The magnitude 7.8 earthquake in Kaikoura New Zealand in 2016 caused over 50 landslides along State Highway 1, north and south of the Town. The team of engineers tasked with reopening the corridor to road and rail traffic […]
From the USGS Newsroom:
USGS scientist Ken Hudnut fills us in on how science created the theoretical magnitude 7.8 earthquake behind the Great Southern California ShakeOut—the largest earthquake preparedness drill in U.S. history, coming Nov. 13—and what such an earthquake would do to downtown Los Angeles.
Seems like they did it right wiith this study. They had multiple teams independenlty come up with the ground shaking model, then had different structural engineers who are experts in seismic design of large buildings review the tall buildings in the L.A. area for the design earthquake. They say that buildings would likely come down in the 7.8 magnitude event. Click through to watch the video interview from the USGS.
Early Sunday morning, a 6.0 Magnitude earthquake struck near Napa California lasting 10 to 20 seconds, sending 120 people to the hospital and damaging buildings, breaking water mains, disrupting power distribution, and breaking gas lines […]
