San Andreas Fault near Los Angeles |
Today’s 4.4 earthquake
centered at the intersection of Mulholland Drive and the 405 freeway was 900
times weaker than the January 17, 1994 Northridge earthquake,
according to the Los Angeles Times.
I guess we should be
relieved.
The quake, a “light”
one, according to the Southern California Earthquake Data Center, struck at
6:25 AM. Already, YouTube clips of a
number of local television anchors in various states of panic have been posted
and re-posted across social media. Bottom
line, there was little damage and no reported injuries. There have been a half dozen or more
aftershocks, and of course, as every news outlet keeps insisting, this could be
a prequel to a larger quake, but that only happens in five percent of seismic
events.
Every day, I drive the
Sepulveda pass right through the epicenter of today’s quake. There was nothing unusual this morning, an
hour after the event, and traffic was unexceptional. The construction crews that have been camped
out for a thousand years widening the 405 were still there pushing dirt around
and playing in the gigantic sandbox that constitutes the clogged artery of the
roadway also known as the San Diego Freeway.
The problem with today’s
event is that we have not had a measurable quake in southern California in a
while. We have become complacent, lulled
into our doldrums by stable ground and warm weather. So at 6:25 we got a little reminder.
Nothing to fear but
fear itself, to quote a long ago U.S. president. For now.
Most scientists say a larger quake is coming, always on the
horizon. Is fracking making the likelihood
greater? Is there such thing as
earthquake weather? The first answer is
maybe; the second is no. But even
without fracking, Los Angeles is earthquake country, and big ones happen with
regularity, at least over geological time.
Earthquakes prey on
the innate fear humans have of loss of control.
We have no warning of a quake. We
cannot flee to higher ground, or seek cover in a basement. There is no earthquake season. When Northridge hit in ’94, I thought I might
move somewhere out of state to avoid future shifts in tectonics, but I found
that every state has earthquakes, and although I consulted maps published by
the United States Geological Survey, actual earth shaking since then has
confirmed what I found on the maps. The
strongest earthquakes in the country occurred in Missouri in 1811-12 and
registered 7.5 to 8.9 on the Richter scale.
They supposedly rattled plates in the White House, and the shaking was
felt over one million square miles. So
it appears we cannot escape our quivering earth.
Unlike the frightened
news anchors who dive under their desks on live television, we must remain cool
and calm. According to several sources,
more people are killed running out of buildings during quakes than are killed
sheltering in place. So duck and cover,
hold on, and wait for the shaking to stop.
And get used to
it. In Los Angeles, to paraphrase the
philosopher Yogi Berra, an earthquake here is simply “déjà vu all over again.”
