Abstract
We installed a portable broadband seismometer (Streckeisen STS-2)
at the Sakurajima volcano, which has been very active in the
recent years.
The recorded seismograms show a wide variety (both in temporal and spectral
contents) of seismic events, from explosions to tremors, and exhibit
the importance of such broadband seismometry at volcanos.
We present examples of seismograms
to show the potential of broadband seismic observation
in monitoring volcanic activities.
