What’s up? The Friday links (44)

Today’s Friday links are mostly about cake geology and scientists playing with food, but let’s start with something different. Yesterday, volcano Fuego (“fire”) erupted in Guatemala and produced an impressive column of ash and smoke. This beautiful stratovolcano is only 40 km from Guatemala City and one of the most active volcanos of Central America.


Blend scenes from San Francisco after the 1906 earthquake and today

Photographer Shawn Clover published a series of great photoshop work. He looked for the location of the famous photographs from 1906 after the great earthquake and took own recent images, then blended them to create an astonishing effect. It’s perfect to illustrate the earthquake effects in the city and makes it easier to imagine the dimension of that catastrophe. See his website with the photo series part I and part II.

AEQUA website

Our Spanish colleagues from the Spanish Quaternary Research Association (AEQUA) have set up a new website for the focus group Tectónica Activa, Paleosismología y Arqueosismología QTECT-AEQUA Responsables de Grupo de Trabajo. Check out for latest news!

Boudinage in a Milchschnitte

Our colleagues from the Structural Geology, Tectonic and Geomechanics Group love to use food for analogue modelling – cake geology. Their latest movie demonstrates how to boudinage a Milchschnitte:

Help to save Siccar Point (if you like)

One of the most famous outcrops in the world, Siccar Point, is threatened by plans to build a trench and a dump for agricultural waste. There thousands of geologists have visited one of the classical outcrops of their discipline. If you don’t like that idea, visit this website and spread the word. Maybe it’s just a harmless pipe and nobody will recognize it, maybe it will destroy a point of special scientific interest. Thank you.


Have a nice weekend!
