Berkland is, to say the least, a controversial figure in geology. However, this is because he steps out of the standard theories and makes assertions based on his own theories, not because he’s an out and out crank. In this video, Neil Cavuto only mentions his hit on the ‘World Series’ earthquake of 1989, not his various misses. Still, he is worth listening to, if only as a reminder to everyone up and down the west coast to get their earthquake kits ready. What he doesn’t mention is that there have also been a couple of gamma ray bursts from deep space impacting the planet in the last few weeks, the last one yesterday. So we’re taking a lot of energy on from the outside: solar activity, a supermoon on the 19th and gamma ray bursts. The problem is, nobody really knows if these things have all that much of an effect. What is now known, though, is that there is a complex relationship between fault lines, and quakes in one fault can indeed lead to quakes in another. It is also known that the Cascadia fault off the Pacific Northwest is not stable. It could produce a great earthquake and a tsunami. Further south, the San Andreas and its attendant system of faults are in a permanent state of instability. They could produce a quake in the 7.0-7.5 range, but no tsunami. The only known fault large enough to produce a tsunami off the Southern California coast has been dormant for 5 million years and is not presently generating any activity.
