Hello Mark,

yes, it is completely that. Thank you to have found for me (great photos !).  It is not easy for me to speak in English.

And, no offence meant, but any one who can claim the first one is an earthquake effect has obviously never experienced one first hand.  I would say yours is probably a 2 o 3 on the R Scale.

Experience here may vary, on the east coast of OZ, we get a quake about every 20 years or so usually in the 6 to 7 range but fortunately of very short duration. Last noticable one was centred in the Newcastle area about 100 miles north of Sydney which badly damaged many building in Newcastle and unfortunately many people died from collapsed buildings.

I have seen 3 in my lifetime, one when I was a kid, one south of Sydney and the Newcastle one that shook this house 100 miles away and they all looked the same, like Faiseur's demo.

Yes, 100 miles away, that sounds about right.  Try living in California, though.  If you do, you had better put velcro under all of your knic-knacs. And the visual effect you experience from the ground, where you lay, because it is impossible to stand is astonishing.  I lived there for a short time and gave up in disgust and moved back east.  I fall down enough on my own without the help of nature!

The one I saw as a kid was at about 5 in the morning, it was like someone was shaking the house violently and when I looked out the window, the trees were shaking as well.

Second one was on my dad's property inland and it also occurred at about 5 am. I wasa sleeping in the back of a bus and though it was someone bouncing the bus except that it weighed about 5 tons. Looked out the back windows and all the trees were shaking violently as well. It was reasonably close to the eipcentre

The most recent was the Newcastle one which could be clearly felt here in Sydney. The peculiarity is that this house has its foundations in wet sand as the area was an old swamp before it was drained about 150 years ago and instead of side to side movement it tended to be a single plane vertical vibration. The old part of the house (130 years old) made this low frequency rumbling noise, the new stuff that I had built at the back buzzed as it is a lot stronger brickwork. Fortunately the whole building moved together and nothing cracked. I had friends who lived on the northern side of Botany Bay who did not even notice it as that area is on a sandstone palteau that isolated it from the movement.

The funny part was my mum came down and burnt my ear for doing something to the house so I had to explain to her that it was an earthquake. It happened about 11 am.
