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 October 13, 2026.
Zones With More Earthquakes Than Usual
- Nazca / Panama boundary: 30 earthquakes in the last 14 days, releasing about 86.72x the seismic energy this zone usually releases in two weeks
- Nazca / Panama boundary: 59 earthquakes in the last 14 days, releasing about 78.21x the seismic energy this zone usually releases in two weeks – mostly from one large earthquake and its aftershocks
- Nazca / Panama boundary: 23 earthquakes in the last 14 days, releasing about 47.15x the seismic energy this zone usually releases in two weeks
- NB/SS: 4 earthquakes in the last 14 days, releasing about 19.89x the seismic energy this zone usually releases in two weeks – mostly from one large earthquake and its aftershocks
- PA/WL: 2 earthquakes in the last 14 days, releasing about 19.77x the seismic energy this zone usually releases in two weeks – mostly from one large earthquake and its aftershocks
- PA/SS: 3 earthquakes in the last 14 days, releasing about 19.13x the seismic energy this zone usually releases in two weeks – mostly from one large earthquake and its aftershocks
Zones That Have Gone Quiet
- India / Somalia boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.08 (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 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 1 prior report(s) too)
- Timor / Australia boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.06
- Pacific / Australia boundary: only 0 earthquakes in the last 14 days, vs a usual average of about 0.06
- AU\PA: only 0 earthquakes in the last 14 days, vs a usual average of about 0.04
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.
