What Neil deGrasse Tyson is to astrophysics, Lucy Jones
is to seismology.
"The last time there was a large seismic event on the fault that can do us the most harm, the San Andreas, in 1857
, Los Angeles had about 4,000 residents. “We really weren’t worried about keeping a complex social structure in place,” Jones said. But as we get bigger and more complex, we increase our vulnerability."
Jones presented her talk, “Imagine America Without Los Angeles”
to the American Geophysical Union Conference in San Francisco in 2013.
is the 20th anniversary
of the Northridge quake
, we still haven't quite figured out what to do to mitigate the effects of the BIG ONE to come.
Perhaps 1 in 100 buildings in this region would collapse after the Big One. Far more vulnerable is our underground infrastructure of utilities. Municipal water lines were installed as much as a century ago. They are decaying and would break in a quake.
We increasingly rely on the Internet and cellular telephone technology for communication, and there is no guarantee those would be up after a big earthquake — especially, Jones said, because there’s no legal requirement that cell towers be seismically strong.
And one hour after the anniversary of the quake that destroyed my parent's home in Northridge and sent freeways plummeting into chasms and dust clouds billowing up through the unlit sky, we had a tiny jolt
that woke us up at 5:27 a.m. PST this morning. It was shallow at 2 miles deep under Studio City, only 12 miles from the Northridge epicenter.
