Unlike much of the rest of Japan, the Kitami Mountains are not very seismically active.

[1] The highest point in the Kitami Mountains is Mount Teshio.

Mount Teshio sits atop the Wenshiri horst.

[2] Rocks from the Kitami mountains are mostly sedimentary from the Cretaceous-Paleogene periods.

Volcanic rock was placed down on top of this from volcanoes that erupted in the Miocene or later.
