Posted this over on Quake Watch 2011 but thought some here might be interested.
As was recently advised the June 13th quake has been upgraded to 6.441, making it bigger than the February quake which caused all the damage and loss
However that alone does not make it the highest release of energy over the 72 hour timespan I use for aftershock series .
The Feb quake and 72 hrs of aftershocks still released the most energy, even more than the 7.1 and 72 hours of aftershocks
It looks like the two 5.8 and 5.9 aftershocks right after the 6.3 in Feb really made a big difference to the energy totals.
Also the graph shows the 7.1 as a slow lumbering giant of an aftershock series, whereas the Port Hils Feb and Taylors Mistake June aftershocks came in
rapidly within hours.
The Pegusus Bay 23rd Dec 6.0 is preliminary at this stage, it could be a month, if not 6-12 months before all the aftershocks are determined, but
there is no doubt whatsoever the numbers shown for that can be doubled .
Good for an overview anyway.
