on the only major fault line in NH or Mass, we haven't had a
noticable earthquake in over 50 years. there is no geothermal
activity (volcanoes). even Nor'Easters aren't common. no
plagues of locusts lately (although were due for tent
caterpillers again). it's generally too wet for a major forest
fire & floods aren't common either...

You probably shouldn't discount the possibility of a major
regional wildfire, and the EPA rules against clearing
underbrush aren't calculated to make that less likely.
Admittedly, it would take a significant drought first,
so they're not likely to sneak up on you.

There's also ice-storms and blizards, co-incident or not
with major flooding.

A good ice-storm followed by 10' of snow and a period
of high winds could easily cut people off from government
and municiple services for a couple weeks at a time.
