usgs, Oct 15 2026The 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.
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.
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.
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.
