I've never posted to a blog on blogs.com before, seems like a nice format.

I was impressed by the same top three as you - Campillo's noise cross-correlation, Romanowicz's hum, and Kanamori and Allen's rapid source magnitude estimation.

I bookmarked this - do you know of other seismology blogs?

Blogs.com is actually TypePad -- the same software as Moveable Type, but they provide the hosting (you can chose blogs.com or typepad.com domains). There's no free version, unlike LiveJournal, but I like the clean design -- I'm a bit of a sucker for nice layout and typography. One of these days I'll splurge and buy the full set of Edward Tufte's books.

It's funny how AGU works that way -- a huge meeting, but there's always a buzz that tells you what's big, even if you don't hear it yourself. I actually missed hearing the Kanamori/Allen result first-hand, but I heard something about it, and then I had the good fortune to sit next to Richard Allen on the flight back, and heard the rest. It's a marvellously counter-intuitive result.

As for other seismology blogs -- I haven't found any yet, though I haven't done any extensive digging beyond a little preliminary google work. If I find anything, I'll let you know, and it'll probably end up in the sidebar on the left.

Regarding the Allen/Kanamori work - I think it is a bit over-hyped. I'm sure it is useful, but it probably amounts to being able to tell a big earthquake is happening by the time it is a quarter to a half over. Certainly, many huge earthquakes remain relatively small for more than 10 s, and it probably is impossible to tell whether they will continue to grow ahead of time. There is only a weak correlation between the initial time functions and the eventual moment for large datasets. I could be wrong, though.

The format is easy on the eyes. I think I prefer LiveJournal, mainly because the students at UCLA show up more there than here. They are even more underfoot on Xanga and FaceBook, but those seem superficial and gaudy. LJ also has various levels of privacy for posts, although I don't use them much.

I'll have to remember to check here from time to time.

A friend of mine actually set up an RSS feed of this page on LiveJournal, which might be useful: http://www.livejournal.com/users/seismology_log/

Added the link to my LJ friends list. Good idea.


ORANJESTAD, Aruba - Felix rapidly strengthened into a dangerous Category 5 hurricane and churned through the Caribbean Sea on a path toward Central America, where forecasters said it could make landfall as “potentially catastrophic” storm.
Felix was packing winds of up to 165 mph as it headed west, according to the U.S. National Hurricane Center. It was projected to skirt Honduras’ coastline on Tuesday before slamming into Belize on Wednesday.
“As it stands, we’re still thinking that it will be a potentially catastrophic system in the early portions of this week, Tuesday evening, possibly affecting Honduras and then toward the coast of Belize,” said Dave Roberts, a hurricane specialist at the center in Miami.
