It still leaves unanswered the questions I posed early on that thread. I'll clarify here in case anyone can answer specifically:
Are there more active undersea volcanoes, or is our ability to detect them simply improving?
Is this merely the result of more funds flowing to geology, post-tsunami?
If there's more actual activity than there has been historically, where's the evidence that points to that conclusion?
I didn't find an emphatic, crystal clear proven answer to that question.
My IMPRESSION from reading a lot of sites about underseas volcanoes was that there's a lot more going on than anyone suspected. And, it appears that many have lighted off relatively recently. Certainly not paying attention to a phenomenon we didn't know existed would color the stats.
If you find a b etter answer to your question, please ping me.
None, really.
Actually, frankly, we'd have no way of knowing what unusual underwater volcano activity would be. Even now we likely could only detect less than 10% of underwater eruptions, as opposed to maybe less than 1% ten years ago.
I saw your question in the last thread and thought it was a good one there too. Do let me know the answer if anyone gets back to you on it. Thanks.
"Are there more active undersea volcanoes, or is our ability to detect them simply improving?"
None of them.
The story on the earthquake in Japan in another thread reports that in a year there have been 10,000 quakes, although I would surmise the vast majority of them of low magnitude.
The world is not coming to an end.
