However, ancient smaller eruption events tend to be not recorded, compared with recent data. In the log frequency-VEI plot, incompletely normalized frequency which ignores the time-dependent nature of the database, provides a gentler regression line than when the data time-dependence is considered; that is, the former reflects low numbers of small eruptions insufficiently recorded.

This regularity may help our understanding about the potential of future large eruptions in not only individual volcanoes but also caldera regions.
