Geophysics Victorian Earthquake Round-up 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.
Seismology Australia surprised by moderate quake, but rumbling is not unusual 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.
Geohazards How earthquake science supports decision-making in the ancient continent 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.
Geodynamics Geodynamic models link enigmatic intraplate volcanism in Eastern Asia to subduction history and upper mantle upwellings In Eastern Asia, Jurassic and Cretaceous intraplate volcanism and magmatism differ in their spatial distribution and composition. A combination of plate kinematic and geodynamic models provides clues for their causes.
Geophysics Chatting about reconstructing 1 billion years of Earth evolution in Geology Bites podcast This is a transcript of a podcast with Oliver Strimpel from GeologyBites. We chat about the challenges and benefits of reconstructing Earth evolution over a billion years.
Tectonics Modelling global precipitation since 250 million years ago We have developed a novel data-driven approach to reconstruct precipitation patterns through geological time, since the supercontinent Pangea was in existence. Our approach involves linking climate-sensitive sedimentary deposits such as
Geodynamics The Earth's troubled childhood Continents host the oldest building blocks of the Earth's surface and keep a record of the processes that shaped it. A careful reading and high-performance computational modelling of the early, hotter Earth reveal a coming of age story.
Geodynamics On the destructive tendencies of cratons Katie Cooper, Rebecca Farrington and Meghan Miller explain how cratonic lithosphere can be sculpted by flow from a passing subducting slab.
Tectonics How Earth's continents became twisted and contorted over millions of years Figure: Photographed on Kangaroo Island, this rock – called a ‘zebra schist’ – deformed from flat-lying marine sediments through being stressed by a continental collision over 500 million years ago. Dietmar Muller
Geophysics Rocky icebergs and deep anchors – new research on how planetary forces shape the Earth’s surface A recent article in The Conversation by Simon Lamb from Victoria University of Wellington "uncovers the fundamental forces that control the Earth’s surface". They use Crust 1.0, ETOPO1, and the McKenzie and Priestley lithosphere model to compute their "Whole Layer Isostasy" model.
