7. DATASET OVERVIEW

7.1 Abstract

* the data of volcanic seismic observation by Japan Meteorological Agency

* Hourly data of crustal strain: Hourly mean value of Volume strain observed by borehole type volume strainmeters, normal strain of each direction observed by multi-component borehole type strainmeters.

* CMT solutions in Japan Meteorological Agency : CMT(Centroid Moment Tensor) solutions

* Nodal plane solutions in Japan Meteorological Agency : Nodal plane solutions determined by P-wave initial motion polarity, and P-wave initial motion polarity of observation points

* Arrival time data : The arrival time of P phase and S phase and the maximum seismic wave amplitude at seismic stations in Japan

* Hypocenter data : Focal parameters and magnitude determined by observation data at seismic stations in Japan

* Seismic intensity data observed by JMA seismic intensity meter.

* the volcanic plume data, "height, length, width, direction, color and other", witch observed by Japan Meteorological Agency

* the monitoring data of air shock with a low frequency microphone by Japan Meteorological Agency

* the volcanic grand deformation data, witch observed by Japan Meteorological Agency,"include expansion and contraction of a volcanic body"
