The west coast never stops shaking, but lately the shaking has gone to an entirely new level, and this has many people deeply concerned about what may be coming.  Last summer, a series of alarming foreshocks immediately preceded the two historic quakes that shook the Ridgecrest area in southern California.  But those quakes were nothing compared to "the Big One" that scientists assure us is way overdue.  Someday an earthquake that is hundreds of times stronger will absolutely devastate the California coastline, and it may be arriving a lot sooner than many people think.  Farther north, the Cascadia subduction zone is a ticking time bomb that could literally unleash an unprecedented disaster at any moment.  What I am talking about is an event that will completely wipe out entire cities and that the region will never recover from.  As I have detailed repeatedly, authorities have warned us that "everything west of Interstate 5 will be toast" when an absolutely massive seismic event along the Cascadia subduction zone sends a gigantic tsunami sweeping inland.
