Macquarie Island, and the steep underwater mountain chain from which it rises, have become a Southern Ocean seismic observatory to better understand earthquakes and tsunamis caused by the collision of continental plates.

The array of 32 seismometers, deployed across the tectonically active area known as the Macquarie Ridge Complex (MRC), are part of a project led by the Australian National University (ANU) – with help from Australian Antarctic Program expeditioners – to study the mechanisms causing submarine earthquakes in the region.

A team of three cold climate geotechnical specialists are about to commence winter investigations near Australia’s Davis research station in East Antarctica, to gather data on soil, rock and ice in the area proposed for a new aerodrome.
This information will assist in informing the geotechnical and engineering design, delivery and construction methodology of the Davis Aerodrome Project (DAP), subject to approval.

DAP Project Manager, Stuart Gibson, said the site investigation activities will provide clarity around conditions at the proposed runway site and will help inform extensive environmental considerations going forward.
