A new report from Brown University has discovered “Evidence of seismic activity” due to strange points scattered by the moon.
Scientists propose that the largest, oldest, and deepest impact crater recognized on the Moon, the South Pole-Aitken basin, could have rocked the moon to its core.
Geologists have found activity on the near side of the moon, perhaps more activity than many quarantined individuals have exhibited in weeks.
Observation of rocks and rocks on the surface of the moon suggests the recent movement of tectonic plates.
“There is an assumption that the Moon is long dead, but we continue to discover that this is not the case.” says planetary geologist Peter Schultz of Brown University.
“Based on this document, it appears that the Moon may still be cracking and cracking, potentially today, and we can see the evidence on these ridges.”
Furthermore, tectonic movement is not a new concept. Seismometers installed by Apollo astronauts decades ago show faint earthquakes far below the surface.

Shallow moon tremors are difficult for scientists to understand because the moon does not have tectonic plates like those found on Earth.
The recent study identifies more than 500 patches of exposed bedrock formed in a pattern on the moon’s surface. These patterns coincided with ancient and deep crack patches found in 2014.
“It’s almost a one-to-one correlation” Schultz said. “That makes us think that what we are seeing is a continuous process driven by things that happen inside the Moon.”
The document rules out global cooling or the stress of Earth’s tides as reasons for the activity, as hypothesized above. New findings suggest that the ridges are still increasing.
The combination of magma-filled ridges and crevices point towards the South Pole-Aitken basin as a culprit. In this model, the basin collision is believed to have produced the magma-filled active crevice system and rising ridges.
“Giant impacts have lasting effects” Schultz said. “The Moon has a long memory. What we are seeing today on the surface is a testimony to his long memory and secrets that he still keeps. “
