Gas thought to have caused phenomenon in East Lake in Newberry Crater, related to the tremblors which have rocked the Northwest in the last few days, is problematical ... a slight seismic disturbance in the Paulian mountains might have opened a fissure, releasing imprisoned gases ... |

Penticton Herald, The, Penticton, B.C., June 30, 1925
"Tables moved, chair rocked here Saturday when slight tremors.
"Penticton visited by slight tremors of earthquake which devastated
Santa Barbara, California. Chandelier in store sways violently, and
pedestrians feel dizzy sensations. Lasted only a few seconds.
"Slight earthquake tremors were felt in Penticton at about 5:20 on
Saturday afternoon, which are believed to have been in connection with
the great earthquake in Santa Barbara, Califor-nia on Sunday which laid
waste to the city. The movement of the earth here is reported to have
been quite pronounced, lasting however only for a few seconds. Upon the
occasion of the great quake in San Francisco about 20 years ago, tremors
were felt quite perceptibly in Penticton district and particularly at
Peachland.
"No word has come from Victoria reporting detection of earthquake
tremors in British Columbia on Saturday, but many Penticton citizens are
confident that a slight earthquake was experienced here. Pedestrians on
Main Street at the time mentioned have reported a dizzy, whirling sensation
lasting for a brief period, and in one of the stores on the west side of
the street, the chandelier commenced to sway violently and even the
heavy counters moved slightly.
"At one residence on Winnipeg Street, the occupants were astounded
to see the chairs suddenly start to rock back and forth.
"Penticton has been visited by slight earthquake tremors at least
4 times in the last 20 years." |
