    Cambridge Core - Solid Earth Geophysics - Active Faults of the World - by Robert YeatsCited by: Zone 4 indicates the highest level of seismicity (see Figure ). Each zone was allocated a factor, or coefficient, from to ; this value was a multiplier representing the acceleration value for which the building was to be designed. These values indicate a fourfold range in acceleration values between Zones 1 and 4.

    Abstract. An overview of the most important developments in Engineering (or Strong Motion) Seismology is presented alongside Professor Keiiti Aki’s contributions, who is one of the founders of this field. The mechanics of earthquake rupture are discussed with due emphasis on the various physical phenomena. The presentation is made in a tutorial manner, borrowing freely from Keiiti Aki’s Cited by: The Whittier Narrows earthquake occurred in the southern San Gabriel Valley and surrounding communities of southern California at a.m. PDT on October 1. The moderate magnitude blind thrust earthquake was centered several miles north of Whittier in the town of Rosemead, had a relatively shallow depth, and was felt throughout.

The largest aftershock, a M quake, occurred on October 4, @ am and was located about 3km northwest of the epicenter of the October 1st earthquake.

It killed one person, injured several, and caused additional property damage in Alhambra, Los Angeles, Pico Rivera, and Whittier.

Buildings damaged by the Whittier Narrows, California, earthquake of 1 October were concentrated in several areas, most of which were located 8 to 10 km from the epicenter (corresponding to the critical incidence for SV waves) and were near topographic irregularities, such as the northern part of Whittier, just south of Puente Hills.

Relocated aftershocks (red dots) delineated a north-dipping plane, and seismic reflection surveys (colored contours) showed that this fault extends toward.

Strong motion is ground motion of sufficient amplitude and duration to be potentially damaging to a building or other structure. This turn-of-the-century wooden residence in Los Gatos sustained major damage when it moved off its foundation during the Octo.
