Very true - I think most people assume an assembly point is "safe", as the location is chosen because it is low-risk for many types of disasters. 

Perhaps we need to have a few assembly_point:foobar=yes, in case people want to map a specific aspect of one - especially if it is *not* good for one aspect. 

Tsunami (height in M) 
Flood (out of the path of a possible dam breach, levee break, or flash floods. 
Tornado (assumed no, yes has to be explicit)

With certian assembly points, the idea it is "safe" from a tsunami is very important. Tornadoes will be basements/bunkers/buried shelters, possibly fallout shelters. 

But this would be a very small minority of assembly_points. Most will have no :foobar=tags. 

Perhaps if we can say :tsunami=25 means it is 25m above sea level (the safe top of the structure) or tsunami=yes/no to say at least go/don't go here. Same with tornado. 

Many of the assembly points in Japan are chosen specifically because they will not be flooded if a nearby dam bursts, to be away from known landslide risks, and to have no tall buildings nearby to fall in an earthquake. 

:Purpose=foobar locks you into a certian purpose, Whereas :tsunami=yes just means it is "safe" from a tsunami - *if you care to map that*. 

Besides tornado, all are implied yes, so an the assembly point inherits all the implied traits.
