Company Offers Disaster-Proof Storage For Records
Makarand writes "The Atlanta Journal-Constitution is reporting that a Utah company,
Perpetual Storage, is
offering
disaster-proof commercial storage space
deep inside a granite mountain
for companies looking to store their most important records.
The company claims that their vaults are protected
and safe from "any force known to man", including a nuclear blast.
The vaults have gained popularity
recently after hospitals, government agencies and universities have started using them to keep
their computer records safe."
Arrgh, armchair geologists getting modded Insightful.
Granite forms at depth in the crust, not in volcanos. It is typically indicative of igneous activity a long time ago -- sometimes billions of years. Its presence is not any kind of indicator of potential for volcanic activity.
When it is exposed at the surface, it usually indicates there has been tectonic activity that moved it upwards. Again, may have happened a long time ago.
In the Salt Lake, there is extremely low potential for volccanic or other igneous activity. What Utah DOES have is a potential for strong seismic (earthquake) acitvity. How safe things are getting bounced around by a magnitude 7 is a matter of question. Would depend on how well engineered the structure is to isolate it from ground movement. Building structures on solid rock is more easily engineered that unconsolidated materials because there is no potential for liquifaction and the high-amplitude, low frequency surface waves (Lova, Rayleigh) are not much of a design factor.
Building inside a granite mountain is a pretty good choice for isolating a structure from seismic waves. Just requires a good isolation system.
