Magnitude estimates

Different scales measure different things and differ by a few tenths. The USGS marks one as preferred, and it is the one this page uses.

Mag.	Scale	Computed by	Notes
4.3	Mwr, regional moment	Alaska Earthquake Center	Preferred · Preliminary
4.3	Mwr, regional moment	USGS National Earthquake Information Center	Reviewed · ±0.03 · 106 stations
4.5	ML, local (Richter)	NOAA National Tsunami Warning Center	Reviewed · 29 stations

Tsunami

The USGS flags a quake this large in an oceanic region. The flag does not mean a tsunami happened; the tsunami warning centers decide that, and their messages are below when they issued any.

Current tsunami warnings: tsunami.gov. Warnings in force in the US also appear on our alerts pages.

Shaking
