Biography

Pablo J. González is a Senior Researcher in Geodynamics and Structure of the Lithosphere, at the Volcanological Research Group. Department of Life and Earth Sciences (IPNA-CSIC) located in La Laguna, Tenerife, Canary Islands.

We study volcano and fault mechanics, or in simple terms, how and why volcanoes and faults deform. A knowledge with practical application for geological hazard assessment, and risk reduction. To learn more about magmatic sytems and fault zone processes we use constrains from geophysical and geodetic observations, mainly Earth Observation data. Our ultimate goal is to gain insights into the physical behaviour of volcanoes and fault systems to incorporate into models with ever increasing predictive power.

Research interests

• Magma storage and migration at volcanoes
• Fault dynamics and kinematics, including volcano-tectonics
• Fluid-rock mechanical interactions (Induced seismicity, groundwater changes)
• Geodetic and geophysical techniques: data processing and analysis
• Geophysical inverse problems (Bayesian inference)
• Machine Learning (Reduce Order Models and Deep Learning)

Current team members:

• Pablo J. González (Senior Researcher)
• Yu Jiang (COMET and University of Liverpool PhD researcher funded by CSC China Scholarship, 2017-2021). Yu works on the mechanics of continental normal faults applying satellite geodesy and bayesian inference methods.

In addition, we have enjoyed working with our lab visitors, and past team members.

Work with us:

The Estación Volcanológica de Canarias is a research group within CSIC, Spain’s largest research-intensive institution. CSIC is not an academic institution and does not award PhD degrees. However, we are able to supervise, e.g., early career researchers a) who are enrolled in Environmental and Earth Sciences PhD programs at Spanish universities, b) postdoctoral researchers (Marie Curie, Juan de la Cierva, etc), or c) otherwise self-funded researchers who want to spend time in Tenerife for a time-limited project.

If you are interested to collaborate, please contact me and come to research in Tenerife.
