What does a marsquake look and feel like?
Southern California got all shook up after a set of recent quakes. But Earth isn’t the only place that experiences quakes: Both the Moon and Mars have them as well. NASA sent the first seismometer to the Moon 50 years … Continue reading

Do ice-squeezed aquifers cause marsquakes?
As the Mars InSight lander begins listening to the interior of Mars, some scientists are already proposing that some marsquakes could be signals of groundwater beneath the frozen surface of the Red Planet. The idea, proposed by Michael Manga, a … Continue reading

InSight: First likely marsquake detected
NASA’s Mars InSight lander has measured and recorded for the first time ever a likely “marsquake.” The faint seismic signal, detected by the lander’s Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander’s 128th Martian … Continue reading

Boulder trails suggest possible recent marsquakes
[Editor’s note: From a paper by Jason Brown and Gerald Roberts co-authors recently published in the Journal of Geophysical Research.] Possible evidence for variation in magnitude for marsquakes from fallen boulder populations, Grjota Valles, Mars Boulder trail populations were measured … Continue reading

HiRISE: Possible rock falls on steep slopes
Possible rock falls on steep slopes in Cerberus Fossae. Our goal here is to take “before” images at HiRISE resolution in order to identify fresh rockfalls that might be able to be associated with seismic events or Marsquakes detected by … Continue reading

Searching for signs of marsquakes
Rovers and landers have been studying Mars’s surface for decades, but the inner workings of the Red Planet are still mysterious. No one yet knows for sure what sort of seismic activity rocks the Red Planet. That’s not for lack … Continue reading
How active is Mars seismically? A prediction
The Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) mission arrives on Mars in November 2018. In anticipation of its arrival, a group of researchers led by Dr. Ana-Catalina Plesa have focused on the seismic experiments, which aim to … Continue reading

‘Marsquakes’ could shake up planetary science
Starting next year, scientists will get their first look deep below the surface of Mars. That’s when NASA will send the first robotic lander dedicated to exploring the planet’s subsurface. InSight, which stands for Interior Exploration using Seismic Investigations, will … Continue reading

Watch for falling rocks
A new investigation of Cerberus Fossae using HiRISE images shows that Mars is probably seismically active now or in the recent past. The clues are tracks left by boulders as they rolled downhill. Gerald Roberts (University of London) and colleagues … Continue reading
