Since January I have as an intuitive been worried about a big quake in the vicinity of the Northern United States and southern Canada. I was most specifically worried about the Yellowstone Caldera. I thought that danger had passed and possible it has. However, something new appears to be going on in Southern Canada and the Northern 48 states and in Alaska.But it appears that 4.0s to 5.0s are going off from Alaska through Washington and now all the way over to near Toronto. People and pets were startled by it and felt it even in Buffalo, New York and in the Adirondacks area.
Also there was a 4.2 quake in Washington on June 17th
