On July 3 2021, a debris flow caused by a landslide from a landfill occurred along the Aizome River in the Izusan area of Atami City, Shizuoka. In this study, debris flow deposits and soil samples were characterized in terms of their sedimentology and geochemically analyzed.

Ion cyclotron emissions (ICEs) due to deuterium-deuterium fusion-product (FP) ions on JT-60U are studied. ICE due to H-ions is identified from the difference of the toroidal wave number of 2nd ICE(D). The parameter dependence for the appearance of ICE(H) is investigated from the experimental conditions and also is studied by using "Escape Particle Orbit analysis Code (EPOC)".

The understanding of spontaneously excited waves in plasmas with anisotropic velocity distributions is the main purpose of this presentation. In JT-60U, the ion cyclotron emissions (ICEs) due to fusion product ions have been experimentally observed. By using the local dispersion relation in hot plasmas, the excitation of slow and fast Alfv
n waves are evaluated. The excitation mechanism for ICEs due to fusion product ions are discussed.

Fluctuations in the ion cyclotron range of frequency are investigated both on GAMMA 10 and JT-60U. Ion cyclotron emissions (ICEs) due to deuterium-deuterium fusion-product (FP) ions on JT-60U are described. ICE due to H-ions is newly identified. ICE(T) with lower frequency has larger wave numbers than ICE (
He) in the same discharge. The excitation of slow Alfvn waves is elucidated for the first time as the mechanism for ICE due to T-ions. The anisotropy of T-ions at the outer plasma edge is evaluated by using Escape Particle Orbit analysis Code (EPOC).

In fusion-oriented devices, Alfven waves are spontaneously excited due to the existence of non-thermal energy component and anisotropy in the ion energy distribution. In the ion cyclotron range of frequency (ICRF), Alfven ion cyclotron (AIC) modes are spontaneously excited due to the strong temperature anisotropy and fast Alfven waves are observed as the ion cyclotron emission (ICE) in the burning plasma experiments. Experimental observations in GAMMA 10 and JT-60U are reviewed.
