~ NOTES:
~ Thanks to the GRACE Project which took gravity map images of planet Earth since 2001, It has been possible to predict which areas of the world are the most impending & vulnerable to earthquakes, (the reddest areas having greater gravitational density), however pinpointing the place & time is still questionable. For example the first gravitational map of Earth made in 2001 clearly shows the origin & path of the 2004 Somalia earthquake & Tsunami path, but its's event in 2004 was not predictably foreseen. Additionally, in the next gravity map taken later we can see how the reddest areas in South America are located where most earthquakes in that area have occurred since.
