Years ago when we had a tremor in Newcastle(a while after the biggie), I contacted local authorities
They said that it wasnt a tremor as it didnt register on their seismograph equipment, nor in Canberra.
The fact was that people in neighbouring subburbs also heard & felt the rolling rumble, as the wave moved from NW to SE. I was ironing at the time, my board shook first, iron fell over, and things went"rocky" underfoot. A split second later, I heard the crockery rattling together at the other end(SW) on my house. Whole thing only lasted just over a second. I have cracks in my celing, and broken floor tiles on the laundry to prove it.Just a small compared to the trauma we went though in the Big Newcastle Quake... but now I am experienced in what a quake tremor feels like.. it is unmistakable.
I figure that their equipment wasnt working.
