"SHOCK OF AN EARTHQUAKE
"We have received the following from a rural correspondent:--'The
shock of an earthquake was felt on Thorne's Creek, three miles east of
Fort Langley, on Sunday the 28th of Feb. last at 7 1/2, in the evening. It
was accompanied by a hoarse thundering rumble, and lasted for about
thirty seconds. The sky was at the time clear and brilliant and the
atmosphere calm and mild. 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, in a conglomerated mass of hetrogenious ruin.
Its course was across the Creek, from north to south.--Ib'
"(Query. Has Artemus Ward strayed up to the neighborhood of Thorne's
Creek?--Ed. ) "

"PHENOMENA ON SUNDAY EVENING
"Between 7 and 7:30 o'clock on Sunday evening there occurred a
remarkable stillness in the air and an oppressive, heated condition of
the atmosphere which forbade the slighest suspicion of frost. Worshippers
at the churches felt the air grow oppressively warm and not a few laid
aside their wrappers and overcoats. This 'heated term' continued until
7:35 o'clock when a veritable earthquake shook the city. The shock came
with a rush and a sweep similar to that of a heavy gust of wind. The
buildings vibrated slightly and gas-burners moved rapidly from side to
side, lights flickered and flared for a few seconds, and then everything
settled back to a state of accustomed steadiness. -In a few moments the
atmosphere grew as suddenly cool as it had before become warm, and by
8:15 o'clock a cold current of air was flowing from the Northwest."

"Westminster and Nanaimo papers report a slight earthquake at 15
minutes to 11 o'clock Wednesday night which rattled doors, windows and
crockery. The shock, if felt at all, was scarcely perceptible here."

Victoria Daily Colonist, Victoria, B.C., April 5, 1877
"At about 4 o'clock yesterday morning a slight tremor of Mother
Earth was felt by several persons who happened to be out of bed at the
time. But the motion was so slight as to cause some doubt as to its
real character. At 22 minutes to six o'clock-one hour and 38 minutes
later on-there was a violent and unmistakable disturbance of the sublunary
sphere. The shock seemed to travel from east to west. -It was accompanied
by a loud rolling sound as if of a heavy cart being driven rapidly
through the streets, and ended with a bang! like the report of a cannon
fired a mile or two away. The force of the shock and accompanying noise
and clatter woke nearly everyone who chanced to be asleep at the time.
Houses rooked, crockery rattled, and doors and windows shook violently.
In some houses crockery was thrown from the shelves and broken. In
Langley & Co.'s drug store a number of glass chimnies were shaken from
the shelves and smashed. We have heard of no damage to persons or
dwellings. From New Westminster we hear that the shock was not felt
there."

"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.
As nearly as can be ascertained the earthquake occurred at precisely
8:44 o'clock, and it lasted nearly 10 seconds. The shock was felt at
Victoria nearly four minutes earlier, which indicates that the earthquake
travelled in a northeasterly direction. The shock was severe at Victoria
and lasted seven seconds, but did no damage to property. Reports of
this unusual occurrence from other portions of the Province will be
awaited with interest."

"An earthquake shock was felt at Port Haney Sunday afternoon about
3:30. 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. Buildings shook, glass ware threatened to
fall, ladies screamed and turned pale, but nothing was damaged in any
way. "

"RECENT EARTHQUAKE
"Why the one recently felt here was not recorded by seismograph.
"For the benefit of those who thought they felt an earthquake on
the afternoon of Sunday a fortnight ago, a Colonist representative has
obtained the following information from the meteorological office upon
the subject: The photograph traced from the seismograph installed in
the basement of the old customs offices, recorded no Less than five
distinct shocks during the week ending Saturday, November 24. The first
shock occurred at 6:28 a.m. on Sunday the 18th, and from the form of
vibration may have originated some hundreds of miles away. The next
occurred at 7:48 and 7:51 A.M. of the same day as two sharp but small
vibrations, and from their appearance seem of local origin Strange (at
least to the uninitiated) the shock felt in the afternoon did not cause
the instrument to move, though it has been conclusively proved that this
instrument is so sensitive that it is constantly recording earthquakes
that occur at all quarters of the globe.
"The cause for this is that the recording part of this instrument
which consists of a long horizontal broom, is suspended pointing exactly
south; therefore should the earthquake waves travel east or west they
cause the broom to swing; where as, as sometimes happens, these waves
travel directly from north or south, when as they pass under this station,
they can only tip the broom up and down, but not sideways. -It so happens
that the Sunday afternoon quake did travel from north or south, for from
further information, it is learned that it was distinctly felt on the
Gorge Road, at the Pacific club, on fort street, and in a house on the
Dallas road., near Menzies street, the time being about 2 o'clock before
the close of the week, no less than three more shocks were recorded and
none of these were of local origin, on the contrary they were of a type
of vibrations whose birth place was probably the other side of the
world."

"Nanaimo, B.C. Oct. 7 - Two severe shocks of earthquake following
each other in quick succession were felt here at 11:25 last night. The
first shock was preceded by the low, rumbling roar, terminating in a
sharp shock of 10 seconds duration. Buildings trembled, whole dishes
rattled and tumbled to the floor in every house. The shock was the most
severe ever experience here. On Commercial St. the shock was very
severe. Mr. Albert Booth, the night operator at the CPR telegraph
office was busy taking the report, when suddenly he was almost wrenched
from his chair by the force of the shock."

"EARTHQUAKE SHOCK AT THE COAL CITY
"(Special to the Times)
"Nanaimo, B.C. Oct. 3 - An earthquake tremor lasting about two
seconds was experienced here this morning at 12.38 1/2,."

"EARTH TREMOR IS FELT IN VICTORIA
"Shock of one second's duration was experienced on Sunday afternoon.
"An earthquake of about one second's duration was felt in the city
at 1 P.M. on Sunday, the movement being either from north to south or
vice versa. The meteorological office seismograph did not register the
shock on account of the short duration of the movement and the fact that
the local instrument does not register earthquake activity except in the
line between east and west or vice versa. The shock was, however, felt
by a number of persons, especially in the vicinity of Cedar HIll where
it was most pronounced.
"In confirmation of the individual reports concerning a period of
earth unrest received from points adjacent to the city, a telegram to
the Times from Ottawa today announces that: 'The seismograph at the
Dominion Observatory at 12:15 P.M. yesterday recorded a more severe
earthquake movement than it did of the Jamaica earthquake."'

"EARTHQUAKE FELT IN BELLA COOLA
"Bella Coola, Jan. 20 - On Saturday, January 4, at 8 P.M. there was
a very distinct shock felt, lasting about 15 seconds; felt principally
in the lower part of the valley. On Saturday, the 5th, the tides were
very high indeed, higher in fact than for the past 12 years; no doubt as
a result of the earthquake shock. No damage was done."

"QUAKE FELT AT NELSON
"Doors at Provincial Jail Were Shaken last Week.
"Nelson April 4 - W.R. Jarvis, warden of the Provincial Jail
believes that an earthquake tremor was felt in Nelson last week. There
were two occasions on which the cell doors and all the movable iron work
rattled without any apparent cause.
"No train was passing on the track below at the time, and that is
the only circumstance that has ever previously caused a rattle of the
bars in the jail. The guards and prisoners both noticed and commented
on the incidents at the time."

"EARTH TREMORS REPORTED
"Two slight earth tremors were noticed here yesterday. The first
occurred in the morning and was reported by several people from Rockland
Avenue. The second was noticed about 2:30 P.M. and was especially felt
at CoLwood. It was stated yesterday to be due to changed barometric
pressure consequent on the high temperatures prevailing for the last few
days."

"EARTHQUAKE CRACKS IN SURREY SPUD FIELDS
"Strangest story from the potato fields comes from T. Longstaff,
Cloverdale, who reveals that the dyV spell has developed long and deep
'earthquake' cracks in his soil. This week he found cracks zig-zagged
for lOO to 200 feet, several inches wide at the top, and extending down
five to 20 feet to the water lone.
"They look like the results of earth tremors. The clayish soil has
contracted during the very dry summer and by some mysterious process the
long cracks just 'suddenly appear'. Why the cracks are so long and
clearly marked is not explained, except that they may be set off by a
minor earth tremor. Mere contraction of the dry soil should ordinarily
result in small scattered cracks and a settling."
