M 2.9 - 63 km ENE of Lake Minchumina, Alaska

The alert type is the category the source published. ARC Warning does not rename it and does not add an outcome the source did not publish.

Type

other

• ARC Warning methodology

Official means one official source published the record.

The label describes how the record was filed. It is not a statement about anyone's intent.

Verification

OFFICIAL

• ARC Warning methodology

High, medium, and low are ARC Warning display labels for how the record was filed. They are not a forecast.

When the source published its own number, such as an earthquake magnitude, that number is the measurement. The display label does not replace it.

Severity

low

• ARC Warning methodology

Magnitude is the catalog's measure of the earthquake's size. It is not a measure of damage, and it is not the intensity felt at a place.

Depth, when the catalog published one, is the depth of the hypocenter. A missing depth is not estimated.

Magnitude

Not available

• USGS, Earthquake magnitude, energy release, and shaking intensity
