Abstract Satellite observations have enabled an important advance in the near‐real‐time quantification of the dynamic parameters of the volcanic plume spreading in the atmosphere. However, the link between these observations and the estimation of eruption source parameters, such as the mass eruption rate (MER), remains a scientific obstacle to be ...

Abstract The Sinus Aestuum (SA) dark mantle deposit (DMD) is a regional pyroclastic deposit on the central lunar near‐side. Spectra from the SA DMD are anomalous when compared to other DMDs and have been interpreted to represent a high abundance of the mineral spinel. The SA spinels are compositionally distinct compared to other lunar spinels and their

Changes in SO2 Flux Regime at Mt. Etna Captured by Automatically Processed Ultraviolet Camera Data
We used a one-year long SO2 flux record, which was obtained using a novel algorithm for real-time automatic processing of ultraviolet (UV) camera data, to characterize changes in degassing dynamics at the Mt. Etna volcano in 2016. These SO2 flux records,

Trigger mechanism and propagation dynamics of pyroclastic density currents at basaltic volcanoes
Pyroclastic density currents (PDCs) are among the deadliest manifestations of volcanic eruptions, commonly associated with volcanoes characterized by intermediate to felsic magma compositions and related to eruption column collapse, lateral blasts, or ...

The HOTSAT volcano monitoring system based on combined use of SEVIRI and MODIS multispectral data
Spaceborne remote sensing of high-temperature volcanic features offers an excellent opportunity to monitor the onset and development of new eruptive activity. To provide a basis for real-time response during eruptive events, we designed and developed the

In September 2016, Piton de la Fournaise volcano, well known for its effusive and Hawaiian fountaining activity, produced, at the end of the eruption, an unusual phase of pulsating ash and bomb emission. Integration of geophysical data, with textural and

AbstractWe present the analysis of ~4 million infrasonic signals which include 39 episodes of lava fountains recorded at 5.5 km from the active vents. We show that each eruptive episode is characterized by a distinctive trend in the amplitude, waveform, and frequency content of the acoustic signals, reflecting different explosive levels.

Volcanic SO2 by UV-TIR satellite retrievals: validation by using ground-based network at Mt. Etna
Mt. Etna volcano in Italy is one of the most active degassing volcanoes worldwide, emitting a mean of 1.7 Mt/year of Sulphur Dioxide (SO2) in quiescent periods.
