Overview

Studying fundamental volcano‐magmatic processes is difficult because volcanic systems are complex non‐linear systems, which makes each volcano unique. Volcanic eruptions occur when magma reaches the surface. Magma migration from depth up through the brittle crust occurs by the propagation of hydraulic fractures or dykes. Dyke propagation involves complex physic processes such as viscous flow of magma, rock fracture, elastic deformation of the host rock, and potentially large changes of the physical properties of the magma (crystallization, degassing, solidification, etc).

This research involves the use of seismic data to track magma motion within the crust; analysing the seismicity generated by magma transport is one way to image this phenomenon. A physical model that quantitatively relates the flux of magma in the dyke to real-time geophysical data is lacking. Numerical and analogue models will therefore improve our understanding of the parameters that govern the intrusions of magma.

Some less traditional methods will also be implemented to unravel the volcano-magmatic processes, like muon tomography or the study of corals around volcanic systems. These innovative approaches will help us understand the processes at stake in the magma transport at depth and in the shallower parts of the volcanic edifice.

The purpose of the Lab Volcanoes is to understand the timing, rates and other details of the magma supply of different volcanoes, in order to improve forecasts of future eruptions. To this end, laboratory volcanoes display very diverse monitoring tools that provide a constant flow of data.


EOS has developed volcano laboratories at Mayon (Southeast Luzon, Philippines) and Gede-Salak (West Java, Indonesia). These volcanoes span a wide range of degassing behaviours: Mayon is an openly degassing volcano, while Gede and Salak exhibit only minor degassing. The nuances on the degassing spectrum displayed by these volcanoes make them very valuable for fundamental research.
