USGS catalogue already lists seven quakes of M5.5 or higher in the window
The question
Will there be 7 earthquakes of 5.5 or above magnitude worldwide?
The USGS catalogue, checked at 12:02 UTC on 4 October 2026, listed seven earthquakes of magnitude 5.5 or higher between 28 September and 4 October (Eastern Time). That is the figure that decides the question, and it already meets the threshold of at least seven. About 16 hours of the window remained at the time of the check. The seven events run from a 5.5 on the southern Mid-Atlantic Ridge on 29 September to a 5.5 in the Volcano Islands region of Japan on 4 October. In between are 5.6 events near Yonakuni and Tamarindo, a 5.8 near Vilyuchinsk, a 5.9 near Tambolaka and a 5.6 near Banda Aceh. The main risk is revision. Two of the seven sit exactly at 5.5, and a downward revision of either would cut the count. Magnitudes can be revised, and the rules allow 24 hours after the window closes for that. Further quakes in the remaining hours would offset such a loss. Over the past 365 days, M5.5 or higher events averaged 1.32 per day. The median 168-hour window held 8 events, and in 55% of comparable spells at least one more event arrived within 16 hours. This is context from the catalogue's history, not a prediction for any particular hour. The thing to watch is the magnitudes of the two 5.5 entries. A downgrade of either, with no new qualifying quake to replace it, would be the clearest way for the count to fall below seven.
