origin Product Documentation
« Back to Products Documentation
Types
- origin
- Origin products are currently read from EQXML messages.
- phase-data
- Similar to origin product, but underlying xml contains phase data.
This type of message is usually sent in addition to origin, because
the message is significantly larger.
- origin-scenario
- phase-data-scenario
- Scenario earthquakes.
- internal-origin
- internal-phase-data
- Preliminary locations that are not QC'ed for release to public.
Sources
- Network Code
- The contributing network.
Status
- UPDATE
- The product is not being deleted.
- DELETE
- The product is being deleted.
