Aerial Photographs Catalogue the Life and Death of Volcanic Islands

Aerial Photographs Catalogue the Life and Death of Volcanic Islands | Geography in the classroom | Scoop.it

Volcanic islands can seem to appear out of nowhere, emerging from the ocean like breaching monsters of the deep. Below, Mika McKinnon explains how these odd geological formations are born, how they evolve, and how they eventually vanish back beneath the waves.

Matthew Richmond's curator insight, December 2, 2015 3:30 PM

Re-scooped from Professor Dixon, pretty cool story on the formation of islands in the south Pacific. A couple of them look like the island visible from the beach in Rincon, Puerto Rico where I stayed. The island is one giant rock so nobody lives there and it's a naval base for the U.S. military. This, however, is a different situation when you realize that not only do people live here, but kind of a lot of people live here.

What causes the death and the caldera in a volcano? One thing that happens in a deceased volcano is the center of the volcano starts to either erode or the inside finally caves in. Once this happen a caldera takes shape and the ocean starts to take over. As the waves eat away at the shores it will eventually create a island that is shaped like a "U". After this happens that island will someday retreat back into the ocean and someday form a barrier reef.

Adam Deneault's curator insight, December 14, 2015 10:52 PM

Based on general knowledge, I know that the taller a volcano is, the younger it is and the shorter it is, the older it is. The reason they start to get short is from erosion. Hot spots in the Earth's crust make small islands from molten rock. Young islands can be very dangerous, because if they are inhabited, they have the possibility of erupting, whereas an old island does not since the volcano is lnactice and eroding. Over time the inactive volcano will crumble and a caldera will take shape and after even more time, that caldera will slip under the ocean and become a reef.

Melting Glaciers Transform Alpine Landscape

Climate change is dramatically altering the Swiss Alps, where hundreds of bodies of water are being created by melting glaciers. Though the lakes can attract tourists and even generate electricity, local residents also fear catastrophic tidal waves.
