Field Activity 2025-602-FA

Identifier 2025-602-FA
Alternate names Santorini
Purpose To quantify the interactions between hydrothermal and magmatic systems in dormant and active phases in order to forecast the role fluids play in explosive caldera eruptions. The main objectives are to determine the controls on permeability pathways and fluid flow within calderas, identify the role the hydrothermal system plays in magmatic outgassing, and to assess hydrothermal system response to periods of intrusion.
Location Mediterranean Sea
Info derived Short-lived radium isotope (Ra-223 & Ra-224) concentrations in hydrothermal plume water and hydrothermal oxide minerology and geochemistry data.
