  • Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan
    International Journal of Erosion Control Engineering Vol.5, No.2, 2012 Disaster Report Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan Kimio INOUE1, Toshio MORI2 and Takahisa MIZUYAMA3 1Sabo Frontier Foundation (Sabo-Kaikan, Hirakawa-cho 2-7-4, Chiyoda-ku, Tokyo 102-0093, Japan) Email: [email protected]) 2Sabo Frontier Foundation (Sabo-Kaikan, Hirakawa-cho 2-7-4, Chiyoda-ku, Tokyo 102-0093, Japan) 3Division of Forest Science, Graduate School of Agriculture, Kyoto University (Kitashirakawa, Sakyo-ku, Kyoto 606-8502, Japan) Large landslides or debris flows caused by heavy rainfall or earthquakes often block rivers in mountainous areas and form landslide dams. The area upstream of the landslide dam is submerged under water and the downstream area is flooded when the landslide dam breaks. In recorded history, as many as 22 landslide dams have formed upstream of the Shinano River and the Hime River, in the northern part of Nagano Prefecture in central Japan, and all except three have subsequently broken. This abundance of landslide dams is probably caused by the geotectonic background of this area, which is located at the western end of the “Fossa Magna” major tectonic line. In this study, we examined three large historical landslide dams and outburst disasters in the north Fossa Magna area.

  • New Prediction of Sediment-Related Disaster Critical Rainfall Using Meteorological Model WRF
    Symposium Proceedings of the INTERPRAENENT 2018 in the Pacific Rim New Prediction of Sediment-related Disaster Critical Rainfall Using Meteorological Model WRF Toshihide SUGIMOTO1, Toshiyuki SAKAI2 and Hiroshi MAKINO1* 1 NEWJEC Inc. (2-3-20 Honjo-Higashi, Kita-ku, Osaka 5310074, Japan) 2 Japan Weather Association (2-3-2 Minamisenba, Chuo-ku, Osaka 5420081, Japan) *Corresponding author. E-mail: [email protected] A large number of sediment-related disasters have recently occurred in Japan due to record heavy rains exceeding 1,000 mm in cumulative rainfall and concentrated heavy rains equivalent to an hourly rainfall of 100 mm. These heavy rainfall events are likely to increase in frequency because of the impact of an increase in water vapor content caused by rising temperatures associated with global warming. Today, sediment disaster alert information is made public to ready people for sediment disasters. However, since calculation is based on the actually measured rainfall, announcement is generally made just before a sediment disaster occurs. There is no sufficient time left before people can leave their homes for shelter. This is one of the major problems related to the current system of sediment disaster alert information announcement. In this research, we conducted rainfall prediction based on rainfall simulation that uses numerical calculation meteorological model Weather Research and Forecasting (WRF) as a new evaluation technique that predicts a rainfall event likely to cause a sediment disaster at an early stage or two to three days in advance and made a comparative review of the simulation results with recent rainfall events that actually caused sediment disasters.

Vol. XLII, No. 2, pp. 131-170, March 30, 1976 Geologic Study on the Myoko Volcanoes, Central Japan -Part 1. Stratigraphy--- By Kenji HAyATsu (Received October 24, l975) Abstract The Myoko volcanoes* constructed from the Yakeyama, Myoko, Kurohime, Iizuna, Madarao, and Sadoyama volcanoes, are situated in the boundary area between Nagano and Niigata prefectures, centralJapan. Most of the volcanoes are distributed along the anticlinal or synclinal axis ofthe basal Neogene strata. Except for the older volcanoes, Sadoyama and Madarao, the volcanic cones form a north-south trend, arranged at nearly equal intervals of about 8 km, and become younger in age toward the north. The migration of eruptive activity toward the north seems to be closely related with that ofthe movement ofthe underlying rock mass. "MYOKO" are the typical stratovolcano, except for the dome-shaped Yakeyama volcano• In particular, three volcanoes, the Myoko, Kurohime, and Iizuna, are "double" stratovolcano provided with a small summit caldera. They are similar to each other in shape, but are different from each other in growth history, petrography, and other characteristics. The Myoko volcano consists of an older and a younger volcanoes, and furthermore, the younger one stratigraphically consists of four groups, which correspond petrographically to a basalt-andesite series, respectively.

  • A Checklist and Bibliography of Parasites of Salmonids of Japan
    ;r c j . 3 $JJ#~,Sci. Rep. Hokkaido Salmon Hatchery, (41) : 1-75 (1987) A Checklist and Bibliography of Parasites of Salmonids of Japan Kazuya NAGASAWA*',Shigehiko URAWA", and Teruhiko AWAKURA*~ Abstract Information on the parasites of salmonids in Japanese waters that was published during the years 1889-1986 is assembled in the form of Parasite-Host and Host- Parasite lists with accompanying bibliography. Ninety-four named species of parasites (18 Protozoa, 5 Monogenea, 21 Trematoda, 7 Cestoidea, 19 Nematoda, 15 Acanthocephala, 1 Hirudinoidea, 1 Mollusca, 1 Branchiura, 5 Copepoda, 1 Isopoda) have been reported, and numerous other parasites not identified to species level are also included. The Parasite-Host list, arranged on a taxonomic basis, includes for each parasite species its currently recognized scientific name, and synonyms oc- curring in the literature, habitat (freshwater or marine), location of infection (site) within the host, species of host(s), known geographical distribution in Japanese waters, and the published source for each host and locality record. Where neces- sary, remarks and footnotes dealing with such topics as taxonomy, nomenclature, and misidentifications are included. The Host-Parasite list summarizes the species of parasites from each species of salmonid and their geographical distributions. Although taxonomic revision is not the aim of the checklist, the following three new combinations and one new synonym are proposed : Microsporidium takedai (Awa- kura, 1974) n. comb. for Nosemu tukedui ; Sterliudochonu ephemeridurum (Linstow, 1872) n. comb. for Cystidicoloides ephemeridurum ; and Salvelinema ishii (Fujita, 1941) new synonym of S. salvelini (Fujita, 1939) n. comb. for Metabronemu salvelini.
