[Realtime-feed-users] Shake map generation question

[Fee, Jeremy]

Hello,

We have noticed that some GeoJson feeds contain Shakemap as a product type
> associated with an earthquake but do not provide point coordinates for that

The information was most likely not included in the ShakeMap product.  If
you provide a specific example I can take a look.

Typically, most updates occur within six weeks as information from other
organizations is received.  However, events may be updated at any time when
better information is available.

The API parameter "updatedafter" can be used to check for events that have
been updated since a previous search:

Thanks,

Jeremy
