Inter-source correlograms yield coherent signals upon careful consideration of source mechanisms and source-receiver geometry, affording new means of characterizing planetary interiors.
2022 was an exciting year for deep Earth and planetary sciences communities.
Distributed acoustic sensing, or DAS, is a newly developed passive seismic technology that can transform telecommunication fibre-optic cable into linear arrays of ground motion sensors.
Last week's Woods Point earthquake in Victoria was a quite a surprise for most Australians outside the geophysical community and even among Earth scientists, an event of this magnitude was unexpected.
On the morning of September 22, a magnitude-5.9 earthquake struck approximately 130 km northeast of Melbourne. Seismic waves were felt in Melbourne, Canberra, Sydney and Adelaide, and as far south as Tasmania.
How we built a simple dashboard using Github actions with open source software and openly available (FAIR) data.
If we were lucky to travel to the Earth’s centre, perhaps as part of an international crew of terranauts chosen to observe and investigate our planet’s interior… just before entering the molten core, we would insist on making a “must stop” of our journey, almost like one of those vista points you can’t resist making a stop at, cruising along some imaginary coastal highway.
In these one-dimensional (1D) models, the Earth (or, as a matter of fact, any other planet) is divided into kilometres thick spherical layers, just like an onion on a much smaller scale
Australian earthquakes pose a high consequence – low likelihood risk that is widespread across the continent but is often not well characterised for some of Australia’s most important infrastructure.
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 .
