Connie - there is a definite cycle. This current volcano, Grímsvötn, was very active in the 19th century and the first decade of the 20th but then there was little activity with only a few very small eruption for most of the century. Activity started again in 1998 and this is the third eruption since then so experts predict that this is the start of another "active" cycle for eruptions in Grímsvötn. Hekla has erupted on average about twice a century since the 12th century .... but since 1970 she's erupted like clockwork once a decade (1970, 1980, 1991 and 2000) .... according to that pattern she should have erupted last year .... or this year and judging from magma movements she will erupt in the very near future. People have been warned against hiking up the mountain for the past two years since an eruption there could start with little warning. She's ready to blow at any time basically. And Katla has also been pretty "regular" erupting 1-2 times a century. It's been a rather long interval since her last eruption in 1918 so she's also "due" ...... so all of these are pretty much "scheduled" eruptions .... and nothing out of the ordinary. Big Grin
