I'm not sure if that's the best strategy.

1) An unpopulated region around the epicenter maybe is totally 
uninteresting.
2) even a populated region that's nearer e.g. to a on-sea epicenter of 
an earthquake/tsunami might be less interesting if it has not been hit 
that hard because of a different shore shape than another region more 
far away.

Perhaps I'm wrong, but that's why I don't think an automated (!) 
decision out of the "epicenter" information is useful.

On the other hand it's a nice idea to have an adjustable control 
strategy for the task scheduling, where "start at epicenter (x,y) and 
take the nearest" could be one example, as well as "this is the area and 
the most important part for the first run is the part along that 
river/motorway/mountain ridge..."

No idea how exactly that could be solved best.

would not set it to "steps" as some tasks may be dependent on the 
experience of a mapper: If I have no idea about how to "read" imagery 
about powerlines, I might better trace rivers and lakes first (given 
that roads are done), and probably on the long run there's some civil 
protection organisation that actively supports osm/hot mapping 
themselfes and there's the power coordination troup that is working on 
powerlines before streets are traced by mappers - but they trace it.

I know from the THW (German Federal Agency of technical relief) that 
they have groups to do power supply. In the first run the set up 
generators for their own needs and afterwards they start to repair and 
secure the power infrastructure (where possible and necessary).

In general OSM (speaking not HOT specific, so there may be tagging 
specifically for slums, too) doesn't define mapping according to law, 
but according to what's on the ground.

A slum where people live in is - on the ground, without looking into law 
books - some kind of residential area, as the people living there are 
residents, I would say.
Many slums on the world are de facto residential areas, even if not or 
not originally allowed by the authorities.

With that I would not use landuse=slum distinct from landuse=residential.
If - and I'm not sure about that, I would add a secondary tag to mark 
that residential area as slum; but keep in mind that there's often no 
hard line between slum, "usual residential area" and a camp built 
for/of/by people hit by a desaster.
