I'm surprised they haven't suggested a link to El-Quaeda.
Seriously, if you're interested in knowing the pattern/frequency of quakes, you can visit:
http://earthquake.usgs.gov/recenteqsww/ (sorry if someone's posted this before)
and they will notify you of all quakes, or just magnitude 5 and up. We are notitified of >5 quakes, and I was at my computer the two days they were going off before the Tsunami. It felt quite surreal knowing that this was happening to people somewhere, but I was only getting e-mail notifications.
From an observing point of view, it's interesting to watch the quakes following certian tectonic plates. Small ones happen in waves around different plates.
I think I've drifted off Alushe's point here, but some of you might find this of interest.
