Volcanoes are just one of the most spectacular pieces of evidence of how the earth is constantly active. It is one area where the speed of change is much faster than the processes of mountain building, or the centimetre-by-centimeter spreading of ocean floors. This learning pathway looks in detail at a number of different active volcanoes around the world, from the Mediterranean island of Santorini, the site of the largest eruption in recorded history, to Iceland that continues to grow out of the North Atlantic, and Pinatubo in the Philippines. It looks at different eruptive styles, including flood basalts with a visit to the spectacular Columbia River plateau basalt which covers around 160,000 square kilometers of Washington State and Oregon, to a depth of around 1.8 km.

The pathway includes a visit to the site of a sixty million year old eruption in Northern Ireland. This video rich step provides valuable lessons in how to interpret a geological exposure. At the same time it offers a visit to the Giant’s Causeway, a UNESCO world heritage site, and a featured part of the exposure. The pathway starts by setting volcanoes into the world context with an exploration of the structure of the earth and the theory of plate tectonics, explaining where volcanoes are found, and why they are found there.
