Glittering Eye and Tsunami

Clusters?

It's interesting to note that, until this quake, the 4 strongest quakes since 1900 happened during a 12-year span, including twice in Alaska. This quake ties for #4. (CNN)

Should we expect a sort of "sunspot season" of seismic activity over the coming dozen years or so?

The Indian Ocean quake was all the more destructive for occurring off shore 100 miles, making a rift (I forget) hundreds (or thousands?) of miles long. In the US Pacific Northwest, there is a rich history of tsunami, including some truly great devastations of the Seattle area.

In the face of all of our arrogance, mother nature humbles us all.

Quakes

Well, actually the Richter is logarithmic as explained by the Canadians here.

The energy released by a 9-point is about equal to all the energy used on the earth by humans for one year according to one source.

There has been a cluster of quakes in the Indian Ocean since the one that set off the tsunami. The USGS has a list here. In some ways it's like Mother Nature adjusting her back: the tension and the pressure move along a fault to the next place where they get stuck until there's a quake.

A friend of mine was killed when the Cypress structure in Oakland "pancaked."
