The disturbances were created by light tapping on the lower part of a shear box. No displacement was observed from the tapping without shear load. From a series of experiments we found an acceleration in the horizontal displacement just after small vibration under shear. The acceleration indicates reduced shear resistance in the gouge layer, by about 3 % of the resistance just before the small vibration. This reduction in shear resistance seemed to be recovered soon and did not affect the long-term behavior of the gouge layer. The response of the vertical displacement to the small vibration depends on the amount of accumulated dilatation of the gouge layer. The mechanisms of shear resistance reduction and the variable response of the vertical displacement due to the vibration can be explained by the intrinsic feature of pillar-like structure of a force chain network in the gouge layer. Our results indicate that there might be dynamic triggering of fault motion due to shear resistance reduction of a gouge layer in a natural fault zone.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Geophysical Union", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1029/170GM14"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Takane Hori", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hide Sakaguchi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Naoto Yoshioka", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoshiyuki Kaneda", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Shear Resistance Reduction Due to Vibration in Simulated Fault Gouge", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Shear Resistance Reduction Due to Vibration in Simulated Fault Gouge", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4443", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4443", "relation": {}, "relation_version_is_last": true, "title": ["Shear Resistance Reduction Due to Vibration in Simulated Fault Gouge"], "weko_shared_id": -1}
