Where do we see the future of analogue modelling? Which are the main challenges we have to face to continue producing useful results for the scientific community?

With these fundamental questions in mind we initiate the first methodological workshop for tectonic and volcanological experimental modelers. The current 2-day workshop focuses on visual (kinematic) monitoring with two oral sessions on that topic. The poster sessions are open to any methodological contribution. The workshop is followed by a short course on "displacement fields and deformation".

1st Workshop on Advances in Quantitative Analogue Modeling (AiQAM):

Quantitative deformation analysis in analogue tectonic and volcanic models. Exploring particle image velocimetry (PIV) and other methods for high resolution displacement monitoring.

In the past decade, digital image analysis methods such as PIV (Particle Image Velocimetry, derived from fluid physics) have found their way into experimental modeling of tectonic and volcanic processes. The availability of accurate and precise constraints on the kinematic evolution of the models at high spatiotemporal resolution has a number of advantages. Firstly, it allows a more quantitative analysis of the models and thereby physical interpretation of the system under consideration. Moreover, it allows for better integration of experimental results with geodetically observed natural systems and numerical models, which rapidly evolve into the 4th dimension (3D space and time) due to increased computational power. This integration potentially allows for more reliable benchmarking and/or the development of hybrid approaches, which will provide better understanding of the mechanics of the modeled system.

This workshop firstly aims to facilitate the exchange of experience on the different methods (such as particle image & tracking velocimetry, Moiré projection, photogrammetry), softwares (in case of PIV, from commercial LaVision DaVis to Matlab toolboxes such as MatPIV and PIVlab) and post-processing toolboxes (e.g. PIVmat, SSPX) for extracting quantitative information on displacement and strain from the models. Secondly, by connecting a critical mass of researchers working on these methodologies, it aims to enhance method development and promote its dissemination also on the longer term.

Invited speakers will share their experience on these methods in two sessions, “monitoring methods” and “post-processing for quantitative deformation analysis”. In addition, we call for poster contributions to the workshop, highlighting any methodological advances in your experimental work, including but not limited to monitoring and image analysis. The workshop is followed by a short course on displacement fields and deformation.

We look forward to welcoming you in Potsdam!
