抄録: The Noto Peninsula is characterized geologically by tilted blocks and active structures associated with block movements. We investigate the activity of microearthquakes to discuss the relationships between the distribution of hypocenters, together with the 2007 Noto Hanto earthquake, and geological structures such as tilted blocks and active structures in the Noto Peninsula. We use the hypocentral catalogue for 1986-2004 of the Kamitakara Observatory, Disaster Prevention Re-search Institute, Kyoto University. In the southern Noto Peninsula, we can recognize relatively high seismicity areas corresponding to the block structures. We find that the block structures seem to control seismicity, and a tilted block structure is related closely to the source fault of the 2007 Noto Hanto earthquake. These suggest that a block structure may be a basic unit of the generation for a large earthquake in the Noto Peninsula.
