Tsunami warning status
None of the earthquakes near Ageo in the past year 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.
Earthquakes around the world today
Worldwide, USGS listed 154 earthquakes of M1+ in the last 24 hours; the largest was M6.5 Bonin Islands, Japan region.
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.
