Hi Dr. Don. An explanation if you please. Below is a chart of quakes that could have been felt in the US from nearby countries.

As an example. The M>3.6 quake in Central California has a latitude of 72N and a Longitude of 121.09W. This isn’t Central California. It’s in extreme Northern Canada, or am I reading this wrong. There appears to be some errors with the latitude of other locations. Take Care…Don in creepy town
