+# Conterminous U.S. Seismicity Catalogs
+
+For each update of the conterminous U.S. (CONUS) National Seismic Hazard Model (NSHM),
+seismicity catalogs (full and declustered) are developed as input to the smoothed 
+seismicity model. Catalogs are developed separately for the central and eastern U.S.
+(CEUS) and western U.S. (WUS) due to different input catalogs as well as magnitude 
+conversions. 
+
+Development of the seismicity catalogs include:
+
+- reformatting and combining pre-existing input catalogs,
+- deleting duplicates, explosions, and mining-related events,
+- flagging induced events in the CEUS, and
+- delivering a final uniform moment magnitude catalog for further processing 
+(i.e., declustering).
+
+[Mueller (2019)][1] outlines the full set of catalog processing steps in further detail.

+# Conterminous U.S. CEUS Full Seismicity Catalog
+
+The full catalog for the central and eastern U.S. (CEUS) can be found in file emm_pn.c2
+(file emm_pn.c2.pdf is a plot of this catalog file; blue boxes are induced seismicity zones
+where induced seismicity is removed from the catalog). A description of each column in file
+emm_pn.c2 is listed below:
+
+Column 1: Mw (nonspecific momement magnitude)
+Column 2: Longitude (degree east)
+Column 3: Latitude (degree north)
+Column 4: Depth (km)
+Column 5: Year
+Column 6: Month
+Column 7: Day
+Column 8: Hour
+Column 9: Minute
+Column 10: Second
+Column 11: Sigma_M (Magnitude uncertainity/standard deviation of the magnitude error)
+Column 12: Mwe (expcected value of Mw)
+Column 13: N* (counting factor)
+Column 14: Comment field
+
+
+File in_ce1.geojson is the polygon that defines the collection region of input catalogs
+and file in_ce2.geojson is the polygon that defines the final region of the full CEUS
+catalog.
