Shake Test Follow up: Here’s what Happened in San Diego

16 May 2023

As you may have read in last week’s issue, last Tuesday (USA time), the researchers simulated two of the largest earthquakes in recent decades — the 6.7 magnitude earthquake that struck Northridge, California, in 1994, and the 7.7 Chi-Chi earthquake that struck Taiwan in 1999 and killed more than 2,400 people. First they “played” the Northridge earthquake on the simulator for five minutes before turning to the Chi-Chi earthquake, watching the building all throughout the process. What scientists discovered after simulating an earthquake on a 10-story wood building – the building was “dancing” underneath the simulator, they said.

Tallwood “danced,” Shiling Pei, associate professor at the Colorado School of Mines, told ABC News. It’s a sign the construction was a success. “The building moved around just like a tree in a windstorm,” he added.
