Our -Indians were much disturbed except Cosotasket and Tatlehasket and a few others, hard old nuts. They thought the "Father" was angry and sent for the priests, and many were baptized."

Houses were shaken, crockery rattled, and a heavy rumbling noise heard. The effects seem to have been local as we have not heard that it has been noticed in other parts of the province." _______________________________________________ Chilliwack Progress, The, Chilliwack, B.C., April 4, 1900 "It is reported on good authority that two distinct earthquake shocks were felt on Friday evening about ten o'clock. By a strange coincidence the Premier was at that instant in the midst of his speech at Henderson's hall. " _______________________________________________ Chilliwack Progress, April 5, 1950 "Fifty years ago "April 4, 1900 "Two distinct earthquake shocks felt in district." Vernon News, The, Vernon, B.C., February 20, 1902 "A slight earthquake shock was felt at Grand Forks last week." _______________________________________________ Chilliwack Progress, The, Chilliwack, B.C., August 26, 1915 "HOPE NEWS "Earth tremors, two distinct shocks, were felt in Hope on Wednesday morning." _______________________________________________ Penticton Herald, Penticton, B.C., December 10, 1936 "OLIVER FEELS EARTHQUAKE "Distinct Tremors Felt in South on Three Occasions. "A tremor which rocked the foundations of buildings throughout the whole of the south end of the Okanagan was felt on Wednesday evening December 2 when to the best of everyone's belief, an earthquake disturbed the peace and serenity of the district. The shock was felt in Oliver about 9:30 o'clock, causing pictures to shake on the walls and vases to totter. The earthquake lasted only a few seconds and was followed by a slight tremor about three minutes later. At various times throughout the night, slight tremors were felt but no serious damage has been reported. Another tremor was felt at about 3:30 o'clock the following morning but had not the velocity of the first shock." _______________________________________________ Penticton Herald, Penticton, B.C., July 4, 1940 "PIONEER DAYS "15 years ago in Penticton. "Slight earthquake tremors were felt in Penticton at about twenty minutes past five o'clock on Saturday afternoon, June 26, which were beLieved to be connected with the quake that wrecked much of the town of Santa Barbara, Cal. The earth movement was even more distinct, although it lasted for only a few seconds." Weston Geophysical Research, Inc. Note: This event may in fact be June 28, 1925, a Montana earthquake. _______________________________________________ Vernon News, The, Vernon, B.C., February 17, 1949 "DISHES RATTLE, PICTURES SWAY AS IQUAKE FELT "Kelowna - Goods were shaken from stove shelves and household furniture shifted when a sharp earthquake rumbled across the Okanagan Valley a few minutes after 8 o'clock Saturday night of last week. "The tremor was feat in Peachland, Kelowna, Westbank, Okanagan Mission and as far south as Naramata. The quake, however, appeared sharpest in the Summerland district. "Worshippers at the Summerland Baptist Church rushed from the structure believing the building had been struck by a heavy truck as walls shook and windows rattled. No serious damage was done and no one was injured." Weston Geophysical Research, Inc. Note: This account may document February 4, 1949 event. _______________________________________________ Penticton Herald, Penticton, B.C., September 29, 1927 "QUAKE SHOCK FELT HERE EARLY MONDAY "A slight but perceptible, earthquake shock was felt in Penticton early on Monday shortly after 7 o'clock. Of brief duration, it was probably more pronounced on the beaches than in the town. In some homes, chairs were rocked and in others the tremor was barely felt, as Mother Earth adjusted her strata covering in this neighborhood. "About a year ago, a similar shock was felt in Penticton but much more so at Narcgnata, at the time when tremors were experienced farther down the coast and among islands in the Pacific. In the present instance, there are no reports of earthquakes at other points. "It is about 14 years since earthquake shocks have been felt here, other than the 2 chronicled above." _______________________________________________ Pentiction Herald, Penticton, B.C, September 29, 1927 "Naramata. A elight earth tremor was felt here on Monday morning a little after 7 o'clock, but seemed to travel in a limited area, being noticed only in certain locations." _______________________________________________ Penticton Herald, The, Penticton, B.C., March 1, 1928 "Earth Tremor was noticed on Tuesday (28 Feb.). "Several residents of Penticton, particularily in the Skaha Lake section, reported a slight earth tremor about 5 o'clock on Tuesday morning. "Mr. McDowell states that the 'quake' was like a heavy truck rumbling over a bridge." _______________________________________________ Penticton Herald, Penticton, B.C., August 21, 1930 "A mysterious explosion in the neighborhood of Norton Street shook nearby houses, rattled window panes and dishes on the shelves at approximately 9:30 o'clock, Monday evening. The explosion took place between Norton Street and the day banks to the east. it has not been found as yet what caused the disturbances. No damage was caused by the accident." _______________________________________________ Penticton Herald, The, Penticton, B.C., May 3, 1934 "ROCK CREEK "on Wednesday at 4 a.m. there was a low, rumbling sound which lasted several seconds. Some of the people thought it might have been from an earthquake somewhere." etc. (RSL - additional information about quakes after 1928)
