Get ready for some shaking and rolling. A retired Bay Area geologist who predicted the 1989 Loma Prieta earthquake, says the next big one could hit this week.
Jim Berkland believes a 3.5 to a 6.5 magnitude earthquake will rattle somewhere in the northwest between March 19 and March 26.
He says telltale signs include the moon's close distance to the earth, extremely high tides and magnetic field changes affecting marine animals.
A USGS spokeswoman says scientists have studied Berkland's theories and associations, but they have not found them to be mathematically correct.
Berkland is known for saying just before the 1989 World Series in October that a significant quake was near.
The former U.S. Geological Survey geologist was then suspended for two months for making predictions on work time.
