An area of extensive basaltic lava flows occupies a graben, the NNE-SSW-trending Ch'uga-ryong rift, that cuts diagonally across the demilitarized zone between North and South Korea. One 40-km-long lava flow originated from the low Ap-san shield volcano, which has a 200-m-wide summit crate...
Earthquakes far from tectonic plate boundaries generally exploit ancient faults, but not all intraplate faults are equally active. The North American Great Plains exemplify such intraplate earthquake localization, with both natural and induced seismicity
are exposed at the surface. The shield was rifted apart betweenCanadaandGreenlandbyseafloor spreadingin theLabrador Seaand inBaffin Baybetween 90 and 40 million years ago. The rift subsequently moved to the east of Greenland, forming the Reykjanes Ridge that now separates the North American plate...

A sensible starting point is the Appalachian orogeny, which occurred roughly 300 Ma during the collision of the African and North American continents (Hatcher et al., 2010). Around 230–200 Ma, the supercontinent of Pangaea broke up, causing eastern North America to rift apart from Africa (...
