Earthquake!

Although perhaps tremor would be more appropriate. I was just lying down for a nap this afternoon when there were about three "trembles" as though someone heavy was running up the stairs, but without the noise. Then there was a stronger, longer one that rattled the pictures (and the bed). It was like a helicopter flying low, or someone using heavy machinery on the house - all without the expected noise level. I thought it might be dad, who was downstairs, but he hadn't done anything (or felt anything). Then my brother range from the other side of town - he'd felt it too. I think we felt it because we were a story up in a wooden house - more movement. Lots of people felt nothing if they were in solid buildings like shopping centres. It turned out to be south east of us & measured 5.4 on the richter scale. I haven't heard of any damage anywhere yet.
