Where is it, and why is it a place of interest for geologists?

The Marquesas Archipelago is geographically notable for really being one of the most remote places on Earth.

It's roughly in the southwest Pacific Ocean, but the nearest recognizable island of any extent would be Tahiti, and that's just shy of 1,500 kilometers away.

It's what we call a volcanic hotspot.

Best known ones would be Hawaii or Iceland or the Galapagos.

So in the east, the island of Fatuhiva is the youngest volcanism on land.

It's about one and a half million years old.
