M 2.8 - 11 km W of Mayagüez, Puerto Rico

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
