The USGS earthquake hazards map excludes earthquakes caused by human activities such as pumping wastewater from hydraulic fracturing or injecting carbon dioxide deep underground.
Notes on verification
Confirmed by USGS's own official documentation of the National Seismic Hazard Model and corroborated by Eos and Congressional Research Service reports. Minor nuance: exclusion occurs at the input catalog stage rather than being a post-hoc map filter, but practical effect matches the claim. [tier=gold indep_score=0.983 clusters=3 claim_tier=notable]
