BTW, it turns out there's a registry of volunteer drone pilots for doing SAR (search-and-rescue) called SWARM, whose website is this:

I don't know how helpful this would be for the current situation, given that the California pilots seem not to be at all close by (at least the cities I recognize), though perhaps the list is worth a look:

(There's also a guide for volunteer pilots on procedures that might be helpful:
