Some faults are active & others inactive. When movement occurs along an active fault, usually due to in-plate localized stresses, an in-plate earthquake will occur. Concerning in-plate volcanoes.
WebMay 21, 2013 · Well-documented inactive plate boundaries are shown by symbols in black. The tectonic development of oceanic crust is shown by episodes of seafloor spreading. These correlate with the rift and drift sequences at passive continental margins and episodes of tectonic activity at active plate margins.
