Multifractality in local geomagnetic field at Etna volcano, Sicily
We applied the Multifractal Detrended Fluctuation Analysis (MF-DFA), which allows to detect multifractality in nonstationary signals, to the hourly means of local geomagnetic field recorded at Mt. Etna volcano (southern Italy). We studied the signal measured at one geomagnetic station, installed at the summit of volcano, which was characterized by a strong eruption on 27 October 2002. We analyz...
متن کاملFlank instability at Mt. Etna
Due to their constant and relatively rapid growth, volcanic edifices are inherently unstable. Flank instability is observed at many polygenetic stratovolcanoes, composite volcanoes and shield volcanoes worldwide. Flank instability may occur suddenly, or develop in a more continuous and subtle way, accelerated by triggering events (magma emplacement, eruptions and earthquakes). Destabilization i...

متن کاملImproved Estimates of Kinematic Wave Parameters for Circular Channels
The momentum equation in the kinematic wave model is a power-law equation with two parameters. These parameters, which relate the discharge to the flow area, are commonly derived using Manning’s equation. In general, the values of these parameters depend on the flow depth except for some special cross sections. In this paper, improved estimates of the kinematic wave parameters for circular chan...
متن کاملA statistical analysis of eruptive activity on Mount Etna, Sicily
S U M M A R Y A rigorous analysis of the timing and location of flank eruptions of Mount Etna on Sicily is important for the creation of hazard maps of the densely populated area surrounding the volcano. In this paper, we analyse the temporal, volumetric and spatial data on eruptive activity on Etna. Our analyses are based on the two most recent and robust historical data catalogues of flank er...
