ERS InSAR Observations of Mt. Etna volcano: Magma inflation and radial spreading
We present a synthesis of ERS-1 and ERS-2 differential SAR interferometry (InSAR) observations of Mt. Etna volcano over roughly the past ten years from 10022002. Through this time period Mount Etna underwent a cycle of eruptive activity starting with a large flank eruption that ended in March 1993, followed by two years quiescence, with resumed summit activity starting in the summer of 1995, cu...
متن کاملRe-Os ISOTOPIC AND HIGHLY SIDEOPHILE ELEMENT SYSTEMATICS OF PALLASITES
Introduction: Pallasites are of great interest to meteoriticists because they may represent samples of the interfaces between core and mantle materials in asteroids. Further, certain pallasites may be genetically related to the group IIIAB irons, based on similar ∆O values [1], potentially permitting the study of core-mantle evolution within a single body. To better understand the origin and ev...

متن کاملOxygen Isotopic Variations in the Clinopyroxene from the Filicudi Volcanic Rocks (Aeolian Islands, Italy): Implications for Open-System Magma Evolution
Oxygen isotope data are reported for clinopyroxene phenocrysts from volcanic rock samples from Filicudi island, Italy, with the aim of investigating mechanisms of magma evolution and mantle source characteristics in a continental arc volcano. Filicudi rocks range from calc-alkaline basalt to high-K andesite and dacite. Mafic rocks have MgO 6-7 wt%, Mg# 60, Ni < 50 ppm and Cr < 200 ppm, suggesti...
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...
