Scientists are surprised by the source of the largest quake ever detected on Mars. The quake, which had a magnitude of 4.7 and caused vibrations to reverberate through the planet for at least six hours, was recorded by NASA’s InSight lander on May 4, 2022.
Initially, scientists thought that the quake was caused by a meteorite impact. However, a new study published in the journal Geophysical Research Letters has ruled out a meteorite impact. Instead, the study suggests that the quake was caused by tectonic activity within Mars’ crust.
This is surprising because Mars is not thought to have active plate tectonics. However, the study suggests that Mars may have a type of tectonic activity that is different from plate tectonics on Earth.
The study’s authors believe that the quake was caused by the release of stress within Mars’ crust. This stress may have been caused by the planet’s cooling and shrinking over time.
The study’s findings suggest that Mars is more geologically active than previously thought. This is good news for scientists who are studying the planet’s evolution.
