Marsquakes happen when rocks in Mars’s crust fracture under heat and stress, and when meteoroids strike the planet. Unlike many familiar earthquakes on Earth, they are not driven by moving tectonic plates: Mars has no Earth-like system of shifting plates.
What causes marsquakes?
Marsquakes have more than one source. NASA describes many as fractures or faults forming in the crust as heat and stress act on Martian rock. The absence of Earth-like plate tectonics does not mean Mars cannot have active faults or seismic activity. NASA’s account of InSight’s study of the Martian core explains the role of crustal fractures, while its overview of how InSight studied Mars’s inner layers describes seismic activity more broadly.

Crustal fractures
As stresses build in rock, a fault or fracture can slip or form, releasing energy as seismic waves. Mars does not need moving plates for this process: heat and stress within its crust can produce fractures and shaking.

Meteoroid impacts
A meteoroid striking the surface also sends seismic waves through Mars. NASA linked an InSight-recorded magnitude 4 event to a meteoroid impact after orbital imagery revealed a new crater. That case shows how researchers can combine a seismic record with surface observations to identify an event’s source. NASA’s report on impact-generated marsquakes describes the finding.

These sources establish that both internal fracturing and impacts occur, but they do not establish what percentage of all observed marsquakes comes from each cause.
How are marsquakes different from earthquakes?
| Comparison | Marsquakes | Earthquakes |
|---|---|---|
| Tectonic setting | Mars has no Earth-like system of moving tectonic plates. Crustal fractures can still form under heat and stress. | Many familiar earthquakes are associated with faults and moving tectonic plates. |
| Other established source | Meteoroid impacts can generate seismic signals. | The sources cited here do not provide a full classification of earthquake causes on Earth. |
| Seismic-wave behavior | InSight recorded signals with differing wave behavior: some more Earth-like and others more Moon-like. | In NASA’s comparison, earthquake waves travel more directly than the scattered waves associated with Moonquakes; Mars shows behavior between those patterns. |
| Observation conditions | InSight’s SEIS instrument measured ground motion, but wind vibration could obscure some events. | The available sources do not support a like-for-like comparison of detection rates or typical magnitudes. |
The difference is not that Mars is geologically silent. Rather, its seismic events arise in a different tectonic setting, and the waves recorded there do not all behave alike. NASA describes the two observed types as more “Moon-like” and more “Earth-like.” Its report on InSight’s quake detections discusses both wave behavior and wind noise.

NASA’s InSight lander carried the Seismic Experiment for Interior Structure, or SEIS, to measure ground motion. As seismic waves travel through different materials, their signals change. Researchers use those changes to infer properties of Mars’s crust, mantle, and core. NASA’s InSight science overview describes the mission’s interior-study goals.

Wind can vibrate the lander and mask some seismic signals, even with shielding. A recorded event is therefore evidence from an instrument operating in a particular environment—not a complete count of every quake that occurred. For impacts, matching a seismic signal to orbital observations of a fresh crater can help distinguish an impact from an internal source.
Can marsquakes be compared with earthquakes by frequency or strength?
Not on the evidence summarized here. The cited NASA sources establish causes and differences in wave behavior, but they do not provide comparable datasets for how often marsquakes and earthquakes occur or their typical magnitudes. Individual event magnitudes cannot establish a general planet-to-planet comparison.
