Huge parts of Antarctic and Arctic ice have already melted. Key Antarctic glaciers (Hektoria, Green and Evans for example) increased their melting rate 8 times in 3 years (between 2000 and 2003, Geophys. Res. Lett., 31, L18401). ...
Energy of earthquakes systematically increases. The graph on the left depicts the annual quake energy since record begun in 1973, computed on the basis of USGS scientific data from all quakes above 4.0 magnitude since 1973. The data is compared (scaled) to 1973 quake energy. The energy of earthuakes 7.0 and above increased 6 times in the same period...
The North American Plate is not stable. (click here) It has increased dynamics compared to any other tectonic areas on Earth. It has undergone isostatic rebound due to the loss of its ice anchor in the Arctic Ocean. I doubt if the seismic activity will stop and it is my estimation, due to its mass the other plates are 'in reaction' to it. It is only prudent Haiti be aware of potential activity.
Sincerest concern for all those in Southern California, as if California needed anything else to add to its already stressed fiscal status.
