Contrast this towards a kind of volcanic eruption described as a "big igneous district" (we will describe all of them right below as a LIP). These eruptions are actually marvelously big, creating over of 100km³ annually of lavas, as well as crucially, have actually overall eruption quantities over of 1 thousand km³ as well as deal with a location higher than 1 thousand km². (For contrast, the location of Southern Australia is actually approximately 1 thousand km²). These are actually continental-scale resurfacing occasions.
