A global team of scientists have announced the results of an unprecedented collaboration to search for the source of the largest ever seismic event recorded on Mars. The study, led by the University of Oxford, rules out a meteorite impact, suggesting instead that the quake was the result of enormous tectonic forces within Mars’ crust.

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...

Scientists said Tuesday they might have detected the first known seismic tremor on Mars in a discovery that could shed light on the ancient origins of Earth’s neighbour. A dome-shaped probe known as SEIS landed on the surface of Mars in December after hitching a ride on NASA’s InSight spacecraft. Its instruments measure surface vibrations caused by weather but are also capable of detecting movement from deep within the planet—so called “marsquakes”—or those caused by meteorite impacts.

The French space agency Cnes, which operates SEIS, said it had detected “a weak but distinct seismic signal” from the probe...
