There is a lot of seismic activity with the North American Plate. Do I see a pattern that might predict any further seismic activity in Haiti?
The problem with the earthquakes of the North American Plate is the depth of the quakes. They are occurring in less than 10 kilometers of the surface and that is common of this plate.
I believe it would be imprudent to any rescue effort to think the worse is over. This might be just the beginning.
Rebuilding can probably proceed within a strong earthquake area, but, it has to be done prudently and with the thought it is a very unstable area people are working in.
