- Researchers at ETH Zurich have achieved something spectacular.
- They have observed surface waves on a planet other than Earth for the first time ever.
- As a result, researchers at ETH Zurich gained surprising insights into the structure of the Martian crust.
Thanks to two meteorite impacts on Mars, the researchers were able to evaluate sky waves propagating along the surface of the planet for the first time. It turned out that the crust of the planet is structured differently than expected.
New insights into structure
So far, only a point measurement of the Martian crust was available, as Doyeon Kim, Senior Assistant at the ETH Institute for Geophysics, writes in a study published in the journal Science. Three layers of the crust were detected.

So far, only tremors deep inside the planet have been recorded on Mars. The ETH researchers have now been able to document the crater after a meteorite impact.

The surface waves, which have now been evaluated for the first time, paint a different picture, as Kim continues to write. The Martian crust between the impact sites of the meteorites and the seismometer, which were about 3500 and 7500 kilometers apart respectively, has a very uniform structure on average.
