There is an "island" with harpies west from the base. Clear it and displace Hanna there, she can't leave until you displace her again (use a flight bracelet). Just keep somebody around in case angels try to get her.

Of course, you can also block her path or displace her back to the base every so often, but this way requires less attention and resources.
