Exploring links between physical and probabilistic models of volcanic eruptions: The Soufrière Hills Volcano, Montserrat
[1] Probabilistic methods play an increasingly important role in volcanic hazards forecasts. Here we show that a probability distribution characterized by competing processes provides an excellent statistical fit (>99% confidence) to repose intervals between 75 vulcanian explosions of Soufrière Hills Volcano, Montserrat in September–October, 1997. The excellent fit is explained by a physical mo...
متن کاملThe bioreactivity of the sub-10 μm component of volcanic ash: Soufrière Hills volcano, Montserrat.
With the recent eruption of the Icelandic volcano Eyafallajökull and resulting ash cloud over much of Europe there was considerable concern about possible respiratory hazards. Volcanic ash can contain minerals that are known human respiratory health hazards such as cristobalite. Short-term ash exposures can cause skin sores, respiratory and ocular irritations and exacerbation of pre-existing lu...
متن کاملLong range transport and fate of a stratospheric volcanic cloud from Soufriere Hills volcano, Montserrat
Volcanic eruptions emit gases, ash particles and hydrometeors into the atmosphere, occasionally reaching heights of 20 km or more, to reside in the stratospheric overworld where they affect the radiative balance of the atmosphere and the Earth’s climate. Here we use satellite measurements and a Lagrangian particle dispersion model to determine the mass loadings, vertical penetration, horizontal...
متن کاملProbabilistic analysis of rockfall frequencies during an andesite lava dome eruption: The Soufrière Hills Volcano, Montserrat
[1] A probabilistic analysis of rockfalls has been undertaken using seismometer-determined information on the timing and duration of rockfalls from the Soufrière Hills lava dome, Montserrat, between 1995 and 1997. Repose intervals between rockfalls fit log logistic survivor distributions. Differences in the log logistic survivor function for different sub-sets of data are accommodated by variat...
متن کاملPastoral Care in Disaster: Lessons from the Montserrat Volcanic Eruptions
The research explores three interrelated theological problems – human suffering as encountered during the eruptions of the Soufrière Hills Volcano on Montserrat, the inadequacy of existing Protestant religious traditions on Montserrat to cope with the crisis situation, and the weaknesses of recommended models of pastoral care inherited from Western Christianity. The latter two concerns became o...
