Magnetic Etna 2025 (EMFC_2025)

The data represent the total intensity (F) of the Earth's magnetic field (or geomagnetic field) acquired continuously by the stations of the Etna permanent network from 01/01/2025 to 31/12/2025. All the stations are located along a South-North profile that crosses the summit area of ​​Etna and are equipped with Overhauser effect scalar magnetometers with a sensitivity of 0.01 nT. The network also includes a reference station located in Cesarò on the Nebrodi Mountains. The data are synchronized by a GPS and is acquired with a sampling rate of 5-10 seconds. Time series of geomagnetic data allow to observe and evaluate the anomalous variations of the magnetic field associated with the modifications of the stress field and of the thermodynamic state produced by magma rising in the more superficial layers of the volcano. The continuous data analysis therefore contributes to the evaluation of the spatio-temporal evolution of the dynamics in progress.
