A comparative planetology study revealed that the Martian and lunar lava tubes are so massive and have high roof stability.
In comparison to lava tubes present in Hawaii, the Canary Islands, Australia, and Iceland, these lava tubes are 1 to 3 orders of magnitude more voluminous.
Researchers believe that most of the lunar lava tubes could withstand the collapses triggered by impacts/tectonics.
They can also act as shields against cosmic and solar radiation. Due to these protected and stable environments of lava tubes, it is suitable for exploration and potential settlement.
