[Geysers] Ol Doinyo Lengai

[TSBryan at aol.com]

Here's something out of "New Scientist" magazine (17 December 2005, page  52) 
that might sound a bit familiar, again showing a relationship in volcanic  
versus geyser action.
 
Researchers studying the nearly-constant efusion of the highly fluid,  
carbonatite magma at ol Doinyo Lengai (Tanzania) note that the "activity  increased 
when atmospheric pressure was falling or at a minimum. The researchers  
suggest that falling pressure might trigger an eruption by causing a slight  
expansion of the gases in the lava. They also noted more eruptions when the Moon  was 
closest to the Earth, possibly because of the stronger tidal pull." They do  
go on to note that "they need a lot more data to support these theories."
