Trans. : Yes Distribution : 2002-2018 Refernce Levl: Heights are referred to the station tide staff zero, which is linked to land-based benchmarks. This reference zero is unique to this station and is not an official datum (chart, national, etc.) and is not relative to local tidal parameters, such as mean lower low water. See the Originators for benchmark descriptions, maps, and the geodetic levelling history. Comment : The old site 117A was discontinued in Aug 2002. Station 117B was established nearby but the series are not linked to the same reference zero. Tsunami signal evident in 12/2004. JASL Nov 2019 update replace 2016- 05 Sep 2017.
