Pictures fell from the walls but not too much damage, later noticed cracks in the foundation and walls.
I was in the upper deck at Candlestick Park waiting for the start of the World Series. The rattling began, then the shaking. The stadium got dead silent. At first I thought, "Is that an earthquake??!!" It didn't seem to last very long. When it ended, the crowd (60,000+ people) cheered like crazy!
The stadium power went out, so they couldn't use the PA. A police car drove on to the field and they announced through the bull-horn that the game had been cancelled.
Driving home was an ordeal! When we got to our house, the front door was open but the dead bolt lock was still in the locked position. The house had twisted so much that the dead bolt throw actually cleared the jam!! That freaked me out! :eek:
Thanks everyone, for your replies and discussion! I have to admit, I don't know too much about the technical stuff, I reeeally want to get into geology/seismology as a "side thing". I'm actually considering taking a few geology classes here and there along with my Econ classes at UC Merced when I attend next year (I hope). I go to the USGS site and pretty much get lost in the technical talk, but I think I'm slowly grasping some things.
I think what intrigues me the most are the stories and experiences that people have, and just the awesome energy that is released during an earthquake. To see pictures of liquifaction, cracks opening up, fencelines and roads getting misaligned....it's just so....what did someone say...neat. I mean the tragedies associated with them, failing buildings, rubble, is heartbreaking and scary, but in the end, it's soooo interesting. Being interested in economics as well, it's equally interesting to me, and sad too, that the poorer countries are the hardest hit when earthquakes occur, even in smaller ones. And then to see the earthquake engineering tested and failed, as in the Cypress structure and the Bay Bridge collapses....and the millions of dollars spent to keep buildings standing....when whole cities in the mideast are totally wiped out, everything is rubble. The differences here, the irony of it all, are enormous.
When I was a kid, I remember there were a series of quakes out of the Mammoth area (if I remember right), which I felt and I think got me interested. I felt a smaller one (5.9 or something like that) really well one morning, I was up early doing homework for school, and I heard my house creaking. I thought it was reeeally cool, felt it from jerk to last wave, until I realized that I was sitting directly under the spot where the A/C unit was on the roof. :eek: And even then I laughed (but still got up from my chair). I was so excited I ran to tell the news to my hubby...but for some reason, he didn't like being waken up at 5am to hear that there was an earthquake that he didn't feel. Can't imagine why.... :p But, darn it, I've never been in the middle of a really big one rocking and rolling. Friends have -- I work with a Giants fan, who was also at Candlestick that day, AG. Her accounts are the same, only someone near her had a portable t.v. and so they gathered around that to see the bridges out, reports, etc. pretty much right after it happened, as soon as the cameras came back on.
Me, I was getting ready for work during the Loma Prieta, and since we don't feel the Bay Area quakes very strongly here, I didn't even notice the movement. What DID clue me to what was going on was a glass windchime that I had hanging in my room (mom's house), which was right next to the bathroom. Being the end of summer, I didn't really think about the chiming, until I DID think about it. The narrative went something like this: "hmmm...the chiming sounds pretty...breezy today....wait a minute! My window is not open - therefore, there is no breeze...oh man! Earthquake!! Whoa!!...- then - ....Dangit! I missed the whole thing!" I was actually sooooo mad I missed it. Then the t.v. came back on and I was late for work because I couldn't take my eyes off the coverage. Wow....truly amazing. Felt a few of the stronger aftershocks.
I found the page I posted interesting regarding the types of soil and rock there, and the structures that were built on them, more specifically, the Cypress structure pointed out on one of them. There's also a probability map, in real time. It's updated after every quake, and shows where the next earthquakes are most likely to strike within the next day or so. It's on the same site, basically, but here's the link to the page: 24-hr forecast map If you see red in your area, looks as if you may be in for a ride...
Neat stuff. :D
Very cool link, Z....We use Arcview at the City for most of our mapping and parcel data, and use it ALOT for sending out public hearing notices to property owners. We have older versions of ArcExplorer on our desktops, but due to licensing restrictions, Arcview is on only two computers in the department. So, I end up using ArcExplorer in most of my day-to-day stuff. Handy for answering citizen inquiries, since we have the aerial photos on there, too, and for projects, finding utility easements, hydrants, etc.Quote:
