Problem: most assembly points are multi-purpose around here. At least fire and

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.
Some are atom bomb shelters.
Some are in the open, possibly a car park - away from the building where the
alarm has been activated - usually a fire alarm.
Some 'multi purpose' assembly points would also be used for bomb threats.
For bomb threats the location should not be known nor regular as the bomb could
be placed within the assembly point to cause maximum devastation.
This kind should not be mapped.
Tsunami (height in M)
Earthquake
Fire
Landslide
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.
