[TowerTalk] Tower Stress in a quake?

[Mike & Becca Krzystyniak]

Recently the public outcry on this caused Irving TX area to have more
sensors deployed to monitor what is going on (by TX-A&M I think...).

http://earthquaketrack.com/us-tx-irving/recent

All are at least 2X below the Barnett Shale (about 2.1km down), and more
importantly, I'm not sure the shale makes it that far east.
You have to admit looking at the data, something is going on...

As I am moving to new QTH which is near the epicenter for the largest one
recorded this year in NTX, I too am wondering about snapping tower guys
under tension or that "bump" snapping a cable on the crank up.

Those aren't exactly unbiased websites!

The fact of the matter is that there will be debate for a long time over the
issue. Until the incidence of earthquakes occurring AT FRACKING DEPTH goes
up a meaningful amount, it will continue. Most earthquakes take place far,
far deeper in the earth than fracking depth. As was stated earlier, there
most be faults to allow plates to shift along one another for there to be a
quake.

Will we see more sinkholes around fracked areas? That seems a more likely
outcome, if there is any negative outcome at all.

My few pennies' worth.
