USGS PAGER Events
- Marjorie Lucas
Overview
The USGS Prompt Assessment of Global Earthquakes for Response (PAGER) service provides estimates on the scope of impact earthquakes will have. The service publishes events that contain basic information such as earthquake magnitude, location, and date of occurrence, but also includes an alert level, which corresponds to estimated fatalities and economic loss.
For more details regarding the service, visit the service home page: https://earthquake.usgs.gov/data/pager/
SDS Pipeline
Automated Submission
The ARIA pipeline queries the PAGER service every five minutes by submitting a PDL job via cron. The default parameters for this job vary depending on the alert level queried. The stdout belonging to a successful job is shown below. For a red alert level, no magnitude constraint is specified; for yellow, only events with a magnitude of at least 6.0 will be ingested; for green, only events with a magnitude of at least 7.0 will be ingested. No events were ingested for this specific query.

--------------finished query--------------If the query had returned an event, a job to create an AOI would have been submitted and a slack message would have been published to the aria-sds channel.
On-Demand Submission
Operators may also submit on-demand PAGER query jobs. Operators must facet over the geographical area of interest then select the PAGER Query PGE and enter the parameters. The job will then run much like the automated job submission and submit jobs to create AOI’s for events that are returned; however, no slack messages will be published using the PGE version referenced below.
