Nothing on Fark ever goes to waste.  This won me a PS contest in 2007.

Ivo Shandor: 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.

Actually, if you check back in the historical record you will find that the vast majority of large earthquakes happened within 2 weeks of a new or full moon.


I see what you did there.

bingethinker: SmithHiller: Word on the street says Two strong Planetary Alignments (Mars-Earth-Mercury on April 15-16) and (Mars-Earth-Uranus on April 21-23) feature prominently this month may coincide with significant earthquakes to be registered at high latitudes (Alaska, Norwegian Sea) between 7.0- 7.5 Magnitude on either April 15 or 16. The second time frame covvers April 21-23 where the forecast isolates the Indonesian region for a possible 7.2-7.7 Magnitude earthquake.

The we must get to the rocket! Flash is our only hope! Zarkov, start the engines!

Rent Party: And Cascadia is ready to pop open soon.


Geologically "soon", which could be today or 300 years from now.

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


I am not a seismologist so I can't be certain and this is based on what I have read over the years, but I believe it is the stored up energy and stress that is built up that is then released when it is fractured over a larger area.  Remember these faults are miles and miles deep and taking the stress billions and billions of tons of material that should be gradually moving, but is instead locked up.  When an earthquake allows this stress to suddenly release and moves all this this pent up energy along a long segment, this energy is translated into the shaking.  So the longer the segment that ruptures and releases the stress, the larger the earthquake that is possible.  Of course not all segments of a fault are locked up so the release all depends on what segments are storing this stress and which ones are moving freely.  The exact ability to store also depends on the type of fault.  Subduction zones (one plate going over another like off of Chile, or Japan or near Seattle) tend to have more potential for larger earthquakes as they lock more frequently.  The San Andreas fault is a strike-slip so the plates are moving beside each other that has less potential for the larger quakes.

I ate a bowl of chilli with Dave's Scorpion Pepper sauce for lunch. So I too am worried about earthquakes and a ring of fire.
