Loudness is related to the amplitude of sound waves (or pressure amplitude/ displacement relative to atmospheric pressure, typically), whereas intensity is the rate at which power (rate of energy transfer, or work per unit time) is transferred across a given area (Power/Area, or rate of energy transfer per unit area; units of watts/m2).
