Funai Fault is a major normal fault along the southern margin of the tectonic basin. In order to estimate the activity of this fault, sedimentary facies, diatom assemblages, and radiocarbon ages of 17 terrestrial plant fragments and 4 marine carbonate samples were determined from seven drill cores. Based on the analysis, three sedimentary facies, namely delta front, delta plain, and artificial soil, were identified. These accumulation and defor-mation structures were imaged by ground penetrating radar profiling. Based on the results, the latest seismic event was identified at 800 to 400 cal BP based on the depositional ages and diatom assemblages from the uppermost mud layers in the delta plain sediment. The previous event was also identified at ca 2,100 cal BP on the basis of the vertical displacement of the lower mud layer in the delta front sediment. The recurrence interval was calculated at ca 1,700 years.","PeriodicalId":106287,"journal":{"name":"The Quaternary Research (daiyonki-kenkyu)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134382090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surface of the slope is composed of thick loam layer of approximately 10 m in thickness. The ground in the residential area has been arti-ficially modified for cultivated land, an ice-skating rink, and housing in the last three decades. Both horizontal and vertical displacements are recognized along most of the cracks. The former are several to thirty centimeters ; the latter are one meter or less. They are mainly E-W to ENE-WSW in strike, and a remarkable one extends more than 150 m long with northward sinking in the central portion of the area. Cracks with vertical displacements tend to appear in the northward zone of this major crack. The zone almost coincides with the outer periphery of the previous skate rink, so it is highly likely that sliding of embankment mate-rials along the cut slope of the rink occurred at the time of construction of the residential area. Therefore, such cracks might have been formed as settlement or displacement due to earthquake vibration.","PeriodicalId":106287,"journal":{"name":"The Quaternary Research (daiyonki-kenkyu)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123194647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this confirmation, four concepts from the view-point of Quaternary research and creating a hazard map for landslide disasters were summarized in the case study area including the volcanic fan of Mount Unzen. The history of landform development with landform processes, such as deposition and erosion within a period of the order of 10 2 years, can be used as a basic material for area classification to landslide disasters. Spatial analysis consisting of interpreting of elevation changes as landform process and over-laying the results from the oldest to the youngest means the construction of landform development. Spatial analysis, reclassifying the geographic information interpreted as a set of landform processes including its type, size, and sequence means the classification of micro-landforms. From the results of landform analysis using DEM on the volcanic slope, it is easy to understand the area safety based on micro-landforms and the area in which to be aware of debris and water movement from watersheds.","PeriodicalId":106287,"journal":{"name":"The Quaternary Research (daiyonki-kenkyu)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128517394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
