Better disaster prediction for South East Asia

By • August 14th, 2015

Southeast Asia is a tectonically active region that sees many natural disasters such as tsunamis and earthquakes occur as a result of these specific conditions. A team of researchers led by Dr Erdinc Saygin from the Australian National University is using the power of the Pawsey Supercomputing Centre to employ advanced imaging techniques that willmore…

GPU-based modelling, imaging and inversion of complex 3D/4D seismic wavefields

By • June 22nd, 2015

3D and time-lapse (4D) seismic imaging is central to the exploration for, and the monitoring of, hydrocarbon reservoirs and CO2 sequestration projects on WA’s Northwest Shelf.  The main imaging kernel involves modelling seismic waves through a 3D velocity model.  Generating usable seismic images requires repeating this modelling 1000s of times, necessitating the use of HPCmore…

Bayesian Lithological Inversion

By • June 22nd, 2015

Airborne electromagnetic (AEM) data are used in minerals exploration and to aid construction of groundwater models. Typically, these data are inverted using deterministic methods, for parameters of interest which must be interpreted for geological structure.  In contrast, our novel approach employs a stochastic methodology which attempts to invert directly for geologically-meaningful parameters and their uncertainties.more…
