Volcanoes are very unpredictable, they might never know. All they can do is watch how much the eruption declines and assume it will continue to do so.
The reason scientists can't tell when it will stop erupting is because they can't tell how much molten lava is under the volcano. Even if the volcano doesn't stop erupting, flights within Europe may be resumed, the reason we're getting all this ash is because the molten lava hits the iceberg on top of the volcano and the sudden change in temperature and pressure gives off masses of fine ash.
The most dangerous volcano is a volcano that is erupting violently, spitting out lots of lava, rock and ash.The effect of a volcano can disrupt countries across the world, as I am sure you know from the eruption in Iceland.
`when was the first volcano seen if you know please tell me because i really do not know when they where first seen.
Iceland Oh by the way, if you want to know more about the volcanoes, go to youtube and type "The volcano song" it is really hilarious...
because they want to know more facts
well we dont know
Mount Krakatua is active, due to what scientists know.
Volcanoes have been erupting on the Earth a very Long time so no one on Earth at this very moment will not know.
Approximately 300,000,000 people were affected by the Iceland volcano but i dont know a complete answer because i didnt count all the people like a world person counter? Beefinator and Cleggnut x
Geothermal energy
look i dont know well i was searching but i couldnt even find the longest volcanoes name
Scientists explore volcanoes in order to study its past eruption and/or when it will possibly erupt again. If the volcano is inactive they examine the old rocks around it in order to know the history of that volcano. There are both active and inactive volcanoes both of which are studied by scientists.
