A few minutes ago, a 4.7 aftershock shook parts of Christchurch and was felt as far away as Timaru and Dunedin.
The tremor was centred 11km deep near Rolleston and was felt as quite a strong rocking motion and continued for several seconds.
Twenty minutes earlier a 4.0 magnitude shake struck near Lyttleton.

Today is the 31, 3 and 1 equals 4, so a good shake was on the cards here today if you use the “4 Scenario”
I think I may beat Ken Ring on my earthquake predictions with the 4 method?

I really wish the media would stop going into hysteria mode with every moderate aftershock that wobbles us. 5.0 and over by all means is a decent shake, but these ones today were nothing to write home about, just more of the same of what we have pretty much every week.
For Stuff.co.nz to sensationalise the situation with the headline “Large aftershocks hit ChCh” is just lazy and very poor journalism.

Well it really does depend on the distance of the epicentre. Generally it needs to be around a 5 to really get the nerves frayed. However anything above 4.6 or so on the port hills fault feels like a 5 from the greendale. In fact 2 weeks ago we had a 3.9 in HoonHay just 700m from the house and it felt like a 5. Just shows what a little distance does. Have been teaching at Hornby High School today and didnt feel the 4,0. Felt the 4.7 though, heard it coming and gave the gym there a little shake. Was walking about in a PE class anyhow so would have felt stronger sitting down at home. Anyhow, – distance is key!
