From the volcano-energetics point of view, it is very important to evaluate the velocity, direction and distribution of ejected volcanic blocks. However, in most cases, it is hard to measure directly such quantities during the eruption. Therefore, th

The northern part of Hokkaido (Dohoku region) is recognized as the boundary region between the Okhotsk and Amurian plates. In this region, strain concentration is reported based on triangulation and GPS observations. However, there had not been obser

Spatial distribution of volcanic blocks, as well as landing distance from a crater, landing angle and diameter of the blocks has been well investigated on and around the crater in cases of the 1938 Asama and the 1977 Usu eruptions by some researchers

Many researchers have studied the thermal state of the crust and the upper mantle and its tectonic implications in Hokkaido, Japan. Terrestrial heat flow data have revealed the following characteristic features: (1) High heat flow (84〜125 mW/m2) is

The energy source of volcanic activity is the heat of magma. Heat discharge rate on the initial stage of Usu 2000 eruptive activity was estimated to be around 1×109 J/sec, that was over one order higher than that on the initial stage of the 1977 act
