (like my bro-in-law) will tell you is an art. Predicting earthquakes that is.

In these contexts I invariably point to friction and notably stiction. If you want an old mechanical instrument to overcome that last bit of uncertainty what do you do? Lets take the familiar barometer. Do you tap it gently and see if there is any minor change? Or on lathes add vibration, commercially? Even with lubrication abounding.

Now could we look at a fault line? And by magnification compare it to two metal surfaces rubbing against each other. Those surfaces look similar to the imagined fault line (which can be 50 miles wide). So a low pressure area lifts the water, and after it has gone the water rocks in a second order oscillation decaying exponentially in amplitude. An effect well seen in Lake Michigan because of the shape thereof. Timescales are days and weeks.

Hence that tap tap from about three major hurricanes. And an earthquake waiting to happen. All it needs is to exceed the current threshold.

And isn't one proposed solution (on the San Andreas) to large quakes to pump water into the fault line to lubricate it? Thus causing more frequent and less devastating ones.

Not proof, but a reasoned scenario cf sweeping NO.

ever sat as a weather front arrives? I have and on my timescale - relatively modest though it may be it goes "BANG"!
