Map Monday 12: Geologic Map of Surtsey

With the news of a "new island" of formed by the Hunga Tonga-Hunga Ha’apai volcano in the south Pacific getting some attention in the geobloggosphere, I thought for this return to Map Monday, why not look back at another "recently created island". Surtsey is probably the most famous example of a undersea volcano reaching the surface. It has since become an important "natural experiment" of colonization of life.

The above image is a geologic map of Surtsey by the The Surtsey Research Society. The principle craters, vents, fissures are denoted by red lines. The purple colors shows various lavas, browns are tuff and tephra, and the tans are talus slopes and sand deposits.
