Nevertheless, small to moderate eruptions can be devastating, the modest eruptions of Nevado del Ruiz (VEI 3) and Mont Pele (VEI 4) being good examples. Geological, historical and dating records for volcanic eruptions on land become less complete further back in time. Because dormant intervals between major eruptions at a single volcano may last hundreds to tens of thousands of years, dwarfing the relatively short observational record in many regions, it is misleading to restrict usage of "active volcano" to recorded human memories: we prefer to add another identifying word (e.g. Lava flows near Grants and Carrizozo are the youngest volcanic flows in the state (about 3000 .
