Réunion Island

This is a rerun of a post that appeared in December, 2013: the date explains the unseasonal greeting at the start. It was written by Fran. Reunion sits near the head of a chain of volcanic islands in the Indian Ocean, ending (or beginning) at the Deccan traps. Hot spot volcano candy at its best.)…

The forgotten volcanoes of Chad Part II

In the previous part I wrote that we would be investigating some of the largest sub-aerial volcanism on the planet as we took a closer look at this the largest known sub-aerial volcanic system in the world. And now it is time to look at volcanism on a stupendous scale. But before we do that…
