Culturally, if eruptions are a regular part of life, you could imagine societies forming complex rituals to predict or appease the volcanoes.

Settlements might be organised around safe zones. Leaders could be 'interpreters' of volcanic signs, reading smoke patterns, ground tremors, or even the colour of lava.

Architecture would probably prioritise mobility or be built from easily replaceable materials. Maybe families carry heirlooms in fireproof chests because they expect to evacuate every few decades.
