Have you ever wondered what is? Or how long the journey to the centre takes?

In what has been described as a 80 year holy grail mission, scientists or more specifically seismologists discovered what lies in the epicentre of Earth.

Professor Hrvoje Tkalčić head of Geophysics at ANU and Lauren Wasze, a global seismologist at James Cook University speak to Suzanne Hill about the inner layers of planet Earth.

Professor Meghan S. Miller talks about her research into critical tectonic plate boundaries, in particular, subduction zones where oceanic plates are descending into the Earth’s deep interior (e.g. Indonesia, Alaska, Japan, Italy). Her research asks questions such as, How has the outermost layer of the Earth evolved? How do processes and structures deep within the Earth control the geology we can observe at the surface?

University of Sydney researchers have identified a groundwater ‘superhighway’ along Australia’s east coast. Stretching from Canberra to Brisbane, the flow of water connects aquifers (underground layers of water-bearing permeable rock) that stretch for thousands of kilometres.

University of Sydney scientists have used the geological record of the deep sea to discover that past global warming has sped up deep ocean circulation. This is one of the missing links for predicting how future climate change may affect heat and carbon capture by the oceans.

Victoria hosts arguably Australia’s most sophisticated seismic network for detecting and mapping earthquakes. But why does Australia need earthquake mapping?

A high precision seismic network is now able to detect about 400 earthquakes every year in Victoria’s Gippsland region, providing key information to protect people and infrastructure

Geoscience Australia has released an electrical conductivity model for northern Australia, enabling a deeper understanding of mineral compositions hundreds of kilometres below the surface.

Brutal university cuts are putting at risk an industry crucial to addressing climate change Down Under and around the world. Saving geoscience will require a community reckoning.

In a paper published today in Nature Human Behaviour, researchers from The University of Melbourne and The University of Western Australia use a pioneering, AuScope enabled radiocarbon dating technique to date the artwork as being between 17,500 and 17,100 years old — making it Australia’s oldest known in-situ rock painting.
