Distributed Acoustic Sensing in Australia's Downward Looking Telescope
Seismic waves are being recorded in more detail than ever before. In this latest collaboration with the NASA Deep Space Network (DSN), researchers from The ANU and AuScope’s Earth Imaging and Sounding Program explain Distributed Acoustic Sensing (DAS) infrastructure .
Probing the Australian-Pacific Plate Boundary: Macquarie Ridge in 3D (Updated)
A team of Australian researchers are about to set off on a landmark voyage to discover more about the Earth beneath our oceans, and what triggers underwater earthquakes. Read live updates of the cruise as they go — both personal reflections and scientific background to the cruise.
Do Australian earthquakes matter?
People naturally focus on big news and Geo-scientists also pay more attentions to big earthquakes happening in plate boundaries rather than the 'boring' small earthquakes in stable continents. Does this mean the intraplate earthquakes are negligible in scientific research?
Imaging the full lithosphere with earthquake sources
When the seismic waves from a distant earthquake arrive in the vicinity of a seismic recording station they interact with the local structure and produce a variety of minor contributions accompanying the main arrival of a seismic phase.
Probing the Australian-Pacific Plate Boundary (Pt 5: Underwater array observatory at the Macquarie Ridge)
Three and a half days after our departure from Hobart, we arrived in just northeast of the Macquarie island and instantly proceeded with swathing – mapping the ocean floor in the north-eastern quadrant, in lines parallel to the Macquarie ridge.
