There are two types of rifting: Active rifting, which indeed implies the rise of a mantle plume under the lithosphere. This yields to the bulging of the lithosphere, then to its extension. In such ...

Not all large earthquakes produce huge rifts on land, but if you were unlucky enough to have one open up beneath you then the chances are you would fall into it. Another danger would be liquefaction.
