Value: Max M6.4, 4× M6+ (7d)
Rated on: No USGS PAGER orange/red alert and no M7+ in the past 7 days.

Largest quake this week M6.4; no high-impact alerts

Why it's at this level: USGS recorded 135 earthquakes of M4.5+ in the 7 days to 1 Nov, four of them M6+; the largest was an M6.4 south-east of Easter Island (29 Oct), and an M6.0 struck off Shima, Japan on 31 Oct. All PAGER alerts were green, with no M7+ and no tsunami flags.

What this means for you: No current high-impact earthquake. Earthquakes cannot be forecast; follow local guidance in seismic zones.

Why it matters: Large earthquakes can kill thousands in seconds and disrupt global supply chains (chips, cars).
What moves it: Tectonics — unpredictable; impact depends on depth, location and building standards.

Rubric — Alert: PAGER red, or a tsunami causing damage. | Watch: M7+ in the past 7 days, or PAGER orange, or a tsunami warning issued. | Normal: No USGS PAGER orange/red alert and no M7+ in the past 7 days.
