Have you ever been in a earthquake?

We experienced an earthquake in Mallaig last summer. Heard a very loud bang but felt nothing, then read the news a little while later and learned that an earthquake had affected the West of Scotland at the time in question. All a bit underwhelming.
 
I was watching Japanese telly the other day while convalescing and was interested in a programme about a company that makes enormous coil springs to individual orders. The big ones are used to support buildings as part of the damping systems, such as those that you will be relying on. An interesting feature of the firm was that all the staff, including salesmen, have to make at least ten springs per year.

Interesting, ones I saw didn't appear to have springs and looked like giant hydraulic cylinders, similar to car "shocks" on a huge scale. I assumed hydraulic damping but they could have had internal springs. My friends had moved a few times over the last 20 years as newer buildings were much safer than the older ones. It is very disconcerting when the earth moves in the middle of the night, at least my wife thought so :D:D.

I've had a bad case of benign paroxysmal positional vertigo and that's way worse than a mild earthquake. No chance of even managing to stand up when that hits.

Two. both in UK and both in the mid 80s with epicentres in N wales: First one we felt in Birmingham was as othes have said like a big lorry passing by, except it was much lower fewquency and was enough to set ano openm door moving and the curtains swinging. Only realised it was a quake, when the local news mentioned it later. The other we were at anchor in Porth Dinllaen and heard a long rumble, a bit like an avalanche of stone. Again we only found out what it was when we ashore later for a drink at the local, and found them all talking about it. As the boat was rolling a bit anyway, we never noticed any unusual movement.
 
Yes, inbound up Seno Aysen towards Chacabuco on April 21st, 2007. Although in several hundred metres of water it felt as if we were going over a shingle bank. Happened again a few minutes later which was when I noticed , about 3 miles ahead, a big cloud of dust coming out from behind a headland on the northern shore, it was black and red. It was preceded by a very high breaking sea standing proud above the horizon.

Shortly thereafter the sea became very unsettled and remained that way until we reached Chacabuco where there was some minor damage in the port.

Despite happening in a very remote location all 13 people employed on salmon farms along the south shore died.

What caused the destruction was that the terremoto caused the side of a mountain to fall into the sea and sent a - for want of a better word - tsunami across the seno. This sank several salmonera barges and stripped trees which had previously extended right to the water's edge from the shore. It then 'bounced' back across the seno and ran up and over any low lying land there.

Upon checking in at Chacabuco the Port Captain advised us to leave as soon as we could, navigating only in daylight on account of the number of deadheads in the water, as they had experienced several hundred terremotos in the previous month and were still waiting for the big one.

Lots. Something around an R3-4 in South Cheshire , possibly the same as one of the ones experienced by colind3782 in post 4 in neighbouring Shropshire.

Two in Zakinthos

One in a cave in the Friuli region of North Itlay, an aftershock following a serious earthquake in the region around Udine
 
Yes, Northridge, 1994, I think it was 6.7.

I was in a high rise hotel, with a glass bar structure on the floor above! Carnage.

Could see wires sparking and gas explosions from the hotel windows. The traffic lights were rocking all over the place.

I was able to drive around afterwards and look at the damage and the roads that had fallen down!

There was a parking structure that had fallen like a house of cards!

One of the freeway bridges fell and a section of freeway collapsed.

The aftershocks were most worrying, and people became more nervous as days went on.

Not an experience to be repeated.

There’s constant earthquake activity in Turkey http://www.koeri.boun.edu.tr/scripts/lasteq.asp and on average we would experience 3 or 4 per year which would rattle the house. We had 2 big ones in the last year which really shook the place. One was a 6.6 in Bodrum and the other a 6.3 north of Izmir. Both were followed by hundreds of aftershocks many of which we would have have felt.

We arrived in Yalikavak (Bodrum), just after the big one and stayed for a month so experienced not far off one hundred after shocks.
Was in a 6.? in Tbilisi in the late 1990s
 
They don't call NZ the shaky isles for nothing so i had experienced many earthquakes including some quite big ones that were a long way away.
None of this prepared me for the experience of being in Christchurch in feb 2011 when the earthquake struck and killed 186 people and decimated the CBD.
The level of violence was astonishing and terrifying on a primal level.

The damage was so great because it was essentially right under the city. I likened it to standing on a jack hammer and later the peak ground acceleration was published as being 2 g ie 2 times the force of gravity! with a large vertical component.
Very very scary...
 
Yes - this one

We were camping overnight on a climb of Mount Ischinca. The really odd thing was that when arrived arrived at the camp I asked if they have many earth quakes as there were hundreds of sizeable holders lying around to be told no hardly ever. I nethertheless placed our tent well away from these. That night the ground turned to jelly for 2 -3 minutes, a most bizarre feeling! If only my intuition would enable me to do something useful like win the lottery!
 
Our first was when we were in rented accomadation, in Chaguaramas Trinidad, as our boat was having it's teak decks removed and and repainted. The building shook and we went into the loo on the basis it had the smallest ceiling. Our second was in, Rodney Bay Marina St Lucia, again everthing shook and the mooring post in front of the pontoon was moving side to side. The disaster was all the spirits and wine bottles were knocked off the shelf of the local off licence shop and smashed. I did offer to lick the floor dry but was told there would be too much glass. Both were 3s on a scale of 8.

Yes
22 floor of Hotel in Tokyo category 7 in Tokyo Bay . Building swayed making groaning sounds . woke me up . Thought it was sumo wrestler having fun in room next door . Curtains swayed
 
Lots of activity here yesterday evening and last night.

? numbers don't make sense (to what I know and understand). Care to elaborate?
I mean if there was a 9.5 or 10.7 richter (sp?) scale, I'd have known as there would probably be a tsunami washing off the whole of Greece and half of Turkey...

Sorry you're right a bit more information would have been appropriate. The 9.5 and 10.7 refer to the depth and the corresponding Richter readings for those two were 2.0 and 2.6 and you'll see we had a 3.1 and 3.5 at the shallower depths of 5.8 and 5.0 Km respectively.
