Evidence of The Earthquake
Evidence supporting the occurrence of the 1700 earthquake has been gathered into the 2005 book The Orphan Tsunami of 1700, by geologist Brian Atwater and others.
The evidence suggests that it took place at about 21:00 on January 26, 1700 (NS). Although there were no written records in the region at the time, the earthquake's precise time is nevertheless known from Japanese records of a tsunami that has not been tied to any other Pacific Rim earthquake. The most important clue linking the tsunami in Japan and the earthquake in the Pacific Northwest comes from studies of tree rings (dendrochronology) which show that red cedar trees killed by lowering of coastal forests into the tidal zone by the earthquake have outermost growth rings that formed in 1699, the last growing season before the tsunami. Local Indigenous American oral traditions describing a large quake also exist, although these do not specify the date. There are many areas in the Pacific Northwest with drowned groves of trees that also show evidence of the earthquake.

Famous quotes containing the words evidence of, evidence and/or earthquake:
“However backwards the world has been in former ages in the discovery of such points as GOD never meant us to know,—we have been more successful in our own days:Mthousands can trace out now the impressions of this divine intercourse in themselves, from the first moment they received it, and with such distinct intelligence of its progress and workings, as to require no evidence of its truth.”
—Laurence Sterne (1713–1768)
“Washington has seldom seen so numerous, so industrious or so insidious a lobby. There is every evidence that money without limit is being spent to sustain this lobby.... I know that in this I am speaking for the members of the two houses, who would rejoice as much as I would to be released from this unbearable situation.”
—Woodrow Wilson (1856–1924)
“Through the din and desultoriness of noon, even in the most Oriental city, is seen the fresh and primitive and savage nature, in which Scythians and Ethiopians and Indians dwell. What is echo, what are light and shade, day and night, ocean and stars, earthquake and eclipse, there? The works of man are everywhere swallowed up in the immensity of nature. The AEgean Sea is but Lake Huron still to the Indian.”
—Henry David Thoreau (1817–1862)
