[1] The Japan Meteorological Agency (JMA) has started
the practical service of Earthquake Early Warning (EEW)
and a very dense deployment of receiving units is expected
in the near future. The receiving/alarm unit of an EEW
system is equipped with a CPU and memory and is on-line
via the internet. By adding an inexpensive seismometer and
A/D converter, this unit is transformed into a real-time
seismic observatory, which we are calling a home
seismometer. If the home seismometer is incorporated in
the standard receiving unit of EEW, then the number of
seismic observatories will be drastically increased. Since
