What the record says
NCEI’s account, from the sources it cites.
(Located in Southeast Greenland.) Berninghausen (Reference #43) reports: A "tidal wave" about 50 or 60 feet above normal sea level demolished the crane and the rails used for hauling the supplies to the stores, as well as several of the boats which could not be brought to safety." His source is ICAO (Reference #1875). Only the year and month is mentioned.
