A slip model derived from the waveform inversion using the low-frequency (0.02?0.125 Hz) velocities is characterized by a large slip area localized 50 km south of the epicenter with a peak slip of 10 m, and a deeper slip area with a peak slip above 2 m located below the coast. The main rupture of these areas started 25 s after the initial break generating two pronounced phases observed in most of the records. The landward slip area ruptured for about 10 s generating the first impulsive phase, while the offshore largest slip area ruptured for 20 s creating a longer duration phase observed later. Results from a back-projection analysis based on stacking of envelopes of 5?10-Hz accelerations indicate that the high-frequency radiation propagated down-dip towards the coast, reaching its maximum value from 25 s to 40 s, far away from the shallow main slip area obtained from low-frequency waveform inversion. Our results suggest a clear depth dependence of the seismic wave radiation during the Iquique earthquake.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "World Scientific Pub Co Pte Lt", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1142/s179343111640008x"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1793-7116", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Wataru Suzuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Nelson Pulido", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shin Aoi", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Rupture Process and Strong-Motion Generation of the 2014 Iquique, Northern Chile, Earthquake", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Rupture Process and Strong-Motion Generation of the 2014 Iquique, Northern Chile, Earthquake", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/3019", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "3019", "relation": {}, "relation_version_is_last": true, "title": ["Rupture Process and Strong-Motion Generation of the 2014 Iquique, Northern Chile, Earthquake"], "weko_shared_id": -1}
