Dutch was very convincingly linking fracking, and hydrothermal drilling with earthquakes. He very convincingly laid out the facts, if you drill tens of thousands of holes into fault zones, it obviusly makes a weak point and the earthquake energy seeks the path of least resistance. He further hypothesised that mining and geothermal operations are likely to blame for the activation of a long dormant fault (the Garlock fault) he showed graphically how the quake energy was unzipping the Garlock almost all the way to where it ties into n to the San Andreas.

“Scientists are baffled” at why the long dormant Garlick fault has reawakened (newspaper article la times after the ridgcrest quakes at china lake)

There is no question in my mind, that Dutch is correct and they had no choice but to silence him. The big one on the San andreas/socal is likely imminent, and the oul/gas industry is worried they could be liable.
