Reply - U. S. Geological Survey

I received a reply today.


Click here to read my original letter to the U. S. Geological Survey from October 22, 2010.


The reply:




Excellent reply back from Michael Blanpied there... as he mentioned, I did neglect to include the printout of the maps I posted on my initial post. I realized this as soon as I dropped the letter in the mailbox. I left it laying facedown on my desk, but opted to not send out a second letter. I figured he knew what I was talking about, and sure enough he did.

I wasn't aware that all earthquakes start out the same... that supports the idea that it's pretty much impossible to predict the magnitude of a quake. He does say there are early warning systems in place in a few locations, although it sounds like California has yet to secure the financial backing to deploy one here.

Basically, Michael gave me some great resources to work with. Click here for a copy of the article from the journal Seismological Research Letters that he included.

The office building where I work, my office is not on the ground floor. I don't have easy access to the outside, either. There are large metal beams holding this structure up, and nails sticking out of the underside of the floorboards all over the place. I've been in this building when an earthquake has hit, and it was unnerving to say the least. My boss, an older gentlemen of small stature that doesn't move very quickly at all, hurdled over his desk and sprinted out of his office door, and down the stairs with lightning speed. I was pretty much right behind him, and all I could imagine was the beams collapsing, the staircase crushing us, and it all being finalized as the floorboards from upstairs came crashing down, nails piercing our twitching bodies.

Ungh. I think about this every time I go into and out of work.

Very informative reply. Thanks, USGS!

Dear U. S. Geological Survey

Dear U. S. Geological Survey,

I am writing you today to ask your opinion on something. Within the past year, I've started to find myself becoming acutely paranoid about earthquake strikes. I was born and raised in Southern California so you think I'd be able to shrug this sort of thing off, but for whatever reason I find myself checking the USGS Southern California Fault Map on an almost constant basis... not that it's supposed to give me a heads-up or anything, but I like to think that maybe I'll spot a pattern or trend that I can use to my advantage.

San Diego, California is my home. While I can't recall ever having been hit with too major of an earthquake, I've got to say that the location of some of these fault lines have me a bit concerned. Please review the enclosed printout that I've sent with this letter.



Do you see this? Those squares of death are getting closer and closer to swallowing up my city. I remember back in April, I was at home drinking some traditional Easter beers on a Sunday when a rather big quake hit. At first, I thought it was a product of the buzz I had going on, but then I noticed my TV was about to fall over. I had to jump up and brace it while waiting for the shaking to die out. Actually, it was more of a rolling... like ocean waves.

Ever since then, I've felt on numerous occasions that we were experiencing an earthquake. Half the time, it's all in my head. I don't know why this happens. I think I'm experiencing psychological trauma.

What I'm wondering is... how are you guys and gals at predicting these things? Is there a time in the future when you think you'll be able to calculate when and where a quake will hit with any reliable bit of probability? How safe do you think San Diego is at the moment? And how much longer do you think I'll have to deal with these faux earthquakes that I think I experience?

Thank you for what your teams do. It's good work, and interesting to read.

Be safe,

Daniel
