NEW YORK, Oct. 10 (Xinhua) -- The ground beneath U.S. Southern California has been particularly unsteady as of late, with the region experiencing more moderate-sized earthquakes this year than it has in decades, reported the Los Angeles Times on Thursday.
"What precisely is fueling the sequence of shakers is not entirely clear, and officials warn that prior seismic activity does not necessarily mean more powerful temblors are imminent. But the series of modest shakers have many wondering what is going on," said the report.
