Action on Hawaii

Post by RAM »

Yo Brian: Kileaua made the national news this AM with that nifty little eruption last night-first of its kind I think thay said since the 1920s. Plenty of lava flows and fountains there but this was more explosive than typical I assume. Seems basaltic shield cones are typically mild eruptors whereas acidic-lava cones (adjacent to trenches-e.g. Mt. St. Helens, Krakatoa) are violently eruptive. Difference is basalt lavas are more fluid, lose their steam more quickly. Acidic (andesitic) lavas are viscous, hold steam and blow up like crazy if given the chance.

Best Tennesse could do last night was a big oil well fire started by a gas blanket in a low vallely ignited by a redneck who drove too close even after being warned not to. But it did make national news. Wonder if any Tennessee rednecks were on Hawaii last night? Hmmmm! Bad Bob

Geological stuff...and other stuff

Good morning down there Bob:

Certainly glad that you are safe. I am curious; could there be any connection between that low lying gas cloud and your recent bean fest?

Yo Bob,

Still picking the cinders out of my hair as we speak - nah, it was a tiny explosion as far as those things go. I was talking to a fellow who's family lived on the Big Island and remembers much more spectacular events as recent as the 50s and 60s. Not really violent explosions but 3,000 foot high lava fountains. Haven't had those in a little while. When you think that some of the newer lava flows have been within 300 years, it makes you think that it was really only a short time ago relative to geological activity in the islands. And those are from "dormant" volcanos (ie. the whole coast of Kona and a flow or two on Maui!)
