[Station owners: ACOE, U.S. Army Corps of Engineers; BECH, Bechtel Power Corporation; CLA, City of Los Angeles; GLDN, U.S. Geological Survey, Golden, Colorado; JCG, JCG Finance Corporation of America; MANC, Municipality of Anchorage, Alaska; MWD, Metropolitan Water District of Southern Calif.; OWNR, Owner of building; UCB, University of California at Berkeley; USGS, U.S. Geological Survey; VA, U.S. Veterans Administration. Instrument trigger time in minutes and seconds after the hour listed in earthquake column. Trigger time in brackets is a P-wave arrival time as event occurred while instrument was operating. S-minus trigger denotes i-wave-arrival-minus-1rigger-time (i-1) or i-wave-minus-f-wave-arrival-time (i-~, in brackets) interval. Direction is of case acceleration for upward trace deflection on accelerogram; horizontal components are listed as azimuth, and vertical components as "up" or "down." Maximum amplitude is peak acceleration recorded at ground level on one verticaltind two orthogonal horizontal components unless otherwise noted. Duration is interval between first and last peaks of acceleration greater than 0.10 ~-]
