A story today (http://news.yahoo.com/s/nm/20060809/..._volcano_dc_11) claims that Filipinos and "scientists" are worried that a full moon may spark a volcanic eruption. They claim it's due to increased gravitation pull of a full moon...

Is this Bad Astronomy?

I have heard the theory that a moon that passes directly overhead of a volcano (or anywhere for that matter) has a slightly more gravitational pull than when it passes farther away. But what about a full moon, other than a brighter night sky would cause any changes here on Earth?

Some of the supporting quotes in the article cite such rock hard theoretical evidence as "My parents told me that a full moon triggers an eruption...", and that full moons coincided with THREE of the last FIFTY eruptions. Now I'm no statistician, but if full moons happen once every roughly 29 days, isn't two coincidences EXPECTED, and three not that remote a possibility?

Maybe I'm becoming too skeptical....
