Do you know your seismic velocity?

In seismic data analysis a lot of work goes towards getting a good velocity model of the subsurface. We talk about the seismic velocity. However, this may lead to some serious misconceptions. One step in seismic processing is velocity analysis. We pick the velocity that adjusts our data for the best value. Usually this is […]

Know your scale – Why wavelengths are so important

So you thought there is just one “seismics”? In general, we might say that the seismics experiment is watching mechanical waves travel through Earth and then apply science on it to get an image of the Earth’s interior. However, this experiment and the science behind it has a high degree of uncertainty. When we conduct […]
