Yes, I talked to Alvaro via IM about 2 hours ago. He was already
online. His apartment building was shaken up but undamaged and his
family is fine too.

Is there a higher then normal amount of earthquakes happening recently?
haiti, japan just had one for 6.9, there was apparently one in illinos a
few weeks back, one on the Russia/China/N.Korean border and now Chile?

Hi. We're out of town right now, and it seems I can't get to my home
machine (probably just a loose cable). Our building was shaken badly
enough that we'll have a lot of work to do to make it usable again.
Our earthquake was 8.3 or 8.8 depending on who you ask, and whatever
it really was, it was strong enough to tear down a bunch of
buildings. Not on my zone though, fortunately for us. I have
several friends on the worst area though :-(
(I have to note that buildings here are built to resist this kind of
thing, so the fact that some went down means that it was really
strong)
Re: the more frequent earthquakes, yeah I was thinking the same
today. An actual scientific study would be more useful than idle
speculation though ...

Glad to hear you were in a safer zone .. something I've never had to
weather so far in my life, and would rather keep it that way ;(

One comment that one guy at work had about this was along the lines of
aftershocks, where there is a ripple effect that radiates out from a big
one affecting seemingly unrelated areas ... not sure how much I subscribe
to that theory, as one would think that the 'aftershocks' would be less
intense then the original, and, so far, 8.3/8.8 sounds *alot* higher then
anything I've heard of recently ...
My thoughts and prays go out to you and your family ...

I find these links useful:
http://earthquake.usgs.gov/earthquakes/eqinthenews/2010/
http://earthquake.usgs.gov/earthquakes/eqinthenews/2009/ ...
I note
an 8.1 in Samoa in Sep 2009
no 8.x's in 2008
an 8.5 in Sumatra Sep 12 2007
an 8.0 in Peru, Aug 2007
an 8.1 in Solomon Islands Apr 2007
an 8.1 in Kuril Islands Jan 13 2007
an 8.3 in Kuril Islands Nov 2006
an 8.7 in Sumatra, March 2005
an 8.1 in Macquarie Island Dec 2004
an 8.3 in Hokkaido Japan, Sep 2003
So yeah, if we're counting 8.8+'s this year's worse than usual;
but 2005's 8.7's close.
But if we're counting anything over 8.0, 2007's up there as well.

Random events come in bunches - something I always stop to remind myself
of whenever there is a sudden bunch of quakes, celebrity deaths, plane
crashes, etc. Especially with relatively unusual events like
great-quakes and plane crashes, it can be tough to see if there is any
signal in the noise - a job I have to leave to experienced statisticians.
The world averages one "great" (8+) earthquake/year which, of course,
means some years like 2008 have none but 2007 had four. 7-7.9 like Haiti
or our own Loma Prieta quake are far more common averaging ~17/year.
Haiti is a catastrophe not because the quake was of unusual size (it
barely made it into the 7-7.9 category and released less that 1/15 the
energy of the Chile quake) but because the hypocenter was both shallow
and fairly close to Port-au-Prince combined with terrible construction
standards and virtually non-existent emergency-response capabilities in
Haiti.
Some general quake stats/facts are here:

I'll nit pick a little bit...
Random events are often *noticed* when there is some reason to think
it's an unusually large batch.
Nobody really notices the carnage on the highways, because,
stochastically, there are such a large number of events, both positive
and negative (e.g. - millions of people making it home safely, and a
tiny number that don't) that it's difficult for there to be a
sufficiently large number of "adverse events" to notice.
People are a lot more worried about terrorists than about car accidents,
even though the latter are *enormously* more likely to cause one's
demise, by a *huge* factor. (This mismeasurement irritates me a lot,
particularly when I visit airports!)
2010 has had more news about earthquakes than other nearby years, but as
you say, it is not obvious that there is any signal to be found in the
noise.
<http://en.wikipedia.org/wiki/List_of_deadly_earthquakes_since_1900> is
an interesting list. Very few quakes are listed for 2009; I wonder if
this results from events not being reported yet? Preceding years
consistently have quite a lot of deadly earthquakes, dating back for
many years. From that list, Chile has been seeing pretty potent
earthquakes on a regular basis since 1905.
I'm mighty glad to hear that Alvaro is OK, and that things weren't too
disastrously shaken up, for him.

I don't think the number of positive events factors into it. It's that
the law of large numbers kicks in and the rate of death is pretty much
constant. Every now and then there's an atypical weekend for a given
town or city and the death toll spikes and people do in fact notice.
Suddenly the news is filled with stories about the carnage the prior
weekend and various imagined causal factors just like when the stock
market goes up or down and the news people try to explain why.

Well there is also a difference here. Because there is an active
opponent in the terrorism case the security has non-linear game-theory
effects. In the car safety case you could spend 10x as much money and
reduce accident death rates by 1/10th. But there's a point of
diminishing returns and an optimal value somewhere. In the case of
terrorism it may well be the case that if you spend any money on
security you must spend a lot of money for it to reach the threshold
at which terrorists redirect their attacks elsewhere.
Earthquakes are of course not in that category. They just occur rarely
enough and then our perception of their severity is heavily influenced
by where they occur so clumpings are just inevitable.
