    The Sierra Madre earthquake occurred on June 28 at local time with a moment magnitude of and a maximum Mercalli intensity of VII (Very strong).The thrust earthquake resulted in two deaths, around injuries, and damage estimated at $–40 million. The event occurred beneath the San Gabriel Mountains on the Clamshell–Sawpit Fault, which is a part of the Sierra Madre Local date: 28 June For example, the Landers Earthquake (M ) in the Mojave Desert was a big hazard but did not represent a big risk because of the low population of the affected area. On the other hand, the Whittier Narrows Earthquake (M ) was a much smaller hazard but a larger risk because it struck in the middle of Los Angeles.

    The Loma Prieta earthquake of Octo , again proved the reliability of hinge and joint restrainers, but the tragic loss of life at the Cypress Street Viaduct on I in Oakland emphasized the necessity to immediately accelerate the column-retrofit phase of the seismic-retrofit program for bridges with a higher funding level for both.   On October 1, , the Magnitude Whittier Narrows earthquake shook the Los Angeles area, causing significant shear damage to the I/I-5 Separation. Based on PEQIT’s investigation, Caltrans began developing contract plans to retrofit bridges with single-column bents (a substructure unit supporting each end of a bridge span).

    The Rapid Raw Strong Motion (RRSM) is an entirely automated system that uses open data from EIDA. It provides earthquake information and strong motion parameters including PGA and PGV within minutes of any event. The Engineering Strong-Motion database (ESM) is a reviewed archive of accelerometric waveforms from events with magnitudes above The earthquake was centered at Whittier Narrows, Southern California, on October 1, , with M = (BKS), M = × 10 25 dyne-cm (BKS). The array, called the Strong Motion Array Taiwan-One (SMART 1), was installed in northeast Taiwan, which is currently much .

In particular, the Whittier Narrows (October ), Sierra Madre (June ), Northridge (January ) and Chino Hills (July ) earthquakes were considered in the studies reported here.

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.

The October 1,Whittier Narrows earthquake (ML=) ws located at 34°'N, °'W, at a depth of +/ km in the northeastern Los Angeles basin. Acceleration response records obtained during the October 1, Whittier‐Narrows earthquake (M s = ) from the 32‐story, vertically irregular Wilshire Finance Building, of which the cross section changes from a nominally rectangular shape to a triangular one, are analyzed.

The building was instrumented with 21 channels of synchronized sensors, consisting of 12 uniaxial. Strong motion is ground motion of sufficient amplitude and duration to be potentially damaging to a building or other structure.

In earlythe San Fernando Valley was the scene of a dense network of strong-motion seismometers, which provided a total of seismograms. This made the earthquake the most documented event, at the time, in terms of strong-motion seismology; by comparison, the Alaska earthquake did not provide any strong motion affected: Greater Los Angeles Area.
