A long thread is growing longer at Leaside Chit Chat as members comment on the post of a resident near McRae and Airdrie Drives that the household is experiencing “large bangs that shake (the) house every once in a while. This has been happening for a few months and I think it is related to the construction, but am not sure. The bangs are loud enough to shake the foundation of the house and wake my dogs.” There have been a number of responses both serious and flippant (“Earthquake!”) but a couple of posts reference something called a “cryoseism.” They say “Leaside is overtop of a high water table. (The sound) is a frost/ice quake.
SEISMIC EVENT
An ice quake or a frost quake, is a seismic event that may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice. As water drains into the ground, it may eventually freeze and expand under colder temperatures, putting stress on its surroundings. ” Living is learning for those who have never heard of a cryoseism. They are also known as an ice quake or a frost quake. Wikipedia calls it a “seismic event that may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice. As water drains into the ground, it may eventually freeze and expand under colder temperatures, putting stress on its surroundings. This stress builds up until relieved explosively in the form of a cryoseism.”
