Why it matters

A reviewed M6.6 on the USGS significant feed is the interrupt meter: big enough to light the board, shallow enough to watch, with the tsunami flag still off and no PAGER alert color posted yet. The stamp itself is the signal — watch the USGS event page if mag, depth, or alert revise.
