Thanks a lot !!!

Living in california, I have been in quite a few earthquakes, not sure how many. I would guess, at least 10. The strongest that I felt , happened to be when I was living , at that time in a two story house,and taking a shower. I'm sure I broke a record getting downstairs , with a towel wrapped around my body, and soaking wet, at 8 o'clock in the morning.It didn't do any damage to our house, but very scary. Recently, had a good shake about 2 weeks ago, again no damage.
The scary thing about earthquakes is, there are no warning signs, like you have when you have a rain or snow storm.They are very humbling , makes you realize how small and vulnerable we can be. Hope this helps.
I bet you tie up some nice flies!!! good fishin.
Tell your dad and mom 'hi from californee'.

have a good one

I have been through some small ones, but only up to a 4. The only one of those that I felt was when I was on the tenth floor of a building, and you could feel the sway a bit. It was a little weird, but not pronounced enough to be scary.

I have been in at least one that I remember. I was in high shcool, and I remember the building shaking, and the "fire drill." We all trooped outside, and waited while the building was checked out.

I lived in northern Japan for a year and a half. I think that's the earthquake capitol of the world. So many earthquakes that I quite counting. Like living on Jell-O. All of them small except one that I remember. Thought the barracks was coming down.

Most people think of earthquakes and they immediately think of the West Coast or the Pacific. I have been in at least three minor quakes in the Appalachians. The eastern portion of Kentucky is essentially "hollow" with numerous fault systems. The Pine Mountain Fault ran directly under my hometown. Its directly connected to the New Madrid Fault system that extends south into Tennessee, Mississippi and other parts of the South. When I was younger and working in the mining industry, we were required to set up seismographs (sp?) 24 hrs before a major blast and to had to leave the devices in place for 72 hrs to monitor any platonic activity. None of the quakes did much damage other than a few cracks in old brick and mortar foundations and the occassional broken window or dish. Most of the time, we did know it was an actually quake until it was confirmed by the USGS. Most of the time, we just thought is was a nearby mine or road project. Blasting is a continuous event in a coalfield region.

Thanks you all

Believe it or not, there are several faults here in Arkansas. A 3.3 magnitude earthquake
occurred in the NorthEastern part of the State a week or two ago. I've never actually
been in one, thankfully. Our problem is tornadoes. I've been through two of those. The
last one pretty much leveled the town.

Mini Hub,
Here is a good website for earthquake information http://earthquake.usgs.gov/earthquakes/. Click on the link titled "Learn" on the second row from the top http://earthquake.usgs.gov/learn/kids/. There are several educational links there for all ages. Another interesting site with a map of most recent earthquakes in California http://quake.usgs.gov/recenteqs/latest.htm. The thing about earthquakes is there isn't any warning. BigDaddy and Mike are right about earthquakes happening anywhere too. Some of the biggest quakes happened in Missouri in 1811 and 1812 (The New Madrid Earthquakes). They were considered bigger than the San Francisco earthquake of 1906. My wife is a geologist so I get a lot of information about earthquakes.

Here is a list of some of the bigger earthquakes that I have experienced with some links to more information. I have no idea how many I have actually felt. Most of the earthquakes are small, and like Pat said, there are really too many to list or remember. in fact, Newhall California had one about 7 hours ago of 3.3. It wont even make the news.


Newhall/Sylmar Quake 1971 - magnitude 6.6. First one I remember. It was like a roller coaster ride trying to get down the hallway of our house. http://www.seismo-watch.com/EQSERVICES/Not...anFernando.html

Coalinga Quake 1983 – magnitude 6.7. I was about 25 miles from the epicenter working up near the top of an extension ladder when that one hit. You could hear it coming. The sound came from my left and when I turned and looked you could see a wave coming down this concrete walkway. Got off that ladder pretty fast. http://www.seismo-watch.com/EQSERVICES/Not...2.Coalinga.html

Here's a picture of a damaged building in the town of Coalinga. Where I was at there wasn't nearly as much damage.


San Simeon Quake 2003 – magnitude 6.5. I was about 100 miles from this quake sitting at my desk on the seventh floor of my place of work. There was some sway and it made everything shake and rattle. Felt for the guys on the 22nd floor. It made me nervous. I did have an office in the building pictured below. Moved out years before the quake. It is still a trip to see the building I was working in on the ground.



California - Ah yes, the Golden State, also known as the Shake and Bake State (fires, floods, earthquakes, and drought aplenty), or the Granola State (a bowl full of fruits, nuts, and flakes).

Excellent info, Cencalfly.

Why I'm asking about earthquakes does anyone know how many earthquakes happen in the USA in a year.

[cencalfly]

Hi Mini Hub,

Here is a link to a table on USA earth quakes per year. http://earthquake.usgs.gov/earthquakes/eqa...ts.php#table_us

For 2009 it looks like there was 4227. Remember though, these are just estimates becuase many smaller earthequakes are not recorded or reported. Also, like mentioned earlier other events such as blasting or other earth movements (slides or sink holes/collapses) are not actually earthquakes like those from faults in the earth.

[Mini Hub]

Thank you for the website Cencalfly.

I have only felt 1 while living in North Idaho in the early 80's.

Great info, cencalfly. In southern california, the san andreas fault creates the most interest, it is south of the san berandino mountains and about 50 miles from the pacific ocean. 15 years ago, the state built the diamond valley reservoir for water strorage, in case of the "big one".Diamond valley reservoir is now considered one of the best fresh water fishing spots in this area, and just gets better and better.I was a volunteer docent for 5 years when it was being built. fantastic information to pass on to the public;prehistoric animal finds, wooly mastodons , rare animal finds, indian living sites dating back to possibly 6000 years ago etc. All of this is now covered with water. Diamond valley reservoir is 4 1/2 miles long. 2 miles wide at the widest point, and the deepest point is approx, 250 feet deep when at the maximum amout of water!!!The water comes mainly from the colorado river about 240 miles away, just recently the " inland feeder " was opened to bring water from cental calif. by way of silverwood lake.As you may have guessed , water is extremely valuable to southern calif., so daimond valley is critical for water availability in case of the "big one".San andreas fault and diamond valley reservoir are a couple other spots to check out for earthquake related information.

Have a good one
