Event #224 - Summary, and parameter estimates with source IDs Full references for Event # 224
Information on this earthquake is described in "The Central Cascades Earthquake of March 7, 1891"; by T.E. Johnson, R.S. Ludwin, and A.I. Qamar, in Washington Geology, V. 20, N. 1, pp. 36 -37 (felt area isoseismal map included). This earthquake was misidentified in previous catalogs as being felt only at Smith Island lighthouse. In fact, the earthquake was felt from Ellensburg to Seattle and Tacoma. The apparent focus was east of Seattle in the central Cascades, close to Mt. Si, with a total felt area of approximately 36,000 square km, therefore a magnitude of 5.0 (following the method of Toppozada, 1975)has been estimated. About a dozen accounts from newspapers both east and west of the Cascade Mountains and a diary entry from Monitor, Washington provide documentation for this interpretation. The "MISC" source cited as the preferred source above is the Johnson et al. article. Many catalogs contain an entry for an earthquake on March 8, 1890. Holden cites Plummer as his original source, but Townley and Allen correctly point out that the date given by Plummer was 1891 rather than 1890. We have attributed catalog entries for the March 8, 1890 earthquake to this March 7, 1891 earthquake. A search of newspapers found scant indication of other associated shocks, although there was a report of an earthquake felt at North Bend and Snoqualmie Pass on November 24 and another report, apparently from a single individual in downtown Seattle, of feeling an earthquake around 9 AM on the morning of Nov. 29th.

Event #230 - Summary, and parameter estimates with source IDs Full references for Event # 230
N. Puget Sound - It is seems that this earthquake was felt in the northern part of Puget Sound, but information is muddled, and several different times and dates are given. Holden says: "Port Angeles, Washington. Reports differ as to time, some claiming that the shock occurred at 4:10 A.M., others at 5 A.M. It is possible there were two distinct shocks. The direction of vibration was from northwest to southeast. Many people were awakened from sleep. Houses trembled and chinaware rattled (VI). Port Townsend: shock felt shortly after 4 o'clock a.m. Dishes rattled and sleeping people were awakened (VI)." The newspaper report of the Oregonian, repeated in the Spokane Review, seems incongruous, since it says that the event was felt at Portland and on the Elwha River "west of here". No newspaper reports could be found in the Washington Standard or the Seattle P.I. The Elwha River is at the northernmost part of the Olympic Peninsula. The handwritten report of the weather observer at East Sound on Orcas Island gives a time of "1:46 a.m"; and describes the earthquake as "NE to SW. 30 seconds." No other September earthquakes are described. The Chilliwack Progress says: "Westminster was visited by a sharp shock of earthquake last Wednesday morning about 4 o'clock. Many citizens were awakened by the shaking of their dwellings and the low rumbling sound which accompanied the shock. ... The shock was felt at Victoria nearly four minutes earlier, ...The shock was severe at Victoria and lasted seven seconds, but did no damage to property. " Wednesday would have been 9/23.

Holden cites an unnamed newspaper which is the underlying source for this event: "The first time an earthquake has been felt in Ashland for years was last night about 8 o'clock, when a distinct shock, though light and lasting only a few seconds, caused a general rattling of window panes in many buildings in town. The shock was not heavy enough to cause even timid people any alarm." I question Berg and Baker's assignment of intensity IV to this event. The newspaper article was not found, but this event is listed in the index of the Portland Oregonian.

Panes of glass were reported by Holden (1898) to have been broken in the Pysht hotel, but no mention of this was found in the Portland Oregonian or Seattle Post-Intelligencer newspaper reports which suggest that the shaking was most severe near Seattle, though the earthquake was also reported felt in Snohomish, around Bellingham Bay, in Port Townsend, Tacoma, and Olympia., but not in Portland. Milne says that this event was felt only slightly in Victoria. Reports of possible landslide-generated tsunamis - waves or swells were reported in Lake Washington, and in Puget Sound both in Seattle and in Tacoma in "Tsumanis Affecting the West Coast of the United States, 1806-1992". The index for the Spokane Spokesman Review says "Great alarm felt by Coast people when quakes are felt in Sound region SR 8th D 2, 91 6:4', but we could not locate this article on the microfilm. The handwritten report from the Aberdeen weather observer describes this earthquake as "slight", while the report by weather observer Riley Hoskinson on Bainbridge Island tells of a "smart rocking".

The shock lasted a few seconds but did no damage. The tremor terrified the townspeople, shook the windows of the houses, disturbed pictures and other household items. "Victorians were given a reminder of the dreadful earthquakes that have been doing so much destruction in Japan in shape of a slight shock about 3:30 Sunday afternoon.

Felt in Olympia. Newspaper reports in later years give a date of Feb. 21, probably due to that date being given in the index. An Rossi-Forel Intensity of VII was given for this event in early catalogs, but Townley and Allen considered that too high, and later catalogs use VI.

Event #246 - Summary, and parameter estimates with source IDs Full references for Event # 246
This is a sequence of foreshock, mainshock, and aftershock. The mainshock, on Feb. 2 at 2:55 AM was felt as far as Portland but was apparently strongest at Yakima and Fort Simcoe. Previous catalogs have not correctly described this sequence . Most state that this event was felt at The Dalles, where its intenstiy was reported as IV and the Oregonian reports: "Three distinct shocks of earthquake were felt here at 2:55 this morning. The vibration were north and south, and lasted about 4 seconds. A number of citizens were awakened by the shocks, and rushed into the streets in their nightclothes. In some residences the plaster was cracked and crockery rattled upon the shelves. No serious damage is reported.". The Woodward-Clyde and WPPSS catalogs have a separate entry for an event felt at Yakima, supposedly on March 5. We believe that these entries refer to the earthquake of Feb. 29. We have found a handwritten record from the weather observer at Fort Simco, in Yakima County, Washington, that reports: "Nothing special to notice except the earthquake on the morning of the 29th. It lasted about 30 seconds each shock. The middle shock was much the hardest . Windows and glassware were badly shaken and the plastering on some of the buildings was shaken off. It made a number of people sick to their stomachs.", and "3 shocks of earthquake at 2.00 - 2.55 and 3:15 AM of the 29th inst. The middle shock was the hardest . Glassware was shaken and one pane of glass broken". A similar description appears in the Spokesman Review of March 6, accounting for the erroneous date in some catalogs.

The MM intensity of VI given for Olympia by Earthquake History of the US seems overstated. The Seattle P.I. says :"Bad shocks felt in Portland, Tacoma, and Olympia. -- Portland, April 17. -- At 2:50 o'clock this afternoon two heavy shocks of earthquake were felt here. The shocks lasted about ten seconds each... Many persons became frightened when buildings began to tremble, and rushed into the street. No serious damage was done." the Washington Standard (Olympia) reports: "it was only severe enough to remind people of the mighty power that nature reserves for occasional display" and the Portland Oregonian states that a single slight earthquake was felt at Portland and that two shocks, the first making many buildings tremble, and the second scarcely perceptible, were felt at Tacoma. Some catalogs have two listings at this time, one for each city.

Event #257 - Summary, and parameter estimates with source IDs Full references for Event # 257
In Umatilla, The Oregonian reports: "... a succession of earthquake shocks spread fear and consternation among the inhabitants here. Buildings were violently rocked and the earth trembled quite perceptibly. One of the walls of a large stone warehouse fell with a crash. The remaining left tottering will have to be torn down. Mr Harns, the Union Pacific agent, was passing the building at the time and barely escaped being buried in the debris." The WPPSS document ( "WPPSS Nuclear Project No. 2, Final Safety Analysis Report, Volume 1, Amendment 18" September 1981) says: "This appears to have been an earthquake of very limited extent, because no felt reports from Pendleton itself nor any towns in the surrounding area were found in the search of newpapers in Pendleton and Milton-Freewater, Oregon, and Yakima, Walla Walla, and Spokane, Washington." The largest circular area about Umatilla that excludes Pendleton and Yakima has an area of 7,800 km2. The intensity-felt-area plot ... shows that a 7,800 km2 area is compatible with an intensity (MM) V-VI but is an order of magnitude less than the felt areas associated with intensity (MM) VII earthquakes. Consequently, the intensity rating of this earthquake has been reduced to (MM) VI ..". Likely very shallow and very close to Umatilla.

Volcanic Activity From the recollections of Edna Bolduc Anderson: "One day, in that July (1893), George and I were ... on a high ridge, just above the Big Mashel River, overlooking a canyon. ... The sky was clear. .... We glanced up and across to Mount Rainier. We saw great clouds of black smoke coming from her crater. It curled up, far into the clear, blue sky. I'll never forget that sight as I have only seen it the one time."

The actual date of this event is not known. The source appears to be a Washington Standard article dated 7/7/1893 that says: "Wenatchee experienced a genuine earthquake a short time ago, the first that has occurred for some time. Several years ago slight shocks were very frequent in the Wenatchee country. There were two very heavy shocks in the winter of 1872, which were felt very distinctly in this valley. That was the time that a large slice of the mountain split off and fell into the Columbia river and dammed it up for awhile." The 7/7 date is listed in the Woodward-Clyde catalog, and in the WPPSS documents.

Reports of this earthquake being felt in any place other than Olympia have not been confirmed. Newspaper reports from the Oregonian and from the Tacoma Morning Union say: "Olympia, Jan 14--A severe shock of earthquake was experienced here at 3:20 this morning." The Washington Standard (Olympia) says: "A slight shock of an earthquake was felt at 3:30 Sunday morning ..." Holden (1898) says "Olympia, Washington. Mr. Fred Plummer reports a disturbance at 3:25 a.m. A tremor lasting three seconds was followed after an interval of four seconds by a shock from south-southwest, and a slight tremor later. His seismograph at Tacoma barely showed the shock (I?, II?)". Holden also cites the S.F. Chronicle: "Vancouver, B.C. While the quaking continued, hanging pictures swayed slightly and crockery rattled on the shelves." The British Colonist for Jan. 15-17 was not available on the microfilm reel, and Milne reports that: " Newspapers make no mention of the event."
