A 2019 marsquake may have sent boulders rolling

Science News reports that researchers comparing images from June 2019 and December 2020 found 27 new linelike features near Cerberus Fossae. The team says they were likely tracks left by bouncing boulders and that a nearby July 2019 marsquake recorded by NASA’s InSight lander probably triggered the rockfalls. The researchers suggest such tracks could help identify seismically active areas on Mars where seismic data is unavailable.
