- Abstract
- Long-range dispersal of volcanic ash can disrupt
civil aviation over large areas, as occurred during the 2010
eruption of Eyjafjallajökull volcano in Iceland. Here we assess
the hazard for civil aviation posed by volcanic ash from a
potential violent Strombolian eruption of Somma-Vesuvius,
the most likely scenario if eruptive activity resumed at this
volcano. A Somma-Vesuvius eruption is of concern for two
main reasons: (1) there is a high probability (38 %) that the
eruption will be violent Strombolian, as this activity has been
common in the most recent period of activity (between AD
1631 and 1944); and (2) violent Strombolian eruptions typically
last longer than higher-magnitude events (from 3 to 7 days for
the climactic phases) and, consequently, are likely to cause
prolonged air traffic disruption (even at large distances if a
substantial amount of fine ash is produced such as is typical
during Vesuvius eruptions). We compute probabilistic hazard
maps for airborne ash concentration at relevant flight levels
using the FALL3D ash dispersal model and a statistically
representative set of meteorological conditions. Probabilistic
hazard maps are computed for two different ash concentration
thresholds, 2 and 0.2 mg/m
3
, which correspond, respectively, to
the no-fly and enhanced procedure conditions defined in
Europe during the Eyjafjallajökull eruption. The seasonal influence of ash dispersal is also analysed by computing seasonal
maps. We define the persistence of ash in the atmosphere as the
time that a concentration threshold is exceeded divided by the
total duration of the eruption (here the eruption phase producing
a sustained eruption column). The maps of averaged persistence
give additional information on the expected duration of the
conditions leading to flight disruption at a given location. We
assess the impact that a violent Strombolian eruption would
have on the main airports and aerial corridors of the Central
Mediterranean area, and this assessment can help those who
devise procedures to minimise the impact of these long-lasting
low-intensity volcanic events on civil aviation. (literal)
