Can the Intensify Aspect add multiple token types with Hazards Spread Across the Island?

No. Hazards Spread Across the Island can only add more of the chosen token you are adding, even if other tokens could have been chosen instead.
Similarly, if a Power allows adding multiple token types in combinations you choose (e.g., Utter a Curse of Dread and Bone), Intensify can only add extras of token types that are already being added. And if you could add tokens in multiple places (e.g., Spill Bitterness into the Earth), you can only add extra tokens where you already added tokens of that type.
