Atlas of the Underworld | van der Meer, D.G., van Hinsbergen, D.J.J., and Spakman, W., 2017, Atlas of the Underworld: slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity, Tectonophysics
Subduction leaves a distinct geological record at the Earth’s surface, in the form of major mountain ranges such as the Andes or the Himalaya, or major volcanic arcs such as the Pacific Ring of Fire. Using these geological records, Earth Scientists have developed ways to determine when and where subduction episodes started and ended. On this website, we provide the current state-of-the-art of the images of slabs in the Earth’s upper and lower mantle, and the geological interpretation of when and where they were subducting. In the main article associated with this website, we use the information provided here to deduct physical properties of the mantle and slabs, and discuss ways to develop reference frames for plate reconstructions of the geological past. On this website, we provide open access to all slabs, organized by location, age, depth, and name.

Moving House
Issue #89

In the past quarter century, the world’s migration rate has doubled. Today, 232 million migrants live abroad, and 90 million more are currently packing their bags.

COLORS 89 – Moving House follows their journeys. While Spanish homeowners are setting up house on the streets after getting evicted from their homes, Chinese workers are moving into shipping containers in Shanghai. Indian temple devotees are sacrificing toy airplanes in return for a visa; halfway across the world, Mexican vacationists are voluntarily getting chased by fake US border patrol at a local tourist attraction. We’ve investigated people's motives to move, the borders they cross, the things they carry and the obstacles they surmount. Including a few tips on how to build a temporary shelter and a set of maps to put you on the right path, in case you are looking for one.

My Smartphone Died, and I Didn’t Miss It. Well, Maybe a Little.
Important point about how our global infrastructure expects us to have smartphones. Harder to live without them than it was before they came around, because we don’t have the same analog tools.

Exploring the Brutality of Expansion: Tracking Changes in the 19th Century with American Panorama - American Historical Association
Years ago, while preparing for a lecture, I ran across a GIF depicting the territorial expansion of the United States. While I am unsure of its origins, I’ve seen similar maps in textbooks, Wikipedia articles, and Google images. via Pocket

Bodleian Libraries - The oldest known road map of Britain
Drawn over two large pieces of sheepskin parchment, the truly remarkable Gough Map measures more than one metre wide and half a metre tall. Its size is impressive in person; even our slightly scaled-down facsimiles are a sight to behold.
Unlike most modern maps this one is oriented to the East - that is to say, North is situated to the left of this map if you put the have the text upright and readable.
