What experts would say
Plain-language interpretation of current USGS data — not a direct expert quote or earthquake prediction.
This magnitude is large enough to be felt across a broad area. Actual impact depends more on shaking intensity, depth, distance and building vulnerability than magnitude alone.
Community reports currently indicate CDI 4.8, so felt shaking is being reported beyond a purely instrumental detection.
