Earthquakes effects on Roller Coaster

I know in California they have a lot of quakes, so what effects do they have on coasters. Do coaster company's do anything to make the coaster more stable or obsorb more shock. Has MM or PGA ever been through some pretty bad ones?

Rollercoasters in California are made..."special". Where they can be much more stable in the case of an Earthquake. I have a friend who lives in California and says if you were to be on the lift hill during one, you would just feel a slight shaking, but if you were already riding the course, you wouldn't notice it at all. So, you see, they make these things pretty stable for natural disasters.

A roller coaster has a very flexible frame just by its design it needs to take the jarring from the train. You can see this by just watching the supports as the train goes by. I think it would take a major earthquake to damage a coaster. I don't really see any difference in the way coasters are constructed in Cal vice maybe Kansas City Maybe larger footers. The only difference i see is if the coaster is built in wetlands or near water they are up out of the ground more.
I don't think that there is any difference almost any coaster could probably withstand a earthquake. They are all built very strong.

When Ghostrider was designed, seismic constraint was taken into account. This is why there is so much wood supporting this thing.

However, I believe that Psyclone at SFMM is not the same story. I have never ridden it, but I believe that part of the reason why everyone complains about how rough it is now can be traced to damage the ride received from an earthquake.
