'Intensität' (intensity) is the noun corresponding to the adjective 'intensiv' (intense). The ending '-ität' is a typical way to form abstract nouns from adjectives that describe a property or state.

To say what the intensity of something is being measured for, you usually use the genitive or the preposition 'von' with the dative. The genitive is more common in written language.
