Either there has been a change in dynamics, or the geological record becomes spottier the farther back we go, as larger, younger events destroy the evidence of older events.mickeymanhttps://www.blogger.com/profile/05294892836443576042noreply@blogger.comtag:blogger.com,1999:blog-831580070245692063.post-33911177036176756452011-11-28T10:30:04.598-05:002011-11-28T10:30:04.598-05:00I've heard the 700k-year average statistic for...I've heard the 700k-year average statistic for the CO caldera before, but I've never heard a dispersion statistic, confidence interval, or the like.<br />Do we think that is because we have too few observations to make this type of datum meaningful?nycerrollhttps://www.blogger.com/profile/05569834993782980683noreply@blogger.com
