Need help with ER diagram
Since you have a 1-1 relationship between DisasterEvent and People now, you can not distinguish any relation between People and Place. If several Places are related to a single DisasterEvent, all those places are related to the same instance of People.

If you want to map the People affected by the Event at a Place, you should relate People to Place instead of to DisasterEvent.

As long as an event always occurs at at least one place, you can always relate your People to your DisasterEvent via the Place where it occurred.

On a sidenote, I would use Location instead of Place, and maybe the more precise Victims for People, as well as maybe Damage for Home.
