Coffee Conversation: Ice Quakes

Join us for the Pigeon Lake Watershed Association Online Coffee Conversation on Sunday August 23rd from 9:30 - 10:30 am with guest Don Davidson. #BYOCoffee

Cryoseisms or "ice quakes" are a phenomenon, caused by the sudden expansion of ice during certain climatic conditions, can result in spectacular ice ridges as well as considerable damage to property and shorelines. At Pigeon Lake, we frequently experience a large booming noise during the winter and can notice our cabins shaking when these ridges form. On January 1, 2018, a cryoseism
occurred which was measured over 2.0 on the Richter scale at several Alberta lakes during a period of rapid temperature increase. Find out why they occur and the effect they have on our shoreline.
