The USGS identified 28 million people living in areas where 'pretty strong ground shaking' is expected within the next 50 years.
Notes on verification
Confirmed by USGS official news release, peer-reviewed publication (Jaiswal et al., 2015, Earthquake Spectra), and independent media corroboration (National Geographic, Fox News/AP). All sources consistently report the 28 million figure tied to high seismic hazard over a 50-year period. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable]
