Lowell would be talking about the following, but is not posting lately-there have been in my qualitative opinion a lot of "intraplate" earthquakes in North America the last 10 days or so. The latest is the largest-a M4.5 in northern Quebec today. Roger if still looking for something to do can see if any of these are lining up along a small circle. I'm seeing these on the near real time earthquake page-neic.
