Earthquake In Ontario

There has been an earthquake in Ontario, north of Toronto. What is happening is that the tectonic collision that formed the mountains and ridges of the Appalachians is still going on. Remember the Humber Line that I discovered. It is the focal line of the curve in the Appalachians across Pennsylvania. Since the collision front was moving from west to east, it is just east of the Humber Line that earthquakes tend to occur.

This is the Humber Line. It starts at the "focal point" of the curve of the Appalachians, around Harrisburg in Pennsylvania, and extends northwestward to form the long axis of Georgian Bay. Image from Google Earth.

The Humber Line shapes the physical geography of the land, such as forming near straight-line shores. The far eastern shore of Lake Erie is part of the Humber Line and the earthquake in West Seneca, in February 2023, was, like the one in Ontario, centered just east of the Humber Line.

Here is a link to "Niagara Natural History Summary". This describes the natural history chronologically. The first part is about the geology of the Appalachian Collision, including the Humber Line. The second part is about much more recent glacial history, since the end of the last ice age.
