Earthquake update

When I got out of my car this afternoon at about 1.30, Max excitedly told me that he had felt an earthquake while sitting in our house. There was a rumble for a few seconds. I felt nothing as I was driving the car and bumps in the road surface would have outweighed tremors from a quake. My neighbour mentioned the same effect at the same time, so Max wasn't pulling a fast one!

I've waited all afternoon for a credible news storey to emerge and the evidence suggests that Coffs Harbour, where we stayed last week, was hit by a magnitude 4.2 quake on the Richter scale ... or possibly c. 80-90 times stronger than the 2.5 magnitude quake reported at Southwest Rocks in yesterday's post. Obviously the many quakes in the Macleay Valley and along the coast are interconnected, but my expectation is that we're safe here some 200 km away from the source of the quake. Armidale sits atop a granite underlay and we don't have the unconsolidated sandy soils that enhance a quake's effects.

I wondered if you felt either of those quakes. I saw people reporting them on Facebook. I didn't think the 2.5 would be that noticeable but the 4.2 I thought might have been. How crazy for Max to have experienced that!
