Extent
The CERI catalog includes both the NM and SE network codes.
The SE network authoritative polygon covers the eastern part of the CERI catalog with the following vertices:
36.6270 -88.6203
37.6270 -86.6797
38.8000 -85.0000
39.0000 -85.0000
39.0000 -77.2500
38.3500 -77.2500
38.0000 -76.3000
35.9530 -75.5817
32.2235 -79.6552
32.0000 -81.0800
32.0000 -85.0000
33.0000 -88.4165
34.0273 -88.4165
36.6270 -88.6203
Contributors
- The NM network code includes contributions from St Louis University and the USGS and, more recently the AG network funded by the Arkansas Geological Survey.
- The SE network code includes contributions from Virginia Tech, the University of South Carolina and others (see SEUSSN at the VA Tech website).
- Current real-time data from several sources is used to produce event information. Those contributors include
- NM, CERI at the University of Memphis
- NM, St. Louis University
- AG, Arkansas Geological Survey
- ET, CERI at the University of Memphis
- KY, University of Kentucky
- CO, University of South Carolina
- SE, Virginia Tech
- TA, IRIS
- US, USGS
- N4, IRIS/USGS
Note 1:
Because the network has evolved over the years, there is no guarantee of consistency in detection threshold, magnitude determination or region covered. The data in this catalog come from numerous sources:
- 1974-1992: TEIC earthquake bulletin and St Louis Regional Catalog
- 1993-1994: Saint Louis University and Central Mississippi Valley Earthquake Bulletins
- 1995-present: earthquakes reported by SLU and/or CERI
- 2003-present: addition of CERI East TN earthquakes and contributions from the SEUSSN bulletins
