Aftershock forecast

The chance of at least one aftershock this large or larger, from the USGS operational aftershock forecast, issued Mon, Sep 28, 2026, 4:42 PM UTC. The USGS updates it as the sequence unfolds.

Within	M3+	M4+	M5+	M6+	M7+
1 day	Over 99%	66%	8%	Under 1%	Under 1%
1 week	Over 99%	Over 99%	45%	5%	Under 1%
