Considering that a tsunami is a long-wavelength ocean wave described by 2-D linear long-wave equations, and that the sea-bottom topography acts as a set of point-like scatterers, we use a first-order Born approximation in deriving the tsunami Green\u0027s function having coda waves. The scattering pattern is non-isotropic and symmetrical with respect to the forward and backward directions. We indicate a retrieval process which shows that the derivative of the cross-correlation function of wavefields at two receivers with respect to the lag time gives the tsunami Green\u0027s function when point noise sources generating continuous ocean waves are distributed far from, and surrounding, the two receivers. Note that this relation between the cross-correlation and the Green\u0027s function is different from the case in which uncorrelated plane-wave incidence from all directions is assumed to be continuous ocean waves. The Green\u0027s function retrieved from continuous ocean waves will be used as a reference to examine the validity of the Green\u0027s function obtained by numerical simulations.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "TERRA SCIENTIFIC PUBL CO", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.5047/eps.2011.08.020"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1343-8832", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tatsuhiko Saito", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Jun Kawahara", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Retrieval of long-wave tsunami Green\u0027s function from the cross-correlation of continuous ocean waves excited by far-field random noise sources on the basis of a first-order Born approximation", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Retrieval of long-wave tsunami Green\u0027s function from the cross-correlation of continuous ocean waves excited by far-field random noise sources on the basis of a first-order Born approximation", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5885", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5885", "relation": {}, "relation_version_is_last": true, "title": ["Retrieval of long-wave tsunami Green\u0027s function from the cross-correlation of continuous ocean waves excited by far-field random noise sources on the basis of a first-order Born approximation"], "weko_shared_id": -1}
