Fluvial geomorphological development associated with MIS 5e–4 sea-level fluctuations in the lower reaches of the Kinu River, Japan
Discovery of Riverine Dunes along the Nagara and Ibi Rivers and Identification of Their Sediment Provenance
On the Nobi Plain, all currently recognized riverine dunes are limited to the Kiso River and its former distributary, the Saya River; no riverine dunes have been reported along the Nagara and Ibi Rivers. Grain-size analyses of sediments from alluvial fans, riverine dunes, and natural levees in the plain are conducted and compared with results for riverine dune sediments from the Nakagawa lowland and coastal dune sand from Otake beach, Kanto Plain…
Holocene Depositional Environmental Changes and Vertical Deformation Trends at the Mano River Lowland, Southern Pacific Coast of Northeastern Japan
Although temporal inconsistency in vertical deformation between long-term (> 103 years) uplift and short-term (101-102 years) subsidence along the Pacific coast of northeast Japan has been discussed in relation to cycles of megathrust earthquakes by some researchers, the fragmentary distribution of Pleistocene marine terraces and sparsity of studies on Holocene coastal geology indicate a lack of data on long-term vertical deformation at the occur…
Reconsidering Geoscience History in Twentieth-Century Japan by Deciphering the Diary
The historiography of geoscience in the 20th century in Japan is reconsidered through 57 volumes of diaries (1914-1963) of Mochizuki Katsumi (1905-1963), a geology professor at Shizuoka University, from the following four viewpoints: 1) Scientific thought of geotectonics: Considering Mochizuki's own theory of geotectonics from his relations with other researchers such as Otuka Yanosuke (1903-1950), professor at the Earthquake Research Institute a…
Comparison of Geomorphological Land Classification Maps with Flood Hazard Maps at Hachinohe Plain, Aomori Prefecture
To present meaningful information about the progress of flood hazard prediction at the alluvial plain, first, the relationships between geomorphological land classifications of the Hachinohe plain, Aomori Prefecture, conducted for three different periods, are considered; then, the relationships between landforms and flood hazards are discussed through a comparison of geomorphological land classification maps with flood hazard maps of the plain. A…
Reexamination of the Fluvial Terrace Development in the Nagatoro Gorge and the Development of Longitudinal Profile of the Ara River in the Kanto District, Central Japan
Millennial-scale crustal movements inferred from Holocene sedimentary succession of the Omoto plain, northern Sanriku coast, Northeast Japan
Effects of longitudinal valley slopes on runup of the 2011 Tohoku tsunami on the Sanriku coast, northeastern Japan
Holocene development of mountain wetlands within and outside of landslide in the Hachimantai volcanic group, northeastern Japan
Tributary effects on fluvial terrace development since the last interglacial in the upper Tama River valley, central Japan
Effects of topography on particle composition of 2011 tsunami deposits on the ria-type Sanriku coast, Japan
Eustatic and regional tectonic controls on late Pleistocene paleovalley morphology in the central Kanto Plain, Japan
Subsidence along the central to southern Sanriku coast, northeast Japan, near the source region of the 2011 Tohoku-oki earthquake, estimated from the Holocene sedimentary succession along a ria coast
Reconstruction of Lake Balkhash levels and precipitation/evaporation changes during the last 2000 years from fossil diatom assemblages
Magnitudes of sea-level falls at lowstands of the past 900,000 years inferred from gravels underlying the Nobi Plain, central Japan
Last 900 ka sea-level changes recorded in shallow marine and coastal plain sediments of the Nobi-tilted basin, Japan
Holocene climatic changes of the Balkhash lake region, Kazakhstan reconstructed from high-resolution XRF scanning analyses of the lake sediments coupled with geomorphic investigations of the catchment…
Last 600 ka terrestrial environment changes reconstructed from analysis of the Uwa Basin-fill Sediment, SW Japan
Reconstruction of Holocene environmental changes in the Kiso-Ibi-Nagara compound river delta, Nobi Plain, central Japan, by diatom analyses of drilling cores
