SWARM DEVELOPING
The Alaska-Aleutian zone continues to activate across multiple segments. The Akhiok cluster (Kodiak Island) now totals 12 events with three M3.9. A significant M4.0 struck 196 km SW of Nikolski in the western Aleutians — confirming the model's indicated westward migration of activity. New interior seismicity at Chase (M3.1, M3.0) and near Denali National Park (M2.7) adds depth to the regional activation. A M3.6 at Ninilchik on the Kenai Peninsula extends the active zone northeastward.
FORECAST OUTLOOK
The system identifies six days of elevated Alaska targeting in February: Feb 8 (46.9%), Feb 9 (30.2%), Feb 12 (41.6%), Feb 16 (19.2%), Feb 24 (62.7%), and Feb 28 (20.1%). Current prediction window runs through Feb 13 for M4.5+ events. A secondary targeting peak arrives Feb 11-12 via the secondary axis, followed by the strongest Alaska targeting of the month on Feb 24 at 62.7% — the dominant zone globally that day.
SUBZONE MIGRATION
The M4.0 at Nikolski confirms the model's indicated westward migration: Feb 8 concentrated on AK-Central (42.8%), and now the western Aleutians are activating. Feb 12 targeting shifts further to AK-West (36.0%), and Feb 24 loads AK-West at 58.5% — the strongest Alaska targeting of the month. Simultaneously, a 27-event earthquake swarm erupted in the U.S. Virgin Islands today (M2.9-M4.4), which the model links to sustained Caribbean zone energy detected within the 30-day signal window. The USVI zone shows 56.2% targeting on Feb 14, suggesting the Caribbean swarm may intensify.
