Mars is, by Earth's standard, tectonically inactive. You should not expect dangerous marsquakes.
Mars is hydrologically impoverished: you should not expect flooding.
Meteorite impacts might be more severe because of the reduced atmosphere, so more small impacts should be expected. Medium and large impacts should be about the same: rare.
The biggest problems on Mars are air, water, and temperature. All of these have scalar efficiencies, so I suspect an optimal arrangement for Mars would be three cities not very far from each other, so as to be able to provide mutual support while avoiding single points of failure.

- stjohnswarts 5y agoSo how exactly would you know where said lava tubes exist?
