Every two weeks, we compare earthquake activity in major fault zones worldwide against each zone’s own long-term average. A zone that’s normally active but has gone unusually quiet may be building up pressure instead of releasing it regularly – here’s what the data shows as of November 12, 2026.
Zones With More Earthquakes Than Usual
- Bird's Head / Bismarck Sea boundary: 1 earthquakes in the last 14 days, releasing about 7.64x the seismic energy this zone usually releases in two weeks
- NA/PA: 3 earthquakes in the last 14 days, releasing about 5.5x the seismic energy this zone usually releases in two weeks (flagged in 1 prior report(s) too)
- NA/PA: 3 earthquakes in the last 14 days, releasing about 5.5x the seismic energy this zone usually releases in two weeks (flagged in 1 prior report(s) too)
- Pacific / Australia boundary: 1 earthquakes in the last 14 days, releasing about 4.81x the seismic energy this zone usually releases in two weeks
- Scotia / Antarctica boundary: 1 earthquakes in the last 14 days, releasing about 4.49x the seismic energy this zone usually releases in two weeks
- Bird's Head / Bismarck Sea boundary: 1 earthquakes in the last 14 days, releasing about 3.73x the seismic energy this zone usually releases in two weeks
Zones That Have Gone Quiet
- Australia / Somalia boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.05 (flagged in 1 prior report(s) too)
- India / Somalia boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.08 (flagged in 3 prior report(s) too)
- Africa / South America boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.08 (flagged in 1 prior report(s) too)
- Antarctica / Nazca boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.05 (flagged in 1 prior report(s) too)
- Pacific / Antarctica boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.08 (flagged in 3 prior report(s) too)
- Pacific / Antarctica boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.06 (flagged in 3 prior report(s) too)
Our Track Record So Far
We just started tracking outcomes for this report – check back here in a few months, once enough flagged zones are old enough to evaluate, for real track-record numbers.
This is a pattern-tracking report over real USGS data, not an earthquake prediction – no scientist can predict exactly when or where an earthquake will strike, and a “quiet” zone is not guaranteed to have a big one.
