In order to obtain new images of crustal inhomogeneity beneath the southwest Japan arc, I propose an improved mapping method designed for sparse wide-angle refl ection data. The method, an improved form of the Common Scatter-Point (CSP) stacking method, has the advantages of both the Common Mid-Point (CMP) and CSP stacking methods, which means that it can add a migration effect to the CMP method, and has less of the ghost curves that results from the CSP method. When applied to two sets of wide-angle reflection data (the 1988 Kawachinagano-Kiwa profile and the 1989 Fujihashi-Kamigori profile), the method provided clear images of the subducting Philippine Sea plate and the island-arc’s lower crust. The main results are as follows: (1) Intra-plate seismic activity is concentrated within the oceanic mantle, which suggests that the oceanic mantle may be subject to dehydration embrittlement; and (2) The lower crust beneath the southwest Japan arc has strong inhomogeneity, with a wavelength ranging from several to a dozen kilometers, which may result from crustal reconstruction due to igneous activity that has occurred since the Cretaceous.

  • Revision of the Genus Anchycteis (Coleoptera, Ptilodactylidae) from Japan
    Elytra, Tokyo, New Series, 4 (2): 249–260 December 25, 2014 Revision of the Genus Anchycteis from Japan 249 Revision of the Genus Anchycteis (Coleoptera, Ptilodactylidae) from Japan Song-hwa HWANG and Hiroyuki YOSHITOMI Entomological Laboratory, Faculty of Agriculture, Ehime University, Tarumi 3‒5‒7, Matsuyama, 790‒8566 Japan Abstract The Japanese species of the genus Anchycteis are reviewed, and three species are recognized. Two junior synonyms, Anchycteis brunneicornis usori (NAKANE, 1958)=Anchycteis brunneicornis (LEWIS, 1895) and Anchycteis monticola brunneipennis (NAKANE, 1963)=Anchycteis monticola (NAKANE, 1952), are newly established. Epilichas miyatakei NAKANE, 1952 is transferred to the genus Anchycteis. Habitus, male and female antennae and genitalia, and distribution map are presented. Introduction The genus Anchycteis HORN, 1880 belongs to the subfamily Anchytarsinae CHAMPION, 1897 (LEE et al., 2005; SATÔ, 2006; also see BOUCHARD et al., 2011 for synonyms of this subfamily), and is represented by three species with two subspecies from U.S.A. and Japan (STRIBLING, 1986 b; SATÔ, 2006). From Japan two species and two subspecies are recorded (SATÔ, 2006), but they have not been revised and the definitions of two subspecies are not clear. In the present paper, we review the Japanese species of the genus Anchycteis. Material and Methods Materials. The specimens examined in this paper are preserved in the following institutes and museums: Ehime University Museum, Matsuyama (EUMJ); Systematic Entomology, Hokkaido University, Sapporo, Japan (SEHU). The holotype of the type species of the genus (Anchycteis velutina HORN, 1880) was checked in MCZBASE (the database of the zoological collections, museum of comparative zoology, Harvard University; http://mczbase.mcz.harvard.edu/guid/MCZ:Ent:8014).

A, 32(2), pp. 61–94, June 22, 2006 The Sawfly Genus Spinarge (Hymenoptera, Argidae) Hideho Hara1 and Akihiko Shinohara2 1 Hokkaido Forestry Research Institute, Koshunai, Bibai-shi, Hokkaido, 079–0198 Japan e-mail: [email protected] 2 Department of Zoology, National Science Museum, 3–23–1 Hyakunin-cho, Shinjuku-ku, Tokyo, 169–0073 Japan e-mail: [email protected] Abstract The genus Spinarge, previously represented by three Chinese species, is redefined to include 11 Palaearctic species, and is transferred from the Athermantini to the Argini of the Arginae. This genus is characterized by the fifth abdominal tergum with a dark median line (ϭin- conspicuous median groove) in the female and a long median process in the male. A key to the world species and descriptions or redescriptions of the following nine species are given: S. affinis sp. nov. from Japan, S. chrysoptera (Gussakovskij, 1935), comb. nov. from China, S. fulvicornis (Mocsáry, 1909), comb. nov. from Japan, Korea and China, S. flavicostalis sp. nov. from Japan, S. metallica (Klug, 1834), comb. nov. from Europe to Kamchatka, Primorskij kraj, Sakhalin and Korea, S. nigricornis sp. nov. from Japan, S. prunivora sp. nov. from Japan and Korea, S. pumila sp. nov. from Japan, and S. sichuanensis Wei, 1998, from China. Larvae are gregarious leaf feeders on broad-leaved trees such as Betula, Prunus and Sorbus. Key words : Hymenoptera, Argidae, Spinarge, new species. Spinarge Wei, 1998, is a small genus of the tergum. The process is a very peculiar and un- sawfly family Argidae (Hymenoptera), so far rep- questionably an apomorphic character state that resented by three Chinese species, S.

  • Okuike Pond and Okuyama Reservoir
    June 2014 （vol.202） The following articles are taken mainly from “Koho Ashiya” - the bulletin of Ashiya City (June 1st issue). It is, of course, a Japanese edition, and translated into English by a voluntary group from the Ashiya Cosmopolitan Association (ACA). Please understand that some phone numbers listed under the various events are staffed by people who may not speak English. ― Welcome to Garden City Ashiya – Okuike Pond and Okuyama Reservoir Going northward along the prefectural road from Kaimoribashi Bridge, then along the verdant road from Royu gate, you will find “Okuike Pond and Okuyama Reservoir” in the heart of the mountains. Okuike Pond was completed in the Edo era (around 1841) after more than 20 years of difficult excavation work by Sarumaru Matazaemon Yasutoki, the village chief at that time, with a wish to save the villagers who had been suffering from water shortage. Okuyama Reservoir was completed beside the Pond in 1972. Both are utilized as a water source by Ashiya City Okuyama Reservoir even now. Okuike Pond Okuike Pond Evacuation Drill – June 5 (Thurs.) 10:15 a.m. Place: Throughout the city Time: 10:15 a.m. Emergency Warning will be on air over loudspeakers and individual receiving stations, beginning with an alert chime and the announcement, “Kochira wa bosai Ashiya desu.” Your understanding and participation are appreciated. Contents: How to improve preparedness in an earthquake. “Shake out” drill to protect yourself during earthquakes.

(Received 1 April 1999; Accepted 12 Augtlst 2ooO) Eight species of the genus Paraleuctra are recognized in Japan, six of them being described as new herein: P. ezoensis from Hokkaido and P. ambulans, R similis, P. hokurikuensis, P. angulata, and P. concava from Honshu. An apterous and a short-winged species are included. A neotype is designated for LeLtctra okamotoa Claassen, 1936; this species is now transferred from RhQpatopsole to the present genus and is regarded as a senior subjective syn- onym of P, gracilis Kawai, 1967, Parale"ctra cercia (Okamoto, 1922) is re- described and regarded as a senior subjective synonym of both R foi:ficularis (Okamoto, 1922) and L, higashtyamae Kohno, 1965. Paraleuctra eiongata Kawai, 1967 is transferred to Rhqpalopsote, and P. nipponica (Okamoto, 1922) and Rhopalopsole gijtzensis Kohno, 1965 are transferred to Pertotrryia.

  • Influence of Crustal Lithology and the Thermal State on Microseismicity In
    Maeda et al. Earth, Planets and Space (2021) 73:173 https://doi.org/10.1186/s40623-021-01503-3 EXPRESS LETTER Open Access Infuence of crustal lithology and the thermal state on microseismicity in the Wakayama region, southern Honshu, Japan Sumire Maeda1* , Shinji Toda2, Toru Matsuzawa3, Makoto Otsubo4 and Takumi Matsumoto1 Abstract Here we investigate the infuence of the lithology and thermal state of the upper crust on earthquake distributions beneath the Wakayama region, southern Honshu, Japan, to better understand the infuence of crustal conditions on regional seismogenesis. The earthquakes are concentrated in the deeper sections of mafc belts and shallower sec- tions of pelitic belts, based on a comparison of relocated hypocenters and estimated subsurface geological structures. We compare the frictional properties of pelitic rocks and basalt, as obtained from petrological experiments, with the hypocenter depth distributions in pelitic and mafc belts to assess the control of crustal lithology on the depth extent of regional seismicity. The earthquake distributions are consistent with the temperature ranges over which the respec- tive rock types are expected to exhibit a velocity-weakening behavior, based on the petrological experiments. The results suggest that the occurrence of shallow intraplate earthquakes is controlled by the temperature- and lithology- dependent friction of the upper crust.
