There is no reason why it can't be done, except the cost of the needed
recording drums, and such... the sensors can be homebuilt, if you are
good at electronics, but that 24 hour drum chart recorder is not cheap,
unless you have one handy already.
  I am currently using a military surplus seismic motion detector for
quake alert (cost about 125 bucks, surplus) and you can make a wake-up
alarm with a 6 dollar radio shack car vibration alarm, a sonalert, and
a 9 volt battery which will go off at any even slightly feelable quake.
  Another home method is to use a phonograph cartridge with a mass clipped
to the place where the needle would rest, and feed it to an amp with about
a gain of 500 or so, then to a meter or chart, as you like. The mass is
only a few grams or so.

By the way, if there is a mail-list for seismic news, I would like to be
placed on it...
  I am a volunteer with the San Diego Office of Emergency Management, and
like to follow news about research into quakes and such.
