The window is still open. Tremor grades this automatically against independently ingested outcome events once it closes — the probability above is never revised.

Tremor publishes probabilities, not warnings, and is not an emergency service. For official alerts follow USGS, NOAA/NWS, NASA SWPC or your national authority.
