In total 4747 samples of 329 macrolepidopterous moth species were obtained in the surveys conducted at Yosomi Hill and at the crater basin of Mt. Usu in 1984. The level of species diversity was almost the same throughout all seasons. - (SGA)

The bee fauna was surveyed on and around Mt. Usu in 1984, six years after the 1977-78 eruptions of this volcano which has caused faunal and vegetational damage especially around the mountaintop area. In total 46 species of 6 families were obtained

The 1977-1978 eruptions of Mt. Usu, Hokkaido, altered erosion regime of its summit atrio through destruction of pre-existing vegetation, new tephra deposition and crustal deformation, resulting in heavy relling and gullying. The pattern, initial
rapid erosion followed by an exponential decline was observed for several other volcanoes, indicating rapid adjustment of a slope to the new erosion-sedimentation regime.

This paper describes the aspects and sequences of erosion and mudflows (rain lahars) at UsuVolcano after the burst of the 1977-1978 eruption, on the basis of field work carried out by the authors from August 1977 to December 1979. An event
The aim of this paper is to evaluate the effect of volcanic events on glaciations on the Tateyama Volcano during the last glacial period. For this purpose, this paper describes the distribution and stratigraphic relationships of the volcanic ejecta
, glacial sediments and landforms on the volcano, and examines the relation between the height or size of the Tateyama Volcano and the glacier extent in each glacial stage.
Chemical and isotopic compositions of spring water around Asama volcano, central Japan
This paper discusses the chemical evolution and the recharge elevation of spring water by using major dissolved components and isotopic composition around Asama volcano. In addition the A. will provide the conceptual model of groundwater flow system

From the 17 big volcanoes of the Cascade Mountains 6 are certainly active and 4 are certainly dormant. The others are somewhere between these extremes. The Cascade Mountains is a unique volcanic range with magma sources from colliding plates (acidic
Geomorphological maps for Japanese volcanoes by Geographical Survey Institute, Japan

Geographical Survey Institute is going to produce Land condition maps of volcano about active volcanoes given the priority by the Geodesy Council. This paper introduces these land condition maps of volcano and other geomorphological maps
for the research of volcanic disaster, especially the research of debris avalanche on Bandai Volcano.
The structure and geomorphology of the Dashgil mud volcano, Azerbaijan
The large-scale and small-scale structure and geomorphology of the active Dashgil mud volcano in central Azerbaijan, have been studied. Through historical records it is known that this mud volcano has major eruptions every 6-32 years. The activity
observed during 2 field trips in 1995, consisted of low-energy venting and debouching of mud, water, oil, and gas from 3 mud pool (salses) and about 20 individual cones (gryphons) located on the summit plateau of the mud volcano. The internal structure
of the mud volcano and the processes responsible for the observed Dashgil geomorphology are discussed. The natural contribution of atmospheric greenhouse gases from the world's mud volcanoes is highly significant.

The AA. describe geocryological conditions (active layer depths, permafrost temperatures, ground thermal properties and cryostratigraphy) in the Klyuchevskaya volcano group and estimate the spatial distribution of permafrost using a simple

Drainage on the north and west flanks of the Miocene Lyttelton Volcano does not have the expected radial and consequent pattern. It is proposed that the term anteconsequent, previously used in the context of orogenesis and erosion, should
be extended to cover the situation described on the Lyttelton Volcano.
The aim of this paper is to single out the relationships among the present landforms, their structural arrangement and the volcanic history of Central Italy. The morphological characteristics of the Roccamonfina volcano were examined through field
The Monte Vulture volcano is located on the eastern border of Southern Apennines at the inner margin of the Bradanic foredeep. A multi-disciplinary method taking into account geological, petrographic, volcanological and morphological aspects
The volcano-tectonic map of Etna volcano, 1:100.000 scale : an integrated approach based on a morphotectonic analysis from high-resolution DEM constrained by geologic, active faulting and seismotectonic data

A new volcano-tectonic map of Etna volcano has been compiled through a morphotectonic analysis performed with detailed field mapping, high-resolution DEM and orthoimages, constrained by seismotectonic data. In this study, the AA. present
a homogeneous mapping of the volcano-tectonic and tectonic elements on the whole volcano, consistent with the updated knowledge on the geology and active tectonics observed in historical times. Finally, a seismotectonic model summarises the information regarding
