SPIE: On Shaky Ground

A new generation of ‘extremely large’ telescopes is being built in earthquake-prone areas. How will engineers protect these massive machines?

“We believed we could resolve our seismic challenges without an extreme measure of seismic isolation,” said GMT project designer Dave Ashby. “It’s actually a pretty compact design. However, once we actually started to explore the risk exposure in a quantitative way, we rapidly came to the conclusion that that wasn’t practical.”
