A megathrust earthquake, magnitude 9.0 or higher, is possible, and a newly discovered hole in the Pacific Ocean holds the clues! The hole is leaking, and that appears to be a sign that conditions are lining up for a powerful earthquake. Of course, if that were to happen, it would cause a potentially catastrophic tsunami. But knowledge is power!

The hole, discovered by a University of Washington research team, could be a vital clue in predicting earthquakes.
