Felt in Victoria, Milne says: " three shocks were felt. The first two followed each other by a few seconds, and they were followed by another in 10 minutes. Bottles fell off shelves and some people ran out of doors. Br. Col." The Oregonian reports a "slight earthquake" at Victoria. The only newspaper article found for this event was in the Oregon Statesman. A review of the British Colonist covering this time period failed to turn up additional information.

It was accompanied by a hoarse thundering rumble, and lasted for about thirty seconds. ...So frightful was the commotion of its quick and awful rockings as to make it a moment of great suspense as to whether the beholder would be buried with the log shanty, which cracked, rolled and tottered around him".

Newspaper accounts indicate that this event was felt quite strongly and awakened many in Victoria. Followed by a probable slight aftershock felt in Victoria between 5 and 6 AM. The shaking was reported to cause considerable fright and crockery breakage at Port Townsend and Whidbey Island and was strong enough to wake sleepers in Olympia. The newspaper from New Westminster, on the B.C. mainland, does not indicate that it was felt there. This event was cataloged by Milne.


The Oregonian and Oregon Statesman were searched, but no nformation on this event was found in either.

Newspapers report that this earthquake was felt at both Victoria and New Westminster, B.C., with the shock being stronger in Victoria, where it was described as lasting 10 seconds (Holden's catalog gives the duration as 15 seconds and calls it the "severest shock on record."). toppling one chimney, cracking plastering all over, and throwing bottles and crockery to the floor in several shops. Henry Roeder, an early settler at Bellingham, wrote in his journal that he feared his house would fall off its foundation, although the time he reports is about 45 minutes later than times reported in Victoria. No report of the earthquake being felt was noted in a scan of weather reports from Neah Bay.

The New Westminster paper also reports that the large trees were broken on an island near Plumper Pass, probably referring to a location close to Discovery Island, about 5 km east of Victoria's Oak Bay

Subsequent reports in the British Colonist about a week later suggest a massive rockfall from Mount Baker. The April, 1895 weather records of James Swan at Neah Bay included an additional clipping related to changes in appearance of Mount Baker, and Swan says that he included sketches of the appearance of the mountain before and after.

Many catalogs list this earthquake, and indicte a maximum intensity of VI, and list the time incorrectly as evening. Newspaper accounts all agree,that the earthquake was in the morning.

Event #55 - Summary, and parameter estimates with source IDs                                            Full references for Event #  55
This earthquake appears to have been felt only in Victoria, and the accounts from the Victoria papers are terse: "A sharp shock of an earthquake was felt in this city a few minutes after 9 o'clock last night."
The account from the Pacific Tribune of Olympia is considerably more florid: "An Earthquake.-- Our Victoria exchange mentions a severe shock of an earthquake which occurred in that city on the 29th ult. Two distinct shocks were felt, a few seconds intervening. Brick and frame buildings trembled violently, and in some instances the plastering was cracked. The oscillation was from North to South and lasted about half a minute."
Earlier catalog entries for this event have suggested it was larger. Holden (1887) cites Fuchs: "1865. August 25; 9 p.m. Heavy shock at Vancouver Island, lasting two minutes; later two more shocks.-Fuchs." and Holden (1898) adds a reference to Plummer (Publications Astronomical Society of the Pacific, V. 8, p. 78, 1896) who made the assignment of RF Intensity IV at Victoria. Bradford (1935) gives an RF Intensity of VI, which is repeated in Townley and Allen (1939) , who suggest that it was probably felt in Washington. Earthquake History of the United States (1973) also gives an intensity of VI ( but MM), and says "Probably felt strongly on Olympic Peninsula, Wash ."
Unless local reports from Vancouver Island can be found, it seems reasonable to conclude that this is a much smaller event than previously cataloged.

February 17; 'The Klamath River, fifteen miles above the Jacksonville road, was suddenly raised, exposing its bed, while a hill on its bank sunk away to a level plain: on one side of the hill, where it separated from the mainland, it left an abrupt bluff. The river channel was immediately changed, the water running around where the hill had been standing. Bob Whittle, and others, witnessed the phenomenon, and gathered large quantities of fish, that were left in the old bed, when the water drained off.'-B.Ms.-Quincy Union, March 10, 1866.Yreka Journal."

Reported felt to the east as far as Umatilla, but not felt in Portland, this earthquake alarmed many citizens at the Dalles.where "The tinware and stoves in the store of Bunnell & Miller made quite a din" (The Oregoninan). Most earlier catalogs listed this event as occurring in December. The 11/24 date is given in several newspaper accounts and I surmise that only a single event occurred.

False Earthquake Report Although there is a widely published description of an earthquake on this date, it is best described as the "Famous earthquake of Fort Klamath that didn't take place". This is *NOT* a real earthquake! As Townley and Allen say: "... a long letter .... gives all the lurid details of a terrible earthquake. It is now known that ...this account came from the fertile imagination of a soldier by the name of Warren, stationed at Fort Klamath, who evidently was seeking diversion and amusement during the dull winter months." An Oregon Sentinal article of May, 1867, also recognized this account as a hoax.

When the famous earthquake of Ft. Klamath didn't take place, a prominent citizen of Ashland felt a shock that quite unsettled his nerves, and as no shock was perceptible in this end of the valley on Saturday night, we are inclined to think some people were troubled with night-mare or indigestion."

A House was moved a number of inches from its foundation." (Weekly Intelligencer (Seattle) Monday Feb 17,
1868 p 3 col 2)

There has been some confusion as to the date of this event. Newspaper accounts place the date on May 20, and describe the earthquake as a "smart shock" in Mukilteo and also felt in Tulalip. Holden (1887) gives a date of May 30. Holden cites an account in the San Francisco Bulletin and calls this event "severe". Other catalogs stem from Holden. Rasmussen lists what is probably this event with an apparently erroneous date of June 20.

Previously uncataloged. From the account of the 1868 surveying party of Daniel G. Major on OR-CA border: He reported several earthquakes, "that of August 27th, at 8.45 a.m., being so violent as to stop the box chronometer and disturb the instrumental adjustments."

A small earthquake reported felt only in Port Townsend. There has been some confusion over the date of this earthquake. The Port Townsend paper reports it on Feb. 11, while papers in Olympia and Seattle and catalogs give it as the 18th. The Port Townsend paper says: " It lasted several seconds and was quite perceptibly felt. Indeed, it created considerable alarm in the minds of some for the terrible experience of San Francisco is not yet forgotten."

This may be a foreshock to June 27th 1869 earthquake. This earthquake, felt in Olympia on Sunday afternoon 6/20, was severe near Mount Rainier, and caused a landslide into the Cowlitz River, where turbidity was seen in the Cowlitz at Olequa from Monday through Wednesday. The British Colonist states that this earthquake was not felt in Victoria. Many reports include this earthquake when discussing larger quakes a few days later.

Possible foreshock of event on June 17th. This earthquake was strongly felt in the Puget Sound, but was NOT felt in Victoria. The Pacific Tribune (a weekly paper from Olympia) says: " ... not only convinced the most skeptical, but ... terrified all who are in the least inclined to timidity. At a few minutes before five o'clock, .... a shock was felt which awaked from the soundest slumbers nearly all who had not yet arisen, and seriously alarmed those who were astir at that hour, many of whom felt an earthquake then for the first time. Some who were sleeping precipitately arose from their beds; others were unnerved to such a degree as to be incapable of moving for some minutes. All were more or less startled." Newspapers appear to report this event with different dates.

The strongest and most widely felt of the four events reported felt in Olympia between June 20 and 27th of 1869, this earthquake was reported felt from Victoria, B.C. to Astoria, OR, though there is no mention of its being felt in Portland. People in Olympia and Seattle ran to the streets, and dishes were broken in Seattle. In Victoria, porcelain vases and chinaware were "thrown upon the floors and broken". No other damage was reported, although the Pacific Tribune states that the waters near the shores of Puget Sound "swarmed with fish of all varieties, seemingly desirous of escaping from the deep to terra firma", and the Olympia Transcript reported a fish kill sighted from "Jeal's Point" 15 minutes *before* the earthquake was felt.
