the earthquake last night? There were actually two of them, a magnitude 3.5 quake, centered two miles north of Inglewood, and that one followed a 2.5 magnitude quake a few hours earlier near Baldwin Hills. The shaking rattled some homes and some nerves. Twitter and Facebook feeds lit up, with some of folks asking if the quake was a result of hydraulic fracturing, or “fracking,” which uses high-pressure water to drill for natural gas and oil.
KCRW’s Steve Chiotakis spoke to Dr. Lucy Jones, a U.S. Geological Survey seismologist based at Caltech, about the causes of earthquakes and the city’s preparedness for them – and who should pay to get buildings retrofitted for quakes.
