Any Martians on the market ought to study to duck and canopy.
On May 4, the Red Planet was rocked by a roughly magnitude 5 temblor, the most important Marsquake detected so far, NASA’s Jet Propulsion Laboratory in Pasadena, Calif., studies. The shaking lasted for greater than six hours and launched greater than 10 occasions the vitality of the earlier record-holding quake.

Cerberus Fossae is thought for its fractured floor and frequent rockfalls. It is smart that the bottom could be shifting there, says geophysicist Philippe Lognonné, principal investigator of the Seismic Experiment for Interior Structure, InSight’s seismometer. “It’s an ancient volcanic bulge.”
Just like earthquakes reveal details about our planet’s inside construction, Marsquakes can be utilized to probe what lies beneath Mars’ floor (SN: 7/22/21). And so much could be discovered from finding out this whopper of a quake, says Lognonné, of the Institut de Physique du Globe de Paris. “The signal is so good, we’ll be able to work on the details.”
