In the dream I saw a map of what looks like the United States of America on a round globe with a huge USGS orange colored square box located in the far north northeastern section of the map. It seems as if the orange square box was located off-shore near the coast line, but this is not certain, the orange box could have been located on land. The orientation is definitely north-northeast.
The size of the box indicates an earthquake of up to 8.0 magnitude or greater. This could happen anytime soon from now to within the next two-three weeks - earlier is more likely than later. Northeastern regions such as Maine, USA and New Brunswick, Canada should take note. Rare possibilities might include Newfoundland, Canada or off-shore Shanghai, China (i.e., north northeastern China or similar situated north northeastern land mass) or the Kuril Islands north of Japan, but North American seem more likely.
