How did seismic waves make it possible to understand the internal structure of the Earth?
How to know the internal structure of the Earth? If the seismic method, by generation of artificial waves, today makes it possible to image in finesse the architecture of the…
These active faults that mark out France
The French territory inherits a long and complex tectonic history. Evidenced by the many faults that incise our basement. Many are still active. To understand them and assess the seismic…
The inner core of the Earth is not really solid!
Until now considered as solid, the inner core of the Earth would actually be in an intermediate state, between solid and liquid. This is demonstrated by a new study, whose…

When the mountains hum the seismic song of the Earth
Mountains are not as still as one might think. The summit of the Matterhorn in Switzerland oscillates imperceptibly in response to ambient seismic noise from Earth, a new study shows.…
Listen to the sound of the Earth to build an accurate image
How to image the interior of the earth’s crust? Seismic imagery provides solutions but its depth of investigation remains limited. However, researchers have just developed a new method based on…
