A look back at the damage, deaths and developments in seismic safety since the disaster:. At a. The so-called blind thrust fault — one with no surface features to reveal its presence — caused a block of earth to move upward. Most of the energy was released toward mountains that line the northern side of the valley, but there was more than enough energy sent in other directions to cause devastation.
It was felt as far away as Las Vegas. The state said at least 57 died in the earthquake, though a study issued the following year put the death toll at 72, including heart attacks. About 9, were injured. The greatest concentration of deaths occurred at the Northridge Meadows, a unit apartment complex where 16 people were killed when it collapsed onto the parking area below, crushing first-floor apartments.
The widespread damage to buildings, freeways and infrastructure made the Northridge quake the costliest U. Systems of concealed faults under the Los Angeles area are more complex than previously thought. The significant fracturing of welds in steel frame buildings was unexpected because of the ductility of steel. Understanding the cause and correcting the problem will be essential to continue building in earthquake prone regions. Damage in Santa Monica The hospital in Santa Monica shows classic "X"-pattern cracks as evidence of the damage it sustained during the Northridge earthquake.
CSUN Parking Structure Damage This car-capacity parking structure, a recent addition to the Cal State University - Northridge campus, suffered partial collapse in the intense shaking of the Northridge earthquake. A close-up of of this entrance to the parking structure shows the closely spaced fractures in the reinforced concrete columns which allowed "bending" of the outer wall. San Fernando Valley Apartment Damage The apartment house on the left has collapsed onto the former garage level.
The apartment house on the right, a twin to the collapsed structure, did not fail. This buckling shows the structural failure produced by high vertical acceleration. Health Clinic Damage This picture shows the exterior paneling from the former second floor hanging down across the top of the first floor.
