The northern Cascadia
section of the San Andreas Fault doesn’t receive as much press as the section
near San Francisco. This fault is
off the coast from Vancouver Island to Northern California. There is the possibility of a
mega-quake of 9 lasting at least 5 minutes in this area. The intensity of this quake would cause
a massive tsunami and many smaller aftershocks. There have already been four earthquakes dated by excavation
of the soil in the nearby marsh.
One quake caused a forest of trees to die off. This fault area is called a subduction zone because a denser
oceanic plate is sliding under a less dense continental plate
This is not the
fictional disaster film with Dwayne Johnson but it is a documentary released by
the BBC. There is a lot of gloom
and doom in this film but it does offer a lot of information to think
about. The March 11, 2011, the Japanese
tsunami that damaged their nuclear power plant resulted from a 9.0 magnitude
earthquake producing a tsunami of 33 feet high. The epicenter of the earthquake was northeastern Japan. Debris from this event continues to wash
up on the coast of North American beaches. 3 1/2* (I liked this film)
