Geological map of Etna volcano, 1:50,000 scale

, 2011
The new geological map of Etna volcano at 1:50,000 scale represents a significant progress in the geological studies of this volcano over the last 30 years, coming after Waltershausen’s map published around the mid of 19th century, the first ...

Reawakening of Voragine, the Oldest of Etna’s Summit Craters: Insights from a Recurrent Episodic Eruptive Behavior

Remote Sensing
Paroxysmal explosive activity at Etna volcano (Italy) has become quite frequent over the last three decades, raising concerns with the civil protection authorities due to its significant impact on the local population, infrastructures, viability and air ...

Double-difference tomography at Mt. Etna volcano

, 2007
Double-difference tomography at Mt Etna volcano was realized by using the tomographic algorithm developped by Monteiller et al. (2005), in which the travel-time computation was performed using a finite-difference solution of the Eikonal equation ...

Insights into the internal dynamics of Etna volcano through discrete and continuous microgravity observations

, 2006
Discrete and continuous microgravity observations have been routinely performed at Mt. Etna since 1986 and 1998, respectively. Besides furnishing a full view of how gravity measurements from Etna are accomplished and reduced, this paper is a collection

Radioactivity of Mt. Etna volcano and radionuclides transfer to groundwater

, 2019
The paper presents the results of a radiometric survey carried out on the eastern flank of Mt. Etna over an area of approximately 120 km2. Activity concentrations of 238,234U, 232,230,228Th, 226,228Ra, from 238U and 232Th decay chains, and potassium 40K were determined using α- and γ- spectrometry techniques.

ABSOLUTE AND RELATIVE GRAVITY MEASUREMENTS AT ETNA VOLCANO (ITALY)

, 2011
Employing both absolute and relative gravimeters, we carried out three hybrid microgravity surveys at Etna volcano between 2007 and 2009. The repeated measurements highlighted the spatio-time evolution of the gravity field associated with the volcanic ...

Magnetic Field Monitoring at Mt. Etna During the Last 20 Years

, 2004
Over the past few decades we have been intensively monitoring the magnetic field on Mt. Etna. The largest anomaly, about 10 nT, was observed in the geo-magnetic time series recorded in 1981 and associated with the March 17-23 eruption.
