What the record says
NCEI’s account, from the sources it cites.
A shock lasting 3-4 seconds was felt at Skagway, Klakuan, at the Point Sherman lighthouse in the region of Lynn Canal. Many residents woke up. The dishes rattled, lamps swayed, and the pendulums of clocks stopped. The shock was accompanied by a faint rumble. It was registered by the seismograph at Sitka. A seaquake was felt on a ship situated 7 km (4 miles) north of Haines, and a small temporary change in the water level was noticed. [These were probably seiches. Judging by the amplitude of the shocks at Sitka, its magnitude can be estimated at 5 1/2 +/- 1/2] (Reference #415).
