I grew up in Perth, Western Australia, where tremors are fairly common, and remember what is know as the Mekering earthquake because it flattened the small town of mekering. That was a 6.5. When I felt Sunday night's I said to my husband "That was pretty big for here, must have been about 5" I was really impressed when I found out how close I was! Who needs seismologists! I don't think it feels like a lorry going past t all. The first bit, which woke me, felt as though the house had jumped sideways.
