NASA’s InSight Detects Two Sizable Quakes on Mars

NASA’s InSight lander used a scoop on its robotic arm to begin trickling soil over the cable connecting its seismometer to the spacecraft on March 14, 2021, the 816th Martian day, or sol of the mission. Scientists hope insulating it from the wind will make it easier to detect marsquakes. (Credits: NASA/JPL-Caltech)

The magnitude 3.3 and 3.1 temblors originated in a region called Cerberus Fossae, further supporting the idea that this location is seismically active.

PASADENA, Calif. (NASA PR) — NASA’s InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae – the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5. InSight has recorded over 500 quakes to date, but because of their clear signals, these are four of the best quake records for probing the interior of the planet.
