Where Oklahoma sits in the catalog
Rank 10th of 39 tracked U.S. states and territories (74th percentile by M4+ count since 2005). On the M4+ activity ladder Nevada sits immediately above at 170 events and Idaho sits immediately below at 73.
No M6+ events on the significant record
Oklahoma has catalogued M4+ activity since 2005 but zero magnitude-6.0-and-above events in the USGS significant series back to 1900. The nearest tracked jurisdiction that does carry an M6+ record is Idaho (73 M4+ · 2 M6+).
