Many of the grand challenges in volcanic and magmatic research are focused on understanding the dynamics of highly heterogeneous systems and the critical conditions that enable magmas to move or eruptions to initiate. However, we are usually unable to observe the processes directly. Here we give a short synopsis of the new capabilities and highlight the potential insights that in situ observation can provide. We present the first 3D data showing the evolving textural heterogeneity within a shearing magma, highlighting the dynamic changes to microstructure that occur from the initiation of shear, and the variability of the microstructural response to that shear as deformation progresses.

How Amira-Avizo Software is used

All data have been visualized and processed in Avizo© 2019.2. The data shown have received minimal post processing. Data have been cropped, down sampled and filtered […] To interpret the displacement field within the melt, this rigid body motion was removed using the Registration algorithm in Avizo, prior to running a DVC analysis. […] The local-global integrated Avizo DVC approach showing how the outputs from one iteration and scale can be used to initiate the calculation at the next spatial or temporal step.
