New Delhi, (PTI) The marsquake of May 2022 was caused by the release of enormous tectonic forces within Mars’ interior, suggesting that the planet might be more seismically active than previously thought, researchers say.
The quake with a magnitude of 4.7 and causing vibrations to reverberate through the planet for at least six hours had been recorded by US’s NASA’s InSight lander on May 4.
Because its seismic signal was similar to previous quakes known to be caused by meteoroid impacts, the team from the University of Oxford, UK, had initially believed that this event (dubbed ‘S1222a’) might have been caused by an impact as well.
