The Northridge earthquake caused high shaking intensities for several million persons in the northern Los Angeles region, centered in the San Fernando Valley. Fire protection for the heavily damaged area is furnished primarily by Los Angeles City Fire Department and, to a lesser extent, Los Angeles County, Santa Monica, and other departments. The earthquake resulted in about 110 fires, about 80% of which were structure fires. Of these, most were in single-or multi-family dwellings. All of the initial fires were out before noon despite impaired communications, wide-scale failure of firefighting water supply in large parts of the San Fernando Valley, and other problems. Alternative water supplies, such as backyard swimming pools, were employed in some cases. Mutual aid was requested by fire departments in the affected area, but resources from outside the Los Angeles metropolitan area were not required.

The Moment

The Northridge earthquake occurred on January 17, 1994, at 4:31 a.m. Pacific Standard Time. The hypocenter was about 32 km west-northwest of Los Angeles in the San Fernando Valley at a relatively deep focal depth of 19 km. The moment magnitude for the earthquake is Mw6.7. The earthquake occurred on a south-southwest dipping thrust ramp beneath the San Fernando Valley and, thus, reemphasized the seismic hazard of concealed faults in the greater Los Angeles region. The Northridge earthquake also indicates a continuing high rate of seismicity along the northern edge of the Los Angeles basin.

Suburbs have long been glossed over by critical urbanists for being culturally, even if not spatially, less than urban. In Los Angeles, it is the San Fernando Valley that has received such treatment as scholars have tended toward the metropolitan basin. In this article, I aim to help re-center the San Fernando Valley as a complex and conflictual cultural landscape through an autoethnographic exploration of four moments of urban restructuring in the Panorama City neighborhood. I provide a personal account of how a succession of events – the 1992 LA Riot, 1993 General Motors Plant closure, 1994 Northridge earthquake, and 1996 dismantling of the Aid for Families with Dependent Children welfare program – led to the disruption and partial destruction of a neighborhood. I situate these moments of crisis within the context of a civil gang injunction and outbreak of abject violence during this time period, which further destabilized the neighborhood and informed my own decision to pick up a gun.

Interpretation of significant ground-response and structure strong motions recorded during the 1994 Northridge earthquake

The Moment

Abstract Some of the largest accelerations and velocities ever recorded at ground-response and structural sites occurred during the Northridge earthquake. These motions are greater than most existing attenuation models would have predicted. Although the motions are large, the correspondence between measured acceleration and damage requires further study, since some sites with high acceleration experienced only moderate damage. Also, some peak vertical accelerations were larger than the horizontal, but in general, they are smaller and fit the pattern observed in previous earthquakes. Strong-motion records processed to date show significant differences in acceleration and velocity waveforms and amplitudes across the San Fernando Valley. Analysis of processed data from several buildings in the San Fernando Valley indicates that short-period buildings such as shear-wall buildings experienced large forces and relatively low inter-story drift during the Northridge earthquake. However, long-period (1 to 5 sec) steel or concrete moment-frame buildings experienced large inter-story drift. For this earthquake, accelerations did not always amplify from base to roof for flexible structures like the moment-frame buildings, but the displacements were always larger at the roof. The drifts at many of the moment-frame buildings were larger than the drift limit for working stress design in the building code. The records from a base-isolated building indicate that high-frequency motion was reduced significantly by the isolators. The isolators deformed about 3.5 cm, which is much less than the design displacement. The records from a parking structure show important features of the seismic response of this class of structure.

Water Politics and the San Fernando Valley: The Role of Water Rights in the 1915 Annexation and 1996-2002 Secession Campaigns

Municipal water rights played the central role in the 1913-1915 campaign to annex San Fernando Valley communities to the city of Los Angeles. Jordan Scavo explores why the water issue was downplayed by both sides in the 1996-2002 Valley secession campaign. He finds that the water rights debates are a measure of the extent to which the Valley and the city have become bound to each other.

An earthquake struck the San Fernando Valley on January 17 at 4:30 am. Pacific Standard Time. The epicenter was located at 34°13' North, 118°3' West at a depth of 14.6km. The surface wave magnitude from the National Earthquake Information Centre was 6.6. The local magnitude was 6.4. Most of this information was prepared within a few days of the earthquake occurring and some of the material included in this report was issued as a press release. A more detailed report is currently being prepared by the Reconnaissance Team sent by the Society.

Race And Place

We provide an example of how race- and place-based legacies of disinvestment initiated by New Deal Era redlining regimes under the auspices of the Home Owners’ Loan Corporation (HOLC) were followed by decades of anti-gang over-policing tactics at the scale of the neighbourhood. We show how HOLC-mediated and mapped redlining has sustained community disinvestment and stigmatisation wrought by unjust and racist social policy seen to this day in contemporary geographies of gang abatement in the form of mapped gang injunction ‘safety zones’. As we illustrate with the use of two case studies from Los Angeles – in South-Central LA and LA’s San Fernando Valley – it is overwhelmingly redlined neighbourhoods that have remained marginalised, becoming civilly enjoined ‘gang’ neighbourhoods faced with oppressive anti-gang policing tactics over the past few decades.
