I do this once in a while for new people to my 'Earthquakes' g+ collection. Up here in Canada, we have the Precambrian rock emerging, and we have studied it a lot.  It plunges to be below all the sediments of the US.  There hasn't been one speck of study for the 'basement' in the US, yet that is where the earthquakes are.  The pc isn't one huge slab of solid rock, but has a complex

It hasn't really rained for a month, so anybody can do anything to a slope.  Without water we'd get no landslides or earthquakes.  Of course, we wouldn't be around to celebrate.  :) This was yesterday, and today it's exactly the same.  A very nice geological exposure.  I really think they can be done and gone before it rains

This weekend I suggested that the earthquake swarm in northwest Arizona might have come to its end. We had not recorded any events for a week. But last night at about 9 p.m. local time, there was a magnitude 1.3 quake in the swarm area.  [Right, orange star marks epicenter.

Now, I'm only doing these for my retired colleagues, so they can have a laugh.  I was the last paid geotech engineer in Ontario, and I had to quickly go to earthquakes when all infrastructure builds ended.  As well, with cloth and tensar it became child's play to put up a retaining wall, which was the hard-core geotech's bread and butter.  There are no tricky foundations in Ontario, and
