bingethinker: All three planets are too far away to cause earthquakes. The moon has a greater pull on Earth than any of those, and I don't see anyone blaming the moon for earthquakes.
divgradcurl: CanuckInCA: Important part,The magnitude of an earthquake is related to the length of the fault on which it occurs -- the longer the fault, the larger the earthquake. The San Andreas Fault is only 800 miles long. To generate an earthquake of 10.5 magnitude would require the rupture of a fault that is many times the length of the San Andreas Fault. No fault long enough to generate a magnitude 10.5 earthquake is known to exist.Daedalus27: It is self limiting as the higher magnitudes become impossible as there isn't a continuous fault fracture of sufficient length to generate such a quake (at least based upon the present understanding of earthquakes). I think something like a 12.0 would require a quake from Seattle, all the way down the Juan de Fuca plate joining the San Andreas and then running down the length of California to the Mexican border. I don't know that it is possible given the way the faults line up and whether they could propagate all the way down but If that would somehow happen, the West coast, Hawaii, coastal Alaska and even the east coast of Asia would be devastated.okay, but why does length play such an important part? if it is all just a matter of coefficients of static and dynamic friction, and how much energy is bound up in the plates pushing against one another, couldn't equal magnitude quakes happen from 2 different sized faults?i imagine it to be like rubberbands. the distance i can get it to fly isn't based on how long the band is, but more on its elasticity and how much energy i can get into the spring./completely unscientific comparison//just asking questions
