What the record says

NCEI’s account, from the sources it cites.

Note: Reference #99 states the epicentre is from felt effects. So the Sept 10 earthquake was not from instrumental recordings but felt information. So the date might have been wrong. Reference #414 says that the report on 10 Sept event actually refers to the 17 Sept event. Thus, there may have only been one earthquake (and tsunami) either on Sept 10 or (more likely) on Sept 17.

1900, September 10, 21:30 UTC, 4 S, 152 E, shallow depth, magnitude 6.8 MS. Remarks from Anonymous, 1902: 'A severe earth tremor was felt in the Rabaul area at 8 a.m. of 12th September 1900. European homes were damaged, and some lightly built houses collapsed. The shock was accompanied by a tidal wave which did not cause any damage. The tremor appeared to originate near the volcanoes "Father and Son". Minor tremors persisted throughout the day. Date reported should be 11th - Author. (reference #99)
