I have had a similar dream.

Also note that on 9/29/09 there were 3 large earth quakes that happen at the same time a 8.1, 7.8. and another 7.8 along the Tonga trench.

From [link to unews.utah.edu] There's much more info on that site about the quakes if your interested.

"August 18, 2010 - A magnitude-8.1 earthquake and tsunami that killed 192 people last year in Samoa, American Samoa and Tonga actually was a triple whammy: The 8.1 "great earthquake" concealed and triggered two major quakes of magnitude 7.8, seismologists report Thursday in the journal Nature.
"At first, we thought it was one earthquake," says study co-author Keith Koper, director of the University of Utah Seismograph Stations. "When we looked at the data, it turned out it wasn't just one great earthquake, but three large earthquakes that happened within two minutes of one another. The two quakes that were hidden by the first quake ended up being responsible for some of the damage and tsunami waves."
In terms of energy release, the two magnitude-7.8 quakes combined "represent the energy release of another magnitude-8 quake," says Koper, a seismologist and associate professor of geology and geophysics at the University of Utah. "It was essentially a great earthquake that was triggered. It was not some silly little aftershock."
Another study in the same issue of Nature reportedly refers to the two 7.8 quakes as a single quake. "I realize it looks inconsistent, but sometimes two events that occur quite close in time and space are considered a doublet, or two pieces of one earthquake," says Koper, who came to Utah this year from St. Louis University.”
“The most important scientific aspect of the quakes was their unprecedented pattern, Koper says. In technical terms, it is the first known case of a large "normal" fault earthquake (the 8.1) occurring on a plate of Earth's crust beneath the ocean, and then triggering major "thrust" quakes (the 7.8s) in the "subduction zone," where the oceanic plate is diving or "subducting" beneath a continental plate of Earth's crust”

All three earth quakes happened at about the same time (within seconds of each other) and within 40 to 80 miles of each other. It was quite a weird shake that started with a long buzzing vibration period before the main waves hit then all hell broke loose.

In my dream it will happen again. But in that dream I'm no longer on Island.
