Forwarding to the realtime-feed-users list, realtime-feeds is only for
announcements.

Hi,

I'm looking to understand the difference between the location reported in
the Atom feed entry title vs that reported in the attached CAP alert
headline.

It appears that the Atom title is an approximation of the epicenter
location, represented in kilometers from the nearest large-ish city, and
the CAP headline is a (frequently different) nearby city.

1. Can you explain how the cities are chosen in each case?
2. Is there a reason that the two are different?

The CAP headlines look somewhat inaccurate when the earthquake is far out
to sea and the closest city is hundreds of kilometers away.

Here are a few examples, pulled from
http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/4.5_week.atom
currently

CAP alerts are generated by an older system that still uses Flynn-Engdahl
region names.  Our newer systems use cities from geonames.org .

We plan to update our CAP alert generator, but currently have other
priorities.  CAP alerts will eventually use the same information displayed
by the ATOM and other feeds on this page:

http://earthquake.usgs.gov/earthquakes/feed/v1.0/



The format that provides access to all event information as it was
contributed, including CAP alerts, is the GeoJSON detail feed:

http://earthquake.usgs.gov/earthquakes/feed/v1.0/geojson_detail.php


Links to GeoJSON detail feeds are included as a "detail" feature property
in GeoJSON summary feeds.


Thanks,

Jeremy

Subject: [Realtime-feed-users] GeoJson feed problems
Message-ID: <D906B7EA-973A-4782-9DE2-A7D44D622110@artisanglobal.com>

Hi,

Is there something wrong with the GeoJson Feeds? Many of our users are reporting that they cannot access the feeds - and our cloud based automated server process has been failing consistently since last night (it checks the one day 2.5 GeoJson feed every two minutes).

The problem is not consistent across our user base. I am able to access the feed from my phone but our server process is consistently failing. Perhaps there is an issue with a CDN node?

Thanks in advance for your prompt attention!

Kind regards,
James
