At the MeSO-net station, a three-component accelerograph is installed at the bottom of a 20-m deep borehole.  To analyze horizontal component waveforms observed at a borehole-type seismic station, we first have to know the azimuth of the seismometer.  In this study, based on cross-correlation analyses of long wavelength seismograms with a high S/N, we estimate sensor azimuths at MeSO-net stations.  As reference stations, we use seismograms observed by NIED F-net broad-band seismographs and Hi-net tiltmeters.  At more than 80% of stations, N-components of seismographs are within ±10° from magnetic north.  We confirm that the sensors at three stations are rotated more than 90°.  Although our results agree well with results estimated using P-wave first motion of a local earthquake, there are systematical azimuthal differences between two results at stations distributed in the northern Kanto region.  Because the subducting Pacific slab lies beneath the Kanto region, this feature may indicate that the diffracted wave passing through the high-velocity slab was observed as a first pulse at stations located in the northeastern Kanto region.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"123626","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shiomi,
