Morphology
The meaning is directly compositional: 'volcanic' (connected with volcanoes) modifies 'activity' (process or occurrence), so a learner who knows both words can infer it refers to processes related to volcanoes (eruptions, emissions, etc.). This adjective+noun pattern is transparent and common across languages, so the sense is predictable for a B1 learner.
Etymology
Volcanic activity comes from the image of a volcanic cone showing activity, spewing lava, ash and steam. So, volcanic activity now means the 'eruptions' and other visible events a volcano makes.
