Yes its interesting; you can easily imagine that the following trends are detected:

* "home and safe" "safe as houses" etc

* "safe in bed" "safely tucked up in bed" etc

* "volcano" ... no clear data. Certainly dangerous being a volcanologist, but that'd be great AI googlefu

* "pensioner attacked in park" .. "our parks are not safe" etc... Hmm, Parks are the most dangerous.

Because frequency of local newspaper reports is a bad measure for volcanos I guess.
