i know this is not a Volcano thread so you can just delete this post if you so desire.

The truth IS that in some circumstances they do coexist.

Volcanoes on Planet Earth are like icebergs, in so far as, 90% of them are underwater on the Ocean floors. For every Volcano that is erupting on land and therefore can't be hidden from the sheep, another 9 are erupting on the Oceans floors which are not reported.

These underwater Volcanoes are causing the Oceans to heat but as they only generally provide sea surface temperatures the heating is easy to hide.
