Researchers from the Earth Science Institute went to Tenerife in June 2016 to carry out volcano-gravimetric field work. The objective of the observation campaign was to measure in-situ vertical gradients of gravity (VGGs) for the sake of verifying the numerically predicted (modelled) extreme values of the VGG. The crew comprised Peter Vajda and Pavol Zahorec of the Department of Gravimetry and Geodynamics of our institute, as well as Juraj Papčo of the Department of Geodesy of the Slovak Technical University in Bratislava. The campaign span one week (20–28 June, 2016). This field work campaign was conducted successfully and the acquired data seem promising.


Measurable temporal changes of gravity and deformations of earth's surface are indicators of dynamic processes inside the earth, such as those associated with movements of magma preceding volcanic eruptions. The observation, analysis and interpretation of surface gravity changes and vertical displacements of the topographic surface contribute to understanding the physics of magma reservoirs and the processes associated with volcanic activity.
