Can powerful explosive volcanic eruptions result in climatic cooling for millions of years following an eruption?
yes
Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
What is large amounts of hot ashdustand toxic gases ejected from a powerful volcanic eruption?
An explosive eruption often does produce such a phenomenon called a pyroclastic flow.
Can geologist predict how powerful a volcanic eruption will be?
Yes
What are the stages of an eruption column?
An eruption column consists of hot volcanic ash emitted during an explosive volcanic eruption. An explosive eruption always begins with some form of blockage in the crater of a volcano When magma flows towards the surface pressure builds, eventually causing the blockage to be blasted out in an explosive eruption. The pressure from the magma and gases are released through the weakest point in the cone, usually the crater. The sudden release of pressure causes the gases in the magma to suddenly froth and create volcanic ash and pumice, which is then ejected through the volcanic vent to create the signature eruption column commonly associated with explosive eruptions.
