Why did some reports say 3.5?

Magnitude estimates can change as more seismic readings are reviewed. The USGS catalog now gives this event as 3.6; the difference from an early 3.5 report does not mean the earthquake grew stronger after it happened.

What does the felt-report count mean?

It counts people who told the USGS they felt shaking. It is not a count of injuries or damage, and the total can change as more reports arrive.

The USGS event catalog is the live record. Measurements and felt reports may be updated.
