While geodetic and geophysical analyses have characterized the extent of surface rupture and faulting mechanism respectively, a comprehensive aftershock characterization has yet to be performed. Data has been acquired from a 12-station temporary seismic network deployed jointly by the ANU and Geoscience Australia (GA), collected from five days following the mainshock to early October. Taking advantage of enhanced automatic detection techniques using the SeisComP3 real-time earthquake monitoring software within the National Earthquake Alerts Centre (NEAC) at GA, we have developed a comprehensive earthquake catalogue for this mainshock-aftershock sequence. Utilising the NonLinLoc location algorithm combined with a Tennant Creek-derived velocity model, we have preliminarily located over 5,800 aftershocks. With additional spatio-temporal analyses and event relocation, our objective will be to use these aftershocks to help delineate the geometry of the headwall rupture along the Woodroffe Thrust. These high-resolution aftershock detection techniques are intended to be implemented in real-time within the NEAC following future significant Australian intraplate earthquakes.\nThis paper was presented at the Australian Earthquake Engineering Society 2021 Virtual Conference, Nov 25 \u2013 26.", "num_resources": 2, "num_tags": 9, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/automated-relocation-of-the-petermann-ranges-aftershock-sequence", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[129.0, -26.5], [130.5, -26.5], [130.5, -25.0], [129.0, -25.0], [129.0, -26.5]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[129.0, -26.5], [130.5, -26.5], [130.5, -25.0], [129.0, -25.0], [129.0, -26.5]]]}", "state": "active", "temporal_coverage_from": "2016-05-20 00:00:00", "temporal_coverage_to": "2017-02-01 00:00:00", "title": "Automated Relocation of the Petermann Ranges Aftershock Sequence", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "f12e6bf2-ae58-45f6-86b5-fd6616a1142b"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T08:29:34.129414", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Link to Conference Proceedings", "format": "HTML", "hash": "", "id": "9e0ccf72-413a-45d4-8f2d-2e7ed5f45428", "last_modified": null, "metadata_modified": "2025-10-16T08:29:34.115092", "mimetype": null, "mimetype_inner": null, "name": "Link to Conference Proceedings", "package_id": "01b51e49-99e9-4154-8ea1-d94d6585fb07", "position": 0, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://aees.org.au/downloads/conference-papers/2021-2/", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T08:29:34.129419", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Link to Presentation", "format": "PDF", "hash": "", "id": "78d46b2e-87b3-465d-ae24-fb9772d2cc93", "last_modified": null, "metadata_modified": "2025-10-16T08:29:34.115246", "mimetype": null, "mimetype_inner": null, "name": "Link to Presentation", "package_id": "01b51e49-99e9-4154-8ea1-d94d6585fb07", "position": 1, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://aees.org.au/wp-content/uploads/2022/02/14-Gregory-Brenn.pdf", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "2016 Petermann Ranges earthquake", "id": "132c2254-e231-430e-8137-a5ea407746a5", "name": "2016 Petermann Ranges earthquake", "state": "active", "vocabulary_id": null}, {"display_name": "Aftershock Analysis", "id": "0cb028dd-af27-4708-8fc1-795a2b0203ed", "name": "Aftershock Analysis", "state": "active", "vocabulary_id": null}, {"display_name": "Australian earthquakes", "id": "a0aeca07-d769-4492-90c8-b6c1d57966c6", "name": "Australian earthquakes", "state": "active", "vocabulary_id": null}, {"display_name": "EARTH SCIENCES", "id": "927af2a7-7457-45c2-bd55-10000fd09c14", "name": "EARTH SCIENCES", "state": "active", "vocabulary_id": null}, {"display_name": "Earthquake Engineering", "id": "2c291903-19dd-4903-add6-54cd41391cec", "name": "Earthquake Engineering", "state": "active", "vocabulary_id": null}, {"display_name": "Natural Hazards", "id": "5a00d6e7-b91b-4c8a-aba2-40aa3f4a606b", "name": "Natural Hazards", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}, {"display_name": "SeisComP", "id": "9f0e3690-ef24-4917-9996-cf736ed1f100", "name": "SeisComP", "state": "active", "vocabulary_id": null}, {"display_name": "earthquake aftershocks", "id": "c5876b44-79cf-47a6-afb6-c9b91bcdd443", "name": "earthquake aftershocks", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
