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 […]

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 […]

Ash plume over Europe

Progressing ash plume of Eyjafjallajökull

In May 2010 air transportation in Europe came to a halt, when Eyjafjallajökull on Iceland erupted. Now, two years after that eruption scientist have gathered and evaluated all kinds of data how the ash plume moved through Europe. This data taken from satellites, plane and the earth can help evaluate particle dispersion better and limit […]

Aran Islands, Ireland

Aran Islands, Ireland

The Aran Islands just off the coast of Ireland left geologists puzzled for a while now. On top of this cliff huge boulders are found. Up to now the only explanation for waves energetic enough to transport these rocks would be a tsunami. Unfortunately, at least for the explanation, no tsunami happened there since 1755. Now […]

Seismic Image with Hydrocarbon Indicator Interpretation

The subjective science of seismic interpretation

The final step in the work with seismic data is seismic interpretation. In a scientific field called geophysics, interpretation sounds highly subjective; Very different from the usual statistics, ray and wave phenomenae. This can’t be right, right? I’d love to say it’s very clear and seismic data reveals a perfect image of the subsurface. But […]
