Thanks Arnold, Horatio - was hoping we would get something positive out of the exchange.

On another tack,
Kavachi Submarine Volcano towards the end of its 6 week (average) eruption cycle. About every two years it would build itself up from one of the vents from the seamount (different vent most times), to a height of about 30 feet above the surface, and throw molten stuff and steam up to about 500 feet. Also when the ocean swells came rolling through there would be a lot of steam. Quite spectacular to see. Then as it started to die down, the eruptions would become less frequent after a month, and in another month it would be collapsed back below the surface as a muddy stain again.
Further east, Tinakula was smoking all the time, and would squeeze rocks the size of Volkswagens out and roll them down 2,000 feet into the ocean
