As I recently showed from InSight mission 2018-2020 data, seismicity on
magnetically defenseless Mars arises in a planetary rupturing response
to Rieger instability of the interplanetary magnetic field (IMF) in the
1-6-month (385.8-64.3-nHz) band of highest solar-system energies. I next
examine lunar and terrestrial seismicity in the same bend. Moonquakes
and earthquakes during traversals of the Earth magnetotail were analyzed
separately from IMF events to decouple magnetosphere and IMF effects.
The analysis showed with 99-67% confidence and very high
(Φ>>12) fidelity that (an unspecified majority
of) moonquakes and Mw5.6+ earthquakes also reoccur at Rieger periods.
About half of the spectral peaks split but into clusters that average to
the usual Rieger periodicities also, where magnetotail reconnecting
clears the signal. This confirmation of the Mars result means that
Rieger disturbance of the IMF co-drives dynamics of solid-surface
bodies, including the Moon and, to an extent, magnetically shielded
