Tsunami warning status
None of the earthquakes in Montana in the past 30 days carried the USGS tsunami flag, which USGS sets for large quakes in oceanic regions where the tsunami warning centres issue messages.
Official tsunami warnings come from the NOAA tsunami warning centres (tsunami.gov) and national agencies; follow local authorities if you are on a coast after strong shaking.
USGS lists every magnitude in the United States but outside it coverage is complete only from about M4–4.5, so smaller local quakes reported by national agencies may be missing. Magnitudes and locations are revised for hours after an event. A quake belongs to Montana when the nearest city within 150 km is there, otherwise by the USGS place name.
