Abstract

We show the first real-time record of the turbidity current associated with a great earthquake; in this case with the Mw 9.0, 2011 Tohoku-Oki event.Turbidity current deposits (turbidites) have been used to estimate earthquake recurrence intervals from geologic records.Until now, however, there has been no direct of evidence for the large-scale earthquake in subduction plate margins.After the 2011 Tohoku-Oki earthquake and tsunami, an anomalous event on the sea floor consistent with a turbidity current was recorded by ocean bottom pressure recorders and ocean bottom seismometers deployed off Sendai.Freshly-emplaced turbidites were collected from a wide area of seafloor off the Tohoku coastal region.We analyzed these measurements and sedimentary records to determine conditions of the modern tsunamigenic turbidity current.We anticipate our discovery to be a starting point for more detailed characterization of modern tsunamigenic turbidites toward their identification in geologic records.

  • The AD 2011 Tohoku-oki earthquake remobilized young fine-grained surficial slope sediments enriched in organic matter, which was eventually deposited in the more than 7 km deep Japan Trench.

    “In the hadal Japan Trench, the AD 2011 Tohoku-oki earthquake remobilized young fine-grained surficial slope sediments enriched in organic matter, which was eventually deposited in the more than 7 km deep trench (Arai et al., 2013; Oguri et al., 2013; Strasser et al., 2013; Ikehara et al., 2016; McHugh et al., 2016; Kanamatsu et al., 2017; Bao et al., 2018; Kioka et al., 2019; Molenaar et al., 2019”

    The Introduction and Triggering Mechanism sections describe a turbidity current associated with the 2011 Tohoku-Oki tsunami, and the Characteristics section reports newly deposited, fine-grained sediment on the continental slope. Our copy does not establish that the remobilized sediment was young or enriched in organic matter, or that it was deposited in the Japan Trench at depths greater than 7 km; the reported instrument depths extend to 5700 m.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
