Those Highs seem easily capable of crossing the US in a day and an
half to two days. So expect another 2 or 3 more Magnitude 6 quakes
before the next spell.

As you can see there is a major problem uising this method to forecast
earthquakes. First off there is the scope of the chart.

It aught to cover at least 120 degrees of the planet and most of the
hemisphere. Just having Canada and Mexico included would be a big
help.

With them included, the Atlantic Chart can become more transparent.
