Tongan Aftershock Arrives

After the M7.9 Tongan Earthquake earlier this month, I commented that there would likely be an aftershock between magnitude 6.5 and 6.9 in the first weeks after the initial earthquake. Looks like it just happened. Of course, I'm not claiming any special powers, just using what seismologists know about typical aftershock distributions.

UPDATE: The magnitude of this aftershock has been revised from 6.7 to 5.9. That's rather a larger change than is usual with this sort of reevaluation, so, oops, what I thought was a safe assumption has turned out wrong. The lack of a major aftershock above 6.5 is still somewhat anomalous, so I'll have to guess that there is still one in the works maybe a few months down the road.
