'Earthquake History of the U.S' says: "Northwest of Cape Mendocino. Large submarine shock, but so far from land that the greatest intensity on shore was VI at Eureka. Felt at San Jose, northward into Oregon, and in northwesten Nevada. Magnitude 7.6." Another reference, 'The San Andreas Fault System, California, Chapter 6: Earthquake History, 1769-1989, by William L. Ellsworth, USGS Professional Paper 1515. 1990', says: "This event was well recorded throughout the world."
This earthquake was ** very** widely felt. Over a dozen weather observers in Oregon reported to MWR. The highest Oregon intensities reported in the MWR were RF Intensity V, at Central Point, Brookings and Oakridge, Oregon.
Townley and Allen say: "Southern Oregon. A severe shock with its epicenter at sea off Cape Mendocino, California, was felt in southern Oregon on January 31. It was reported felt in Ashland, Grants Pass, Canyonville, Roseburg, Marshfield, Medford, and Eugene. One report says that the shock was also felt in Klamath Falls."
The Oakland Tribune reports: "...At Eureka the temblor, which was of considerable duration, stopped clocks and broke dishes. At Canyonville, Oregon, beds rocked and windows were broken. Canyonville is about 225 miles south of Portland and about 125 miles north of the California line. At Roseburg, Oregon, the entire city was awakened. It was also felt at Eugene, at Portland, Seattle and other northern points. So severe was the shock that the needles of the seismograph instruments at the University of California, at Seattle and at Spokane were lifted from the recording drums. .... Telephone reports from Weaverville, Yreka, Dunsmuir, Fall River, Mills, and Weed, all in the extreme northern part of California, were that the quake had been felt, in varying degrees of intensity. It also was felt at Klamath Falls, Ore. No damage was reported." |
