Apparently, these are normal earthquake swarms for that area and occur regularly.  Last years swarm accounted for over 2400 quakes over a 3 month period of time.
I read that link.  You have to admit, it wreaks of sensationalism.
I mean, this swarm started on February 8.  Yes, it has averaged about 20 quakes a day for 10 days, yet the express is just now reporting the world may be coming to an end?  What about the 2400 quakes which happened last year?
