Who decided that an apparently arbitrary difference of 1 second -- 44 versus 45 -- is significant? Do even the most dedicated of gazers _always_ watch their watch consistently enough to even say that it honestly was 44 versus 45 seconds, that such would be judged as "statistically significant" (which seems to be vital to some)?<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'>Indeed, after many years and _thousands_ of logged eruptions (and it truly is into the thousands by now), I have yet to hear of any significant meaning to T versus G, C versus Q and etc. Sometimes, if an eruption is closely watched, a series of afterbursts can be anticipated, BUT is there any meaning to afterbursts?<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'> <o:p></o:p></span></font></p> </div> <div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'>The only reasonably solid things I can recall as being at least minimally discussed recently, are: <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'>-- a bit of a relationship between total duration (regardless of the number of bursts) and following the following interval;<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'>-- a relationship between total Vent-Turban action after Grand and refill time.<o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt; font-family:Arial'>Will I follow up on these?
