タイトル（英）：	EARTHQUAKE OBSERVATION USING HOT SPRING BOREHOLE AT SAN-NO, NAGOYA AND GROUND STRUCTURE MODEL OF THE NOBI PLAIN
抄録（英）：	This report briefly describes about the results of survey and earthquake observation at the San-no hot spring borehole in the Nagoya city, the microtremor array surveys and the earthquake simulation analysis in the Nobi plain. It was confirmed that a base rock, consisting of hard granite; Vs=2.8km/s, under the San-no site lied at a depth of about 670m and S wave velocity distribution was also obtained from the PS logging along the borehole. We observed many earthquake records at the base rock and surface ground, including the small earthquakes happened under the Nobi plain. The microtremor array method was verified by comparing the S wave velocities estimated from this method with those obtained by PS logging along the San-no borehole. Then, twelve sites in all were surveyed on the Nobi plain. Consequently, it was clarified that the abrupt incrimination of base rock exists beneath the western area of Nagoya city, though the base rock at eastern part is about from 500m to 600m in depth. Several cross section models were made up in NE-SW and NW-SE directions across the Nobi plain. The simulation analyses by using 2-D finite element method well reproduce the observational waves for a long distance earthquake, however a good consistency is not obtained for a very short distance earthquake, indicating the necessity of further detailed examination about ground structure in the Nobi plain.
