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.
Buoyant material rising in the Earth's mantle is expected to spread out when it reaches the base of a tectonic plate like pancake batter dropped into a pan.
The Australian Air Force flew 100 years of aircraft through the centre of Canberra on March 31st and we recorded their seismic signal from the Parliament House Basement
Integration of passive seismic images, geochemistry, and reconstruction of uplift from river profiles provide new findings on arc-continent collisional processes
The dominant variation of the physical properties of the Earth is with depth, though complex 3-D structures are present in the top 1000 km and near the core-mantle boundary.
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?
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.
Unlike Sirens, who drew sailors to the rocks by their enchanted singing, causing their ships to sink, Nereids – the daughters of Doris and Nereus, the old man of the sea – were helping sailors through rough seas.
When you are pressed for time, the only thing you hope for is for things to go as smoothly as possible so that you can move on.
The Earth’s crust is made up of tectonic plates that are constantly in motion. Large, destructive earthquakes occur when accumulated energy at plate boundaries - where two plates are pushing against each other - is suddenly released.
