A fault line, long believed to be dormant underneath Los Angeles, could link with others and cause a major magnitude 7.4 quake, according to the findings of a new report.
Until now, the 'Wilmington Fault,' was so deep below the Earth's surface, that it was difficult to study.
However, a new analysis published in Bulletin of the Seismological Society of America shows there is activity along the 12.4 mile fault line under the second most populous city in the US after New York.
Researchers from Harvard, the University of Southern California and the US Geological Survey imputed a 'cluster of clues' into a three-dimensional model that revealed activity not previously detected, reports National Geographic.
A fault line, long believed to be dormant underneath Los Angeles, could link with others and cause a major temblor of a magnitude 7.4, according to the findings of a new report. Scientists worry for vulnerable areas, including the city's ports (above)
The Port of Los Angeles (above) would be vulnerable if the Wilmington Fault joined with others to produce a devastating earthquake in the region
The port of Long Beach (above) also would be at risk if activity along the Wilmington Fault
