Individual Event Report
Event #348 - Summary, and parameter estimates with source IDs                                           
The preferred location and magnitude of this event are from the dissertation of G.C. Rogers. Although quite widely felt in Seattle and south Puget Sound, there was no apparent damage and no aftershocks were reported.
The Seattle Post Intelligencer reports this earthquake felt in Seattle, Tacoma, Olympia, and Aberdeen. In Tacoma "Houses were rocked and crockery rattled and in some cases plaster fell off the walls." In Aberdeen: "Some persons reported that clocks were stopped and dishes on the table rattled.". The Oregonian reports that in Aberdeen "houses were shaken and the inmates ran out badly frightened", and in Olympia " Buildings were shaken so that occupants ran into the streets in alarm." The earthquake was reported *not* felt in Portland, Port Townsend, Whatcom County, and Everett.

Transcription: CITY IS SHAKEN
Earthquake Visits SEattle Early in the Evening
TWO DISTINCT TREMORS
Shock is All Over in One Second and People Have No Time to Get Frightened

Those who were on the second floors of their homes were treated to one of the Seattle's rarest visitors, an earthquake shock. Two distinct tremors were felt in succession, at 6:40 which shook strong buildings for just one second. It was over before any one had time to be frightened. As far as known the earthquake left no destruction in its path.
The shock was felt in all quarters of the city, with the exception, perhaps, of the bay and the shoreline. No reports of any seismic disturbance been noted in the shore area.
On the Queen Anne Hill, on the southern border of Lake Union and in the southern suburbs the shock was most apparent. Several who noticed the undulation say it proceeded in a north and south direction. Although not many people felt the quake, those who felt said it was distinctly perceptible. In one dwelling in the Anne Hill the shock was felt by a resident on the first floor of his house, and by his wife on the second floor.
Out on the Eastlake avenue a house which the owner says, the rumble of the passing car never disturbs, yielded to the unsteady attack of the earthquake and shock. The shock were however, nowhere strong enough to knock a slight object over.
HOUSES ROCK IN TACOMA
A distinct earthquake shock was felt at 6:23pm today. Houses were rocked and crockery rattled and in some cases plaster fell off the walls. Many people claimed that the noise resembled an explosion similar to the one made by a mine explosion.
In the large office buildings the shock was more pronounced than in their places. Other parts of the city swayed perceptibly. People here believe that earthquake may precede a volcanic eruption of Mount Rainier. Many were firightened and felt uneasy about spending the night in their houses.
FLEE TO THE STREETS
Occupants of Olympia Buildings Are Alarmed by Shock
OLYMPIA, March 13. – (Special.) – An earthquake shock was felt here at 6:21 o’clock this evening. In the larger buildings of the city the shock was rather violent, while on the streets it was not so distinct.
Occupants of the larger buildings fled to the street in alarm when the shock occurred, but returned a few moments later with an abashed air.

IS FELT AT ABERDEEN
Houses Shaken and Clocks Reported Stopped
ABERDEEN, March 13. – (Special.) – Three distinct shocks of earthquake were experienced here about 6:25 o’clock tonight. In some localities houses ere shaken, and the inmates ran out, badly frightened. Some persons reported that clocks ere stopped and dishes on the table rattled.
A similar shock was experienced in the city ten years ago.

RUMBLING AT EVERETT
Citizens on the Streets Claim to aHave Heard It.
Everett, March 13. (Special} About 9 o'clock this evening several persons on the Hewitt Avenue claim to have heard a low noise resembling thunder. It lasted but a moment, and was not accompanied by any perceptible shock.
The sky was clear at that time, and the sound seem to come from the earth.

NO SEMBLANCE OF SHAKE
Shock Unperceived in Lower Sound Region
PORT TOWNSEND, March 13. – (Special.) – This portion of Puget sound escaped any semblance of a trembler. Neither atmosphere nor water conditions were disturbed in the slightest, although clouds of inky darkness hung low over the adjacent landscape.

Unnoticed at Whatcom
WHATCOM, March 13. – (Special.) – No earthquake shock was felt here today.
People here are not through wondering about the earthquake which took place Friday. The shock, or shocks, were very emphatic here, and everybody who happened to be in buildings, especially in upper stories, felt the phenomenon. The greatest diversity of opinion exists concerning the earthquake. Some contend it was accompanied by a deep, subterraneous noise which appeared to pass under the city. Others did not hear the noise, but felt two shocks. Indeed there are many who claim there were three distinct earthquake shocks Friday, one about 3 p. m. and the other two quickly following one another about 6:23 p. m.

SEATTLE PEOPLE REPORT TWO PERCEPTIBLE SHOCKS. Other Puget Sound Cities Feel the Jar at 6:30 Last Evening-Movement Is Eastward.
SEATTLE, March 13.--(Special.)--Seattle caught two slight shocks from the seismic movement that struck through Western Washington this evening. The tremor appears to have been noted by but few people. These agree that the two shocks came very close together betwen 6:35 and 6:40. No one reports noting a movement of more than very faint perceptibility.
The disturbance appears to have extended from the Gray's Harbor country in a generally eastward direction to the Cascades. Aberdeen reports three distinct shocks about 6:25. Houses were considerably shaken and for a few moments the people were much alarmed. Olympia received one shock at 6:21. Tacoma felt several beginning at 6:23. These reports indicate the course of the disturbance. North of Seattle no movement was felt. Everett did not quake, but anxious, perhaps, to be noticed in this connection, reports a loud rumbling noise at 9 o'clock.
Port Townsend and Whatcom claim nothing more serious than cold and gloomy weather.
OLYMPIA BUIDINGS SHAKE. Shock Lasts Nine Seconds-Slight Rumblings Are Heard.
OLYMPIA, Wash., March 13.-An unusually perceptible earthquake was felt in this city at 6:25 this evening. Buildings were shaken so that occupants ran into the streets in alarm. The seismic waves seemed to travel from northeast to southwest and the principal shock was preceded by a tremor of a few seconds and followed by another slight tremor, the entire disturbance lasting nine seconds. A slight rumbling was also heard.
PEOPLE BADLY FRIGHTENED. Aberdeen Inhabitants Rush Out of Their Houses-Three Shocks.
Aberdeen, Wash., March 13.-(Special)- Three distinct shocks of earthquake were experience here about 6:25 o'clock tonight. In some localities houses were shaken and the inmates ran out badly frightened. Some persons reported that clocks were stopped and dishes on the table rattled. A similar shock was experienced in this city ten years ago.
Conditions Were Propitious
PORT TOWNSEND, Wash., March 13.- Although every condition was so propitious as to occasion comment on the probability of an earthquake at sundown tonight, this portion of Puget Sound experienced no perceptible shocks. As night fell, low black clouds met the view in every direction, and the atmosphere became still and threatening.
Several Shocks at Tacoma.
TACOMA, March 13.-Several distinct seismic shocks were felt in different sections of the city about 6:23 tonight.

Transcription: Campus Shaken By Big Tremor
Endures Seven and a Half Minutes and Alarmed Professors Dismiss Classes.
Movement Is Recorded
Entire Puget Sound Region Affected but Disturbance Is Purely Local.
For seven minutes and thirty seconds yesterday afternoon the university campus experienced earthquake shocks of an alarming though not necessarily dangerous character. The seismograph in the Science Hall recorded the first movement at thirteen minutes to 4 o'clock. The movement registered three-quarters of an inch upon the dial, the markings of which, however, are magnified ten times. No damage was done on the campus, although several professors, becoming alarmed, dismissed their classes, but in the city windows in the large office building were broken and occupants of offices frightened. For some time after the shock started residents of outlying districts kept busy the telephones of possible sources of information.

Local Disturbance.
The fact that the waves as recorded on the instrument are straight and near together, and that they are longer from east to west than from north to south, said C.H. Wheelon, assistant in the department of geology, who is in charge of the instrument, "would seem to indicate that the disturbance is purely local in character, very similar, no doubt, to the earthquake experience is Seattle in 1903. It is exceedingly difficult to account for this movement of the earth. This region is out of the earthquake zone. It might possibly be due to some change taking place in the nearby mountains." The Italian earthquake disaster was recorded by the seismograph during the holidays. The first indications on the dial were noticed between 8 and 9 o'clock in the morning of December 27, 1908. The violent shocks lasted twenty-six minutes according to the register, although the entire movement occupied a little over two hours.

*Felt area from "Earthquake History of the United States" by Coffman and
von Hake (1973).

1)Magnitude in the Canadian Earthquake Data File.

2)Calculated using Toppozada's (1975) relationships

5) Comments on Revisions of Some Key Earthquakes (Figure 6)

a) March 16, 1904
In the Canadian Earthquake Data File the epicentre for this event was located on the west
side of the Olympic Peninsula and it was assigned a magnitude of 6. in "Earthquake History of
the United States" it is given the location of Victoria, B.C. and assigned an intensity value of V.
A study of felt levels from newspaper reports suggests the earthquake has an epicentre along the
west side of Puget Sound, south of Port Townsend and that the magnitude is about 5. The
confirmation that this earthquake was not near the west coast of the Olympic Peninsula is
important as no large earthquakes have yet been located along the coast.

b) January 11, 1909
Felt reports from newspapers limit this epicentre to the San Juan Islands region where
several instances of damage occurred. Felt information also clearly shows that the size of the
isoseismal maps is between that for the 1965 Seattle earthquake and the 1976 Gulf Islands
earthquake (Figure 7). The magnitude is about 6 according to Toppozada's (1975) felt area
relationship. Lack of aftershocks and lack of higher intensities in the epicentral region suggest
this event belongs to the deeper suite of earthquakes. This event is significant because it
points out that large earthquakes in the deeper suite can also occur north of Puget Sound.

c) December 6, 1918
This earthquake has several epicentres in the literature which are shown in Figure 8.
Investigations with the set of P arrival times listed in the ISS place the epicentre on Vancouver
Island near the west coast, south of the present town of Gold River which did not exist in 1918.
Because of the quality of 1918 arrival times this epicentre has an uncertainty of the order of + 50
km. Felt information collected by Dennison (1919) and supplemented by newspaper
investigations suggest the magnitude of 7 (Ms) calculated by Gutenberg and Richter (1949) is
correct.

d) February 9, 1928
Felt information and a 100 mile distance issued from the Victoria seismograph station (VGZ),
presumably from the S-P interval, indicates the earthquake was in the vicinity of Barkely Sound
and had a magnitude of about 5-3/4. This event was in the Canadian Earthquake Data File but
was located in the Strait of Juan de Fuca with a magnitude of 3.7. It is significant that an
earthquake of this size occurred in the Barkely Sound region as there have been no events
above magnitude 4 in that region since 1928.

e) September 17, 1926 and May 7, 1927
Both of these events were assigned epicentres by the ISS at the location previously
calculated for the epicentre of the December 6, 1918 earthquake (Figure 8). Because of the
proximity of the cities of Nanaimo and Victoria and the distribution of population close to the ISS
epicentral region, these earthquakes could not have been located there as they would have been
felt. With the data listed in the ISS and felt reports they were located elsewhere. The 1927
event occurred in the vicinity of Brooks Peninsula on Vancouver Island and the 1926 event
occurred on the mainland north of Vancouver (see Appendix 1).

It would seem from this and the fact that at many intervening points shocks were felt; that there must have been a grand succession of pyrotechnic disturbances deep down in the bowels of the Earth, covering a period of several days.
