The seismic event, known as 'S1222a', had a magnitude of 4.7 and caused vibrations that echoed through the Martian surface for at least six hours.. a)..
An international team of scientists led by the University of Oxford has unveiled the source of the largest ever seismic event recorded on Mars...
The research, published in the journal Geophysical Research Letters, dismisses the possibility of a meteorite impact, suggesting instead that the quake was triggered by massive tectonic forces within Mars' crust...
Given its seismic signal's similarity to previous quakes caused by meteoroid impacts, the team initially suspected an impact origin for this event and initiated an international search for a new crater...
The team concluded that the event was caused by the release of enormous tectonic forces within Mars' interior, indicating that the planet is more seismically active than previously thought..
