Caledonian Folding in Norway

Caledonian folding in Saltstraumen, Bodø, Norway

There are some rock faces that are simply spectacular, including this rock face in Saltstraumen, near Bodø in northern Norway. These fascinating folds have formed under distinct circumstances. About 490 – 390 million years ago the Caledonian Orogeny happened due to the continents of Laurentica, Avalonia and Baltica colliding. In Scandinavia, the collision involved Laurentica and Baltica only. The […]

Code your way to the Common Reflection Surface

Build a Common Reflection Surface Workflow in 6 easy steps

This article aims to be an in-depth article about building a workflow suited for proper use of the Common Reflection Surface. This resource is aimed at a specialist audience, however maybe this is a rare insight into the intricacies of seismic processing for some of our readers. The processing package for CRS is often regarded […]

Inge Lehmann Linocut

Artistic Inge Lehmann Linocut of the Danish Seismologist

Etsy user Minouette has a beautiful collection of linocuts. I really enjoyed the series on female scientists. Inge Lehmann is a Danish seismologist and the first scientist to prove layering within the Earth’s interior. An amazing achievement, especially, considering the quality of data back in the day. Have a look for yourself over here. The […]

Flash Flood in Utah

Flashflood in Utah triggers Debris Flow

On August 30th massive rain storms precipitated huge amounts of water in this basin in Utah. These then travelled along a canyon in a flashflood and triggered a debris flow.   Additionally, there is drone footage following the front of the flow. It is amazing how rain can trigger such a force of nature. Unfortunately, […]

Volcano monitoring on the next level

Volcanoes are being monitored for quite some time now. Deformational changes and seismicity can be recorded with decent accuracy. However, the link to volcanic activity has been unclear the entire time. But recent research might shed light on this matter. Let’s take a quick tour under some volcanoes. Down below When we look into the […]

The difference of a decimal for a tsunami

Off the coast of Chile a strong shallow earthquake triggered a tsunami. Warnings have been going out to Chile, Peru, Hawaii and New Zealand. The first estimation of the energy of the earthquake was at M7.9 but was then corrected to 8.3. This correction results in an update of the tsunami predictions. I created this […]


Rethinking the Common Reflection Surface Processing Tool

I worked with the seismic processing algorithm Common Reflection Surface for the past years. During this time I have come to the following conclusion: CRS has a marketing problem. I have worked with CRS in university, at Fugro Seismic Imaging and Wester Geco, respectively Schlumberger. Its development is closely tied to advanced concepts like the […]

Become a scientist!

This beautiful shirt tells it how it is. Except maybe that rarely any invention is named after the one who found it anymore.

Science needs you. Become a scientist! The benefits are clear:

  • Work on your free weekends
  • Incredibly low wages
  • Study cool stuff
  • Wear a lab coat

Your mileage may vary. Yay Science!

I find it hard to believe that it his come so far that the poor state of science has made it onto mass produced t-shirts.

Challenger Deep

Exploring Challenger Deep

The Challenger Deep at the Marianna trench is the deepest point on earth measuring 10.91km. People used to think our oceans were pretty flat underneath the water and did measurements with a plumb. So when surveyors came to this particular point at this subduction zone the line proved to be too short. When tectonic plates […]

The True Size of Countries

The true size of countries changes our perception of the world. Maps have so many uses in modern society. Google Maps and the navigation included, where the main reason I got my first smart phone. But maps have one significant flaw. Every map is a projection of a 3D object onto a 2D plane. That […]
