Earthquakes, past hour
Every earthquake detected worldwide in the last hour, as Atom with georss coordinates on each entry.
This is the entry to reach for when you want a feed whose content genuinely changes and genuinely matters. It is small, it updates constantly, and every entry carries structured position data rather than prose.
It is also a proper Atom document — id, title and updated on the feed and on every entry — which makes it a fair test of a reader that claims to support the format.
