Eruptions of volcanoes in Iceland: Katla and Eyjafjallojokull P.M.E.Altham, University of Cambridge.
 

Summary: Eruptions of volcanoes in Iceland: Katla and Eyjafjallojšokull
P.M.E.Altham, University of Cambridge.
May 4, 2010
The following data on the `Eruptions of the Katla volcanic centre in historical times' was
published by G.Larsen in 1993: see
www.earthice.hi.is
This gives the Duration of the eruption in days, and the Repose time in years: the latter being the
time since the previous eruption. Some readings are only approximate, and are correspondingly
marked, for example
~120
The Duration times are not known for eruptions before 1625.
What can you make of this dataset? For example, you might like to try
library(MASS)
fitdistr(Duration, ...)
The next Katla eruption was predicted to be before 2010 (see for example the 2007 Lonely Planet
Guidebook to Iceland). Comment.
Does the Duration of an eruption increase as the corresponding ReposeTime increases? (We haven't
really got enough data to tell?)
Year Duration ReposeTime
1918 24 58
