An earthquake has occurred; a tsunami is not expected.

NWS National Tsunami Warning Center Tsunami Information Statement Number 1, Sep 3, 2026

Primary sources: USGS eventpage us7000tdvt and the NWS NTWC Tsunami Information Statement Number 1. Coordinates and magnitude are USGS products; the no-tsunami line is NTWC.

Doom Signals does not treat a single Aleutian M6.3 as evidence of Earth Core Dynamo Oscillation. ECDO remains a hypothesis, not proven science. This note is limited to the named reviewed event and the official tsunami statement.

  • Event: USGS us7000tdvt M6.3
  • Place: 84 km SSW of Nikolski, Alaska
  • Official coords: 52.2579, −169.4088

Why it matters

Fresh Sep 3 UTC reviewed USGS M6.3 (us7000tdvt) with an NTWC no-tsunami statement — a newer ≥M6 geophysics pin than the Sep 2 South Sandwich M6.2 board item, without inventing ECDO proof.
