Such series did also take place now and then in the early 1990s but, so far as I know, the only know such episode since then (until now, of course) was in 2005, per electronic data reported by Ralph Taylor. The height of those subsequent eruptions could easily exceed 50 feet, rising as they did from a mostly-empty crater.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV> <DIV> </DIV> <DIV> <DIV>In a message dated 6/6/2011 7:03:54 P.M.
