Hekla is not necessarily a nasty surprise waiting to happen. It goes off every 10 to 16 years, or so. However, both it and the rest of Iceland sit on
the Atlantic spread zone. With the canary islands heating up, and Iceland heating up, I wonder what other volcanoes might soon be showing activity?
Time for some research, me thinks.
I'm working my way up the Atlantic, from the south. Helicorders are thus far difficult to find for Tristan de Cuma and Nightengale Island, but I'm
continuing to look. If Tristan de Cum was heating up, that would be something significant when taken alongside the other activity along the zone.
From what I can see, Fogo would be the next logical step (if we ignore the reported volcanoes along the mid-atlantic ridge which have never been
verified). Fogo has had venting in the past, which makes it a possible candidate.
To understand exactly how the mid-atlantic ridge, a spread-zone for the expanding Atlantic ocean, runs up the Atlantic, go to this page and select a
long rectangle that runs south from Iceland to Antarctica. You'll see all of the earthquake activity for the past year or so along the ridge. It
will show you nicely how this is evolving.
