RST Apology to Tasmanian Aboriginal people 2021.
The Macquarie Ridge extends over 1200 km from southern New Zealand to a triple junction of the Pacific,
Australian and Antarctic plates near 61 ° 30’S, 161 0 00’E. Large earthquakes occur frequently on the ridge, with an average return period of one year for an event of magnitude 6.2 or more and 10 years for one of magnitude 7.2 or more.
Analysis of 16 focal mechanism solutions indicates that the direction of the principal stress is consistently horizontal, and along the northern and central ridge segments it strikes east-west. In the southern ridge segment, its azimuth is poorly defined but appears to rotate towards the northeast with increasing southerly latitude. North of 51 oS, the characteristic fault displacement is along reverse dip-slip faults, whilst south of 51 0 S, fault motion is predominantly by right-lateral strike-slip; throughout, the strike direction is parallel to the ridge axis.

The Royal Society of Tasmania acknowledges, with deep respect, the traditional owners of this land, and the ongoing custodianship of the Aboriginal people of Tasmania. The Society pays respect to Elders past, present and emerging. We acknowledge that Tasmanian Aboriginal Peoples have survived severe and unjust impacts resulting from invasion and dispossession of their Country. As an institution dedicated to the advancement of knowledge, the Royal Society of Tasmania recognises Aboriginal cultural knowledge and practices and seeks to respect and honour these traditions and the deep understanding they represent.
