putting out an erupting volcano?

Is this possible?

If we had a helicopter big enough, picked up an iceberg and dropped it "down the hole" would that work

Like when you pour water in a hot frying pan :  you will get lots of steam.  Period.
In fact, most of the explosions associated with erupting volcanoes occur when the extremely hot magma reaches water layers or surface water.

If volcanoes can erupt under the ocean, I wouldn't hold much hope for putting them out with an iceberg.

Want data ?  Roughly, it takes about the same amount of energy to melt 1 kg of ice as to heat 1 kg of water from 0 to 80C; it takes about 6 times that much to evaporate it (at atmospheric pressure).  So your iceberg may lower the temperature of the magma - at least localy - by some 100C, and increase its viscosity.  But there will be hundreds of tons of hot magma (> 4000C) pusshing behind it.

As a firm believer of empirical study I took a box of matches and set alight the whole box at the explosive end...at the same time I dropped an ice cube on it....result ?...the explosive stuff still exploded !

Glad I could help and explain it so well !..
