Part of Southern California life is dealing with the fact that a major earthquake could dramatically alter your life at any moment. It’s been nearly fifteen years since the 6.7 magnitude Northridge quake dropped freeways, toppled buildings and killed 57 people in SoCal. Since then, we hear reports every couple of months that “the big one” is coming or is long over due.
Living in SoCal, you do get the moderate sized quakes on a relatively regular basis. Just last year, on July 29th, we had the Chino Hills earthquake with a magnitude 5.4 that was felt pretty strongly throughout the SoCal area. I was standing in line at a taco stand on my lunch break when that roller shook the nerves of the Los Angeles Basin.
And the most recent quake occurred just last night. Last night at approximately 7:49 p.m. PST, a magnitude 4.5 earthquake jolted through Southern California. According to our Local ABC News station
The earthquake hit at 7:49 p.m. within 1 mile of San Bernardino. A 3.3-magnitude aftershock hit about an hour later, followed by a 1.7 aftershock.
It was felt as far south as San Diego and as far north as Palmdale. People who felt the earthquake described it as a little roll followed by a big jolt.
While I did not feel the aftershocks, I did feel the small jolt of the actual quake. It was rather insignificant and I had to ask my dad whether that was actually a quake or not.
I bring this up because I realize that with my eventual move to New York, I will no longer have to worry about this. Now, while I realize the mega quakes (such as the ‘94 Northridge quake and the ‘89 San Francisco quake that disrupted the World Series) are very disruptive and often times fatal, I sort of enjoy theses little tremblers. It sounds odd, I know, but these little quakes that do no real damage and cause no injury are actually kind of fun. These quakes are a quick rush of adrenaline and excitement.
There are two different kind of earthquake feelings, the rolling or the jolt. During a rolling quake it literally feels like the ground beneath you is rolling like a wave, usually for a period of 3o to 90 seconds. During a jolter, it could actually be pretty frightening. A jolt earthquake, in my experience, could last as long as 2-3 minutes and feels like someone is shaking your house like a salt shaker. Why would this be exiciting? As I just stated, it gives you a bit of an adrenaline rush, and immediately afterwards everyone is talking about it. “Where were you when the earthquake hit?” “How strong did that feel?” “Do you think it’s just a precursor to THE BIG ONE?”
In reality, according to a US Geological Survey Scientist I saw on the local news last night, an earthquake like yesterday’s has a 1 in 19 chance of causing a larger, more significant quake. Yesterday’s earthquake, in particular, had all the earthquake “experts” on the news channels because it was on a fault line that bordered the ever dangerous San Andreas Fault, which is one of the largest and most active in the world. The San Andreas Fault is projected to be the fault line that will produce the ever so worrisome “Big One.” While my belief in the fact that Southern California will break off and slip into the ocean from The Big One is a bit tempered, it still worries some people in this area.
I guess what I’m saying is that last night, while enjoying a relaxing beer after a hard day’s work, I got a nice little jolt of adrenaline. I wonder what sort of natural disasters I’ll have to worry about in New York?…
