  Has anyone out there been in an earthquake?  Coming from California (the East Bay) I've been through many small tremblers, but I was out of town when the last major one hit there in the late 1980's.  Then I moved to the Seattle area and was in the 7.0 that hit Seattle around 1994.

  Its errie to feel the ground move under you like a dish of jello.  At first you feel the ground roll, like your in a boat on a rolling sea, and you get a dizzy sensation for an instant.  Then that's followed by a sharp shake, laterally, that shifts the ground back and forth under you.

Are you sure you're not talking about the 6.8 earthquake that happened in the Seatle area on Feb 28, 2001?

I remember it all too well

 I have to admit my memory fails me on the date, it may have been 2001.  As much as I hate to say it but all the years are beginning to run together!

 But I remember where I was, working inside the carbor silo at work.  I just got it to start filling again when I felt the ground rock, I thought "Maybe I should be outside while this thing is filling." and as I stepped through the silo's door I noticed the silo's pad was rocking too.  That's when I realized an earthquake was going on.  Then the ground shook up and back.  I looked up at the silo and deceided that whichever way it was going to fall I'd run the other way.  The silo didn't fall and in the end the only real damaged at our plant were broken supports to an induction coil and the conductor that went to it.

 It seems to me that the local newspapers were trying to write that quake up as a 7.0, but its final magnitude may have been less.

 Esselbach, were you in the area when the Seattle quake hit?

At the time, I remember it being reported as 7.0, and even 7.1, but after time it settled as 6.8.

Here's a website

I was in the area. I just checked my charts, and I was closer than I thought I was. We lived just north of a town called Eatonville, only about 20 miles from the epic center Shocked No wonder we felt it so well Grin

Where in Seattle do you live?

  I live in Federal Way, about 25 miles south of Seattle, but I work at the steel mill in West Seattle.

  One of my big worries that day was that I would come home and find my entertainment center laying face down!  Its alittle top heavy and still is.  But when I got home I found everything o.k.

I've been in a few moderately big quakes when I used to live in California.  Now, I'm in tornado country.  Never seen a tornado, but I seen a few mesocyclones.  Very cool to watch.  You can see them rotate right before your eyes.

I know where that is. I've been through there many, many times Wink

The quake left quite a mess. I remember I was doing my schoolwork in my room and heard the distant rumnble. It got closer and when the house started shaking I realized what was happening. I remember being told that a doorway was a safe place under the support beams, but we lived in a mobile home. I ran to my doorway, watched it shaking so bad, that I decided I wouldn't stay there. I remember running down the hallway which had bookshelves along the walls as books and other items were falling.

I remember hearing on the news that aftershocks were possible so I slept fully clothed, with my shoes on that night. Thankfully there were none, and I hope I never have to experience another earthquake in my life Wink

  What's a "mesocyclone"?  I have to admit I've never heard of that term.  But I hope your not living in a trailer park!  If you and Esselback haven't figured it out yet God doesn't like trailer parks and mobilhomes.

  Now for my tornado story.  Several years ago there were a rash of tornados that blew through "Tornado Ally".  Well, there was this guy that lived in a trailer park in that area and he was deathly affraid of drowning, so much so that he took to wearing a lifevest to bed when he slept.  Anyway, one night, when he was sleeping in his lifevest, a tornado passed through his trailer park, blew the roof off his tailer, sucked him out of it and dropped him into the middle of a lake....lifeveast and all!  What are the odds, huh?

Most people know mesocyclones as wall clouds.  And, nope!  I don't live in a trailer home.  Thanks for asking!   Cheesy

 Nice picture!  I take it then that mesocyclones are cyclones that don't touch the ground.

 I know that this question has been asked before, but is the U.S. the only country that experances tornados?  I would think that the stepps of Russia would also have them but I've never heard of them occuring out side the U.S.

I'm still bitter about this.  The only catastophic event I was ever in - I slept through.  It was a 6.4, if memory serves me right.  Not much I remember about it, for obvious reasons.

Plenty of info on the Web. I found this on Wikipedia but don't fully understand it. http://en.wikipedia.org/wiki/Mesocyclone
Identification

The word mesocyclone is, strictly speaking, only associated with weather radar terminology. This is because the presence of a mesocyclone can only be truly verified by Doppler weather radar. Mesocyclones are most often identified in the right-rear flank of supercell thunderstorms and squall lines, and may be distinguished by a hook echo or gate-to-gate rotation signature on Doppler weather radar.

Visual cues such as a rotating wall cloud or tornado may also hint at the presence of a mesocyclone. This explains why the term has entered into wider usage in connection with rotating features in severe storms.

Tornados (or whirlwinds) can occur anywhere. Some areas are more prone to them than others. I still remember one we had here in the late 1940s. It lifted a double-decker bus right off Shoreham Toll Bridge & deposited it in the river. Fortunately the tide was out & nobody was seriously hurt. Before it disappeared harmlessly out to sea it took the roof off my Grandma's house. I was in the house at the time & was terrified.

PS. It was Jan 1st, 1949, just before my 6th birthday. They got the name of the river wrong. It's the Adur. The Arun is further west. http://www.wsfb.co.uk/diary.html

The reason why doppler radar is used to verify mesocyclones is because doppler can identify rotation.  However, I don't agree with that definition saying doppler is the only true means of identifying a mesocyclone.  If you're looking out and you see that baby rotating right before your eyes, you have visually identified what a doppler radar picks up through echoes.

And it's an awesome sight.  I've seen a few of them.

I used to work graveyard shift during, if memory serves me correct, the 1986 quake in Southern California.  I got home from work, and the earthquake struck.  The house began shaking, my wife was still in our waterbed and due to the shaking, really had a hard time getting off the bed.  We stood under a doorway until it ended.

A co-worker of mine was in the parking lot of my employer at that time.  He said the parking lot rolled just like the waves of the sea.  I wish I saw that.
