• Regional volcanology is defined as the field science to clarify the distributions and activities of volcanoes in time and space, which also gives the ground basis for all volcanological studies including physical volcanology and chemical volcanology. The detailed and trustful distribution of volcanoes in high quality can only be obtained by long-term, tedious field surveys that associate with fine laboratory analyses under feedback systems. The priority of field survey on sustaining high-quality volcanological study may not be reduced in future as well as at present, even if the laboratory techniques develop further more. One of the major purposes of regional volcanology is to visualize the subsurface structure of volcanoes and to clarify the past volcanic history which was in many cases obscured by the successive eruption deposits. Both of these two tasks require drill-hole data and geophysical exploration data in addition to adequate surface geology data. Intensive studies on a single volcano or a volcanic field throughout the synthesis of multidisciplinary data should be the key strategy in future as well as at present. Many hypotheses on the activities of volcanoes have been well examined in the cases where both main constituents of volcanoes and time-and-space distribution are clarified enough. Regional volcanology offers such test fields that contain high-quality geological data to the surrounding fields of science such as quaternary research, structural geology, and tectonics.
