Description:
Quiescent volcanoes dissipate a large part of their thermal energy through hot soils and
ground degassing mainly in restricted areas called Diffuse Degassing Structures. La Solfatara crater
represents the main spot of thermal release for the Campi Flegrei volcano (Italy) despite its reduced
dimensions with regards to the whole caldera. The purpose of this study was to develop a method
to measure thermal energy release extrapolating it from the ground surface temperature. We used
imaging from thermal cameras at short distances (1 m) to obtain a mapping of areas with thermal
anomalies and a measure of their temperatures. We built a conceptual model of the energy release
from the ground to atmosphere, which well fits the experimental data taken in the La Solfatara crater.
Using our model and data, we could estimate the average heat flux in a portion of the crater as
qavg = 220 40W/m2, compatible with other measurements in literature.
