  <www.seismicportal.eu/eventid/api/convert?source_id=us2000k7ki&source_catalog=USGS&out_catalog=UNID>

  EMSC ID : 754693

  <www.seismicportal.eu/eventid/api/convert?source_id=us2000k7ki&source_catalog=USGS&out_catalog=EMSC>

• Verify the UNID on the search page of the Seismic Portal

  • minimum magnitude: 5
  • from 2019-03-30 to 2019-03-31
