CMSB - Cal Memorial Stadium, Berkeley, CA, USA. Although Friedman describes Memorial Stadium as an “engineering challenge,” he has confidence in his response. While solving the issue of accommodating surface rupture was an immense engineering challenge, another weighty task also dominated the design of the stadium: the design of a two story, 375 foot long press box that hovers above the seating bowl.

A map from the United States Geological Survey shows the quake hit just east of the California Memorial Stadium. There are however special seismometers which can be placed deep into water filled boreholes. The quake hit at 6:32 a.m. along the Hayward Fault with a … Built on the Hayward Fault, the walls of the facility began to separate, and the stadium received a “poor” earthquake rating in 1998. The Berkeley Digital Seismic Network (BDSN) is a regional network of very broadband and strong motion seismic stations designed to monitor regional seismic activity as well as provide high quality data. The University decided to renovate rather than destroy the stadium.

At Memorial Stadium at UC Berkeley, seating was recently broken up and rebuilt so that the facility’s western half could move 6 feet northwest from the other side.

Typically seismometers are placed in small concrete vaults directly on or at a maximum of a few feet below the ground.

(b) The Alquist-Priolo Earthquake Fault Zoning Act (Chapter 7.5 (commencing with Section 2621) of Division 2 of the Public Resources Code) shall not apply to the California Memorial Stadium located on the University of California, Berkeley campus. They are of a slim, cylindrical design capable of withstanding several thousand pounds of water pressure. The station is named “CMSB” after the California Memorial Stadium. California Memorial Stadium 375'-long press box can sway up to 12" in a major earthquake. Originally opened in 1923, California Memorial Stadium at the University of California, Berkeley is on the US National Register of Historic Places.
