Eruptions of Mt. Etna during the past 3,200 years: A revised compilation integrating the historical and stratigraphic records

摘要: A critical re-examination of the original chronicles and previously published summaries Etnean activity, within context recently available stratigraphic, mapping, radiometric data, has made possible a detailed reconstruction Etna's historical eruptions during past three millennia. Our compilation, updated to 2002 flank eruptions, lists only those events for which both age corresponding deposit are known, thereby eliminating inaccurate, uncertain, or poorly located volcanic contained in previous compilations. Not surprisingly, discrepancies between stratigraphic databases were noted before 1600 AD, after which, however, two good agreement. By excluding questionable our compilation necessarily underestimated number pre-1600 events, when compared with that determined from sources. study indicates that, period 1975, eruption frequency lava output Etna relatively uniform; since these parameters increased markedly. To understand significance implications this activity 1975-2000, more complete prehistoric eruptive history will be essential.
