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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"3019","relation_version_is_last":true,"title":["Rupture Process and Strong-Motion Generation of the 2014 Iquique, Northern Chile, Earthquake"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T01:29:22.316310+00:00"}
