The relatively powerful earthquake that hit eastern France last Saturday confirms the findings of the postgraduate research currently being conducted by Gideon Lopes Cardozo at the Université Louis Pasteur in Strasbourg and the Faculty of Earth and Life Sciences at the VU Amsterdam. Lopes Cardozo is investigating the causes of earthquakes in the southern part of the Rhine Graben. His research is sponsored by the European Union and has shown that the movements in the earth’s crust in the area around the Rhine occur along fault lines that have a long geological history. Until recently, it was thought that these movements actually took place more often on younger fault lines.
The earthquake, measuring 5.4 on the Richter scale, occurred at a depth of ten kilometres below the town of Saint-Dié in central Vosges. The Vosges are formed as a part of a mountain range that covered a large area of central Europe three hundered million years ago. The ancient fault lines that developed at that time became zones of weakness in the earth’s crust. If stress in the earth’s crust recurs, these are the zones most likely to move. Because of this, they have been used time and again throughout geological history for movements in the earth’s crust and are more often the focus of seismic activity.
In the course of the past millions of years, the existing subterranean fault lines north of the Alps have been re-activated by a collision between the African and European plates. The Alps are the most obvious result of this. Earthquakes in the Vosges and the adjacent Rhine Valley (stretching even as far as Roermond in the Netherlands in 1992) are also caused by the stresses resulting from this collision.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
