MAGMA Lab Facilities

Medusa Laboratory

Located in the Jane Herdman Building, the Medusa Laboratory is where we carry out all our laser-based experiments as part of our research into fluid dynamics, magma flow, and volcanic plumbing systems. Particle imaging velocimetry (PIV) and digital image correlation (DIC) are some of the techniques we use to examine magma flow regimes and deformation mechanisms and assess how these influence the eruption potential of underground magma.

PIV experiments are conducted using our Litron Nano TRL 325-15 PIV laser in conjunction with LaVision Imager SX Camera system and LaVision DaVis10 software for analogue modelling.

Medusa Preparation Laboratory

Adjacent to the Medusa Laboratory is a dedicated Medusa Preparation Laboratory which is fully equipped with the facilities to prepare analogue fluids and gels used for modelling in the Medusa Laboratory. Workbench spaces are also available for sample sorting and project activities.

**Gelatine preparation**

*Spacious area for preparing large tanks of gelatine*

The Volcanology Laboratory

Situated on the ground floor of the Jane Herdman Building, the Volcanology Laboratory is flexible space for non-laser based analogue experiments. It is a large room with dedicated areas for experiment set ups, group meetings and desk based activities. The space can accommodate groups for laboratory workshops and outreach events.

Rheometry

Our TR Instruments HR20 Rheometer is used to test the rheological properties of fluids used within our research experiments. The rheometer uses the latest TRIOS™ software for rheological data analysis.

Numerical Modelling, Drones, Photogrammetry & Virtual Reality

The lab is equipped with dedicated workstations for data processing and analysis.

We have the facilities for photogrammetry using Agisoft Metashape 3D imaging software to process images collected during fieldwork using our DJI mini2 or DJI Mavic 3pro drones. 3D mapping images of field study areas can be created and used in conjunction with our virtual reality 3D headset.

The Volcanology Laboratory also has a dedicated workstation for operating COMSOL Multiphysics® software for Structural Geology, Fluid Flow and Heat Transfer modelling.
