ASEG WA Tech Night: Geologically constrained level-set inversion with null-space analysis for evaluation: application in the Western Pyrenees.

Thursday, March 2, 2023

Title: Geologically constrained level-set inversion with null-space analysis for evaluation: application in the Western Pyrenees.

Presenter: Jeremie Giraud

Date: 02/03/2023

Time: 1730-1900

Location: The Shoe Bar and Cafe 376 - 420 Wellington Street Perth, WA 6050




We present and apply an algorithm integrating automated geological modelling into geometrical gravity inversion. The method we employ is based on a generalized, iterative level-set inversion scheme where geological units are deformed automatically to fit geophysical data. The proposed approach is formulated to account for geological data and principles during geophysical inversion. This is achieved by incorporating an automated geological modelling scheme in the regularization term of the geophysical inverse problem’s cost function. The geological modelling term provides model-dependent geological constraints and encourages geological realism during inversion. After summarizing the method that we employ, we present a field application where we refine a pre-existing 3D geological model which is locally inconsistent with geophysical data. The objective of this application case is to automatically resolve this inconsistency by improving geophysical data fit (i.e., the Bouguer anomaly) in selected areas while maintaining consistency with some geological observations (e.g., contact locations, orientation data) and principles (e.g., are relationships, structural rules). We consider a subduction zone generated during the Iberian and Eurasian intraplate collision with a partial uplift of the upper mantle located in the Western Pyrenees Mountain range across France and Spain. We focus on the structure of the upper crust and investigate the presence of abnormally dense material. We also use our algorithm to explore alternative geological scenarios and assess their consistency with geophysical data using the concept of 'null-space shuttle' to derive geophysically equivalent models.

AuScope Special Seminar with ChEESE Program Leader Prof Arnau Folch

Monday, February 6, 2023
1200 AEDT
1330 AEDT

HPC is increasingly being used in solid Earth Geophysics in Europe and AuScope has organised this Special Seminar with Arnau Folch, leader of the EU ChEESE Program

ChEESE is the EU Centre of Excellence for Exascale in Solid Earth and develops translational research capabilities in High Performance Computing to the Exascale in geophysics, enabling multiscale, multiphysics and multi-hazard analysis.

In this seminar, Arnau will present the results of ChEESE-1P Exascale Pilot Demonstrators, including:

·  Rapid probabilistic forecasts of tsunami inundations; 

·  Earthquake source prediction; and

·  The atmospheric volcanic ash dispersal models validated in real time against high-resolution geostationary satellite data.

And, introduce ChEESE-2P and highlight its role in an ecosystem of projects that are shaping Europe’s Digital Future, including:

·  A Digital Twin for GEOphysical Extremes (DT-GEO);

·  Destination Earth (DestinE); and 

·  European Plate Observing System (EPOS)

Date: February 6th from 12 pm to 1:30 pm AEST.

Please register here via Eventbrite.



The first phase (ChEESE-1P) ran from 2018-2022 and addressed scientific and technical computational challenges in moving existing systems to Exascale in seismology, tsunami science, volcanology, and magnetohydrodynamics. ChEESE-1P initiated the optimisation of 10 Community flagship European codes for the European pre-Exascale and Exascale supercomputers and developed 12 Pilot Demonstrators (PD) that enabled services oriented to critical aspects of geohazards, including hazard assessment, urgent computing, and early warning forecasting.

Following the success of ChEESE-1P, a second 4-year phase (ChEESE-2P) with funding of € 7.8 million was launched in January 2023. Arnau will lead a team of Earth and Computer Scientists across multiple programs that will further develop the ChEESE-1P codes and new codes in geodynamics and glaciology.

We are delighted to be hosting Arnau and welcome you to join us in what will surely be a great seminar.
