If I have a research & mining outpost established on the surface of Europa, in which there is a small complex of buildings, how do I claim to have them protected from potential breaks in the ice (either from proposed tectonic activity or thermal vents breaching the ice)?

Things I've considered:

Having all of the buildings compose a singular ground-unit to maintain the outpost integrity in the event of a break in the ice.

Having the buildings mobile in a way that can travel over ice (i.e. treads) to allow for movement in the event of ice shifting or breaking.

Neither of these are truly protective measures though, so how can I justify that they're protected enough to bring the level of risk into acceptable levels? I mean I have to convince people to want to go in the first place.
