The moonquakes are concentrated at great depth—between 600 km and 1000 km—which is deeper than earthquakes. The difference in distribution and magnitude of seismic energy relase on the earth and the moon is probably related to fundamental differences in interior dynamics.
How are moonquakes similar to earthquakes?
The moonquakes are probably a result of the moon's ongoing contraction. The moon is still tectonically active, like Earth, generating moonquakes as our planet creates earthquakes, a new study based on Apollo mission data found.
How are Marsquakes different from earthquakes?
A marsquake is a quake which, much like an earthquake, would be a shaking of the surface or interior of the planet Mars as a result of the sudden release of energy in the planet's interior, such as the result of plate tectonics, which most quakes on Earth originate from, or possibly from hotspots such as Olympus Mons …
How do the numbers and magnitudes of moonquakes compare to earthquakes?
In comparison, deep moonquakes give b-values generally in excess of 1.5 (Lammlein et al., 1974), while most earthquakes give values close to 1.0 (Matuzawa, 1964). The low b-value for the shallow moonquakes means that large moonquakes are proportionately more abundant than in normal earthquakes.
Are moonquakes worse than earthquakes?
The largest moonquakes are much weaker than the largest earthquakes, though their shaking can last for up to an hour, due to fewer attenuating factors to damp seismic vibrations. Information about moonquakes comes from seismometers placed on the Moon from 1969 through 1972.
Does Earth’s gravity cause moonquakes?
A new analysis of data gathered by the Apollo missions confirms that tidal stress – the gravitational pull of the moon on the Earth and of the Earth on the moon – is responsible for causing deep moonquakes, the lunar equivalent of earthquakes.
Does the moon have moonquakes?
Moonquakes – as they are known on the moon – are produced as a result of meteoroids hitting the surface or by the gravitational pull of the Earth squeezing and stretching the moon's interior, in a similar way to the moon's tidal pull on Earth's oceans.
Are there marsquakes on Mars?
A new analysis of seismic data of NASA's InSight mission suggests that Mars could have an earthquake season. Researchers observed that certain kinds of marsquakes became more frequent beginning in the northern spring with a peak in the summer.
Do moons have moonquakes?
