Abstract
In Japan, 47 among 110 active volcanoes are monitored by the Japan Meteorological Agency on a 24-h basis, and several universities develop volcanological studies with their own volcano observatories at some of the recently active volcanoes. Some other research institutes also study several volcanoes for their own research purposes. The primary mission of the Japanese Coordinating Committee for the Prediction of Volcanic Eruptions is to evaluate the activities of volcanic unrest by integrating various data from various agencies; this system has worked fairly well for most of the recent volcano crises. Especially integration of seismicity and crustal deformation data from various institutions has worked promisingly to predict the onset of vulcanian explosions in some volcanoes recently activated. The reason why this kind of interagency cooperative system has worked so far is because volcanic activity in Japan has been fairly low for almost a hundred years. A new centralized system to monitor, analyze, and issue adequate volcanic information is desired to prepare for the accelerated activity of Japanese volcanoes in the near future.
