I was wondering since that today 2/28/01 a 6.8 magnitude earthquake at Seattle area. Do you think IF earthquake happened in California Home of DCA,PGA,SFMW,KBF,DisneyLand,Universal Studios, etc. Rollercoasters will be damaged or destroyed? The recent earthquakes in California in 1989 San FRancisco Earthquake and 1995 Los Angeles Earthquake. I hOpe not but please tell me if it will
No, coasters can not really be damaged in the case of a "normal" earthquake. They build them specially in parks like Six Flags Magic Mountain because they consider earthquakes before building their coasters. I'm sure, if the earthquake was big enough, it could damage it some. But if it's just a normal earthquake, you would just feel a little shudder on the lift hill and if your were on the course already when it happened, you wouldn't notice it at all.

An earthquake could damage a coaster, but all coasters are designed to flex a bit, and it would probably take the ground beneath the coaster litterally ripping open to really damage one. ------------- 2001- the year of flight!
Hey Earth quakes are a real threat especially at parks were you would least expect them to occur at . It s a extreme threat with Woodens. ------------- Golioath Rocks the west but Millinnium Force Rules The Rest
Anything could be damaged by an earthquake, it just depends how server of an earthquake. If you think about it, a coaster is basicly nothing but a support strucure, so you realy wouldn't have too much to worry about.
I'm no engineer, but consider how much coasters "give" in the first place. Like high-rise buildings, they're supposed to sway and move a bit. When Mantis comes down after the vertical loop I think about how much the track flexes, or Space Spiral sways in the wind.
In other words, I think most could take a good beating.

I'm a mechanical not a civil engineer, but I suspect that a steel coaster would would probably have its design limited by wind load rather than earthquake. A woodie would probably be more vulnerable due to more mass located high up. Of course one small design detail done wrong could result in the failure of a coaster in a quake.
Well....Ninja and Batman were damaged at Magic Mountain when the Northridge quake hit in 94. Batman was still being built at the time. I think the concrete of a footer cracked. Something minor along those lines. The problem was fixed and the ride opened on time. Ninja had a little more damage, but, again, nothing big. The track in one area got a little messed up. The exact area escapes me at the moment. But, I hear that you can tell that it was tweaked. Oh, and get this, it bad the ride better. Go figure.

i know theres some sort of code in CA that wooden coasters have to have more wood. look at ghostrider that things structure is pretty big. i also know that deamon grizzly tidal wave and other rides survived the 89 earthquake in SF.

The damage from a earthquake is typically limited to the follwoing:
1. Old Construction 2. Ground liquidation 3. Other objects
If it is an old coatser, perhaps some damage woudl occur. Think of an earthquake as a wave in the ocean. Everything (Such as boats) on the ocean rides and falls. The same occurs on land, unless such a ride were directly on a collapsing falt line, or in the case of a weak hillside the gound liquifies.
