According to a media report, there was a severe earthquake on Mars. It is even said to be the strongest that has ever been detected on any other celestial body. However, experts are puzzled by the observation of the NASA probe.
On May 5th, it is said that there was a big crash on the planet Mars. Simon Stähler, part of an international team evaluating the measurements of the “Seismic Experiment for Interior Structure” (SEIS) on the US Mars probe “Insight”, says in an interview with “Spiegel Online”: “It is the most powerful earthquake that has ever been detected on any other celestial body.”
He and his colleagues had not foreseen the magnitude 5 earthquake. On the contrary: It was a real surprise. Before that, the research team would only have measured small vibrations for 1200 Martian days. Unlike Earth, there is no plate tectonics on Mars. Friction or pressure between the earth plates usually lead to an earthquake on our planet.
The experts cannot explain the earthquake on Mars. Stähler, seismologist at the Institute for Geophysics at ETH Zurich, says: “We do not yet know in detail what triggered the current event and we are puzzled. The quake came from a place where we have not observed any other tremors.” You now scroll through geological maps and satellite images to find the source region.
When asked by “Spiegel Online”, Stähler said it was possible that a chunk falling on the surface triggered the earthquake. But there is no evidence for this.
