It wasn’t something that occurred to me in 2010. And it certainly didn’t until we drove off road today on our adventure. Along the area where there used to be a mountain top which exploded in lava and ash is now partly a plain criss crossed by flooded flat lands and rivers.
More than spew ash in the air to disrupt air traffic, volcanos produce heat. And if yours just happens to push lava up under the largest glacier in Iceland then the resulting large amount of melted ice should not be a surprise. Melted ice = water, right? Not just the planes then but also the local farmers flooded out, roads and bridges affected. Sheep, don’t forget the sheep. Really not sure how well they would swim in the month of April.
So there you have one of the second and third order effects; water run off and flooding. We managed to get 2/3 of the way toward the remaining glacial area before the height of the rivers made it too risky. No bridges here but off road in a 4×4
Instead we visited waterfall after waterfall one of which had a small climb (527 steps according to the sign) to reach the observation platform at the top. There is a really challenging hiking trail that starts there but we had neither the time or the equipment for a 26 km jaunt at this time of year.
Then there was the hiking behind a falls and the hiking up a river bed to the base of another. It was a fabulous day and hopefully I can do pix at some point.
