This fits "Anything that good hackers would find interesting." "anything that gratifies one's intellectual curiosity."
Major world events are pretty much always on topic. We just don't need minor regular news events here.
So that can literally be anything...
> If they'd cover it on TV news, it's probably off-topic.
This caveats it nicely. This is certainly off-topic for HN.
Probably !== certainly. The only people who can really speak to something being certainly off-topic are the moderators.
Sure, it fits, but HN is a notoriously inferior general news site.
If you heard about this first here, you're ill informed.
If this was your only source for this news, you're VERY ill informed.
It's a shame, HN first descended into being basically just a Reddit Subreddit hosted on a differently URL, and is now morphing into reddit.com/r/reddit.com (the anything-goes general reddit subreddit) with a slightly more technical audience.
Considering that the most useful link/comment in this thread is a link to a vastly superior, just incomparably more useful and informing reddit link, I think the point is made quite nicely.
Oh well, I guess HN is a wrapper around Reddit these days.
Edit: I live in Japan. I don't rely on HN for earthquake news.
I'm aware of the warning sirens. I spent a non-significant amount of time near the cost. You also don't need the news to tell you that you just felt a large earthquake, get to high ground.
