What’s up with Iceland? Hekla Edition

This article on Hekla is my personal birthday gift to Mike Ross on his big day. Congratulations Mike! About once a year I write a piece about which five Icelandic volcanoes would be the most likely to erupt given the signals they have fired off during the last year. This list normally contains roughly the…

In the case of Hekla there is also available mountain strain data from borehole strainmeters. For some volcanoes there are also periodic gas measurements taken and…
