Just when I thought I had seen the last of the Quakes for May up pops another, but this time it fell in an R3 period (see below). It just goes to show you can't rate how big a Quake will be until it happens!
Piers uses a scale of R3-R5 and the last time I said we should just keep to the R4+ from June and now we have an R3 with a M6.7!
If we take a look at R3+ stats for May there have been 9 M6+ and 8 have fallen on the Piers Corbyn R3+ scale. Critics would point out that if we did that, the Month would not have many days that did not fall on a R3+ and I have to agree on this. Having said that the Month of May 2012 was expected to have more Earthquakes then normal, hence the increase in R3 days.
