Abstract

Seven great earthquakes, or earthquake series, probably ruptured the southern Washington part of the Cascadia subduction zone in the past 3,500 years. Each earthquake was probably of magnitude 8 or larger. The earthquakes define six recurrence intervals that average about 500 years. The longest interval, about 700-1300 years, was followed by two of the shortest, which together lasted less than 800 years. Another long interval, 600-1000 years, ended with an earthquake 300 years ago.

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.
