The state is currently in the midst of Tsunami Preparedness Week where experts are looking to highlight the risk of a devastating huge wave.
Just off the coast of California lies a fault known as the Cascadia – which is up to 30 times more powerful than its more famous neighbour, the San Andreas fault.
The difference between Cascadia and San Andreas is that the former is a subduction zone, where plates lie on top of each other, whereas in the latter they sit diagonally.
As a result, subduction zone faults can cause much more damage.
Chris Goldfinger, professor of Geophysics at Oregon State University told CNN: “The Cascadia fault can cause an earthquake with almost 30 times more energy than that of San Andreas and then generate a tsunami that San Andreas can not create.”
The last time the Cascadia fault rumbled was in 1700, causing a tsunami to occur in California.
