Australian paleoseismology: towards a better basis for seismic hazard estimation

Annals of Geophysics (2009)

Dan Clark K. McCue

Probabilistic seismic hazard analyses in Australia rely fundamentally on the assumption that earthquakes recorded in the past are indicative of where earthquakes will occur in the future. No attempt has yet been made to assess the potential contribution that data from active fault sources might make to the modelling process, despite successful incorporation of such data into United States and New Zealand hazard maps in recent years. In this paper we review the limited history of paleoseismological investigation in Australia and discuss the potential contribution of active fault source data towards improving our understanding of intraplate seismicity. The availability and suitability of Australian active fault source data for incorporation into future probabilistic hazard models is assessed, and appropriate methodologies for achieving this proposed.

South Australian earthquakes during 1976 and 1977

Journal of the Geological Society of Australia (1979)

K. McCue D. J. Sutton

Abstract During 1976 and 1977, 120 earthquakes occurred in South Australia which were large enough to be recorded by the University of Adelaide seismograph network, and subsequently located. Only four epicentres lie outside the recognised seismic zones of the Adelaide Geosyncline, Eyre Peninsula and the Southeast Zone; only four of the earthquakes had magnitudes (ML) greater than 4. Fault‐plane solutions for three of the events within the Geosyncline suggest a direction of principal stress which is a northeast southwest compression. Notes Present address: The Geophysical Observatory, Box 323, Port Moresby, Papua New Guinea.

Australia: historical earthquake studies

Annals of Geophysics (2009)

K. McCue

Historical studies of earthquakes in Australia using information dating back to 1788 have been comprehensive, if not exhaustive. Newspapers have been the main source of historical earthquake studies. A brief review is given here with an introduction to the pre-European aboriginal dreamtime information. Some of the anecdotal information of the last two centuries has been compiled as isoseismal maps. Relationships between isoseismal radii and magnitude have been established using post-instrumental data allowing magnitudes to be assigned to the pre-instrumental data, which can then be incorporated into the national earthquake database. The studies have contributed to hazard analyses for the building codes and stimulated research into microzonation and paleo-seismology.

Revised hazard assessment for Afulilo Dam, Samoa

Geological Society London Engineering Geology Special Publications (2016)

R. Goldsmith K. McCue

Abstract Afulilo Dam was built as part of a hydroelectric scheme to augment the power supply for the island of Upolu, Samoa. The 23 m high concrete gravity dam sits on the crest of a waterfall that once drained an intermontane basin. Initially, concerns were expressed about a possible active fault through the dam site linked with a larger fault across the island. This assertion was refuted but not tested by the owners, and the dam came into operation as planned. This issue was again reviewed in 2009–10 as part of an environmental and power augmentation study. The opportunity was also taken to test the compliance of the dam with accepted international practices. Additional regional geological assessments, a review of the seismic data and further drilling at the dam site provided data to improve the geological model for the dam site. It is concluded and confirmed that there is no clear evidence for the existence of such faults. If they do exist, they are not active and therefore not significant for the safety of the dam.

The Lake Edgar Fault: an active fault in Southwestern Tasmania, Australia, with repeated displacement in the Quaternary

Annals of Geophysics (2009)

K. McCue Russ Van Dissen George R. Gibson Vagn H Jensen B. W. Boreham

The Lake Edgar Fault in Western Tasmania, Australia is marked by a prominent fault scarp and is a recently reactivated fault initially of Cambrian age. The scarp has a northerly trend and passes through the western abutment of the Edgar Dam, a saddle dam on Lake Pedder. The active fault segment displaces geologically young river and glacial deposits. It is 29 ± 4 km long, and dips to the west. Movement on the fault has ruptured the ground surface at least twice within the Quaternary and possibly the last ca. 25 000 years; the most recent rupture has occurred since the last glaciation (within the last ca. 10000 years). This is the only known case of surface faulting in Australia with evidence for repeated ruptures in the Late Pleistocene. Along its central portion the two most recent surface-faulting earthquakes have resulted in about 2.5 m of vertical displacement each (western side up). The Lake Edgar Fault is considered capable of generating earthquakes in the order of magnitude 61/2-71/4. The Gell River Fault is another fault nearby that was apparently also active in the Late Pleistocene. It has yet to be studied in detail but the scarp appears to be more degraded and therefore older than the most recent movement on the Lake Edgar Fault.

Earthquakes and Crustal Stress in the North Bismarck Sea

K. McCue

Three small plates, the North and South Bismarck Sea plates and the Solomon Sea plate, separate the con verging Pacific and Australian plates in the Papua New-Guinea - Solomon Islands region. Most of the shallow seismic energy released in the region occurs along the Solomon/South Bismarck Sea plate boundary south of New Britain. The least seismically active boundary is that between the Pacific/Caroline and North Bismarck Sea plates. Neither the eastern nor the western end of the North Bismarck Sea plate is clearly defined, but both may be unique trench-trench-trench-transform quadruple junctions. Focal mechanisms of three earthquakes along the northern boundary of the North Bismarck plate have a significant north-northeasterly thrust component. By comparison, earthquakes along the Solomon/South Bismarck Sea and Solomon/Pacific plate boundaries, and those within the Caroline plate, have similar thrusttype mechanism along a northeasterly direction. Seismological evidence does not show that the Mussau Trench along the Caroline/Pacific boundary is an active subduction zone.
