The difference between destructive and constructive margins is that destructive margins moves towards the continental crust causing it to go underneath it forcing the magma out if the volcano‚ yet the constructive margin tends to move away from a different plate which results in a volcano. Destructive margins also cause volcanoes this is a similarity that the destructive margins also has to the constructive

Spirit Lake‚ Washington – the water level rose by 80 metres after the eruption of Mount St. Helens in 1980. Huge quantities of debris-avalanche material caused the river to be altered in its depth‚ volume and surface area. Very violent eruptions of pyroclastic flows destroy life and property.

ERUPTION IN MONTSERRAT Bonnie Brooks Montserrat’s infamous volcano‚ Chances Peak‚ has been erupting continuously since the 18th July 1995‚ the first eruption in 350 years. The eruption was proved by scientists to be the equivalent volume of 100‚000 cars every day and in the first four months of this eruption the island suffered many jets of steam and small explosions. Consequently‚ the earthquakes were large enough to shake the ground after three years of earthquakes. Two years after the first

There were 142 recorded earthquakes over 2.4 in the 24 hours between March 26 and 27th. The volcano began to spew ash at 1236. (Girty‚ P. 2) The ash column reached 829 meters above the peak.

This leaves anybody outside vulnerable to the volcanoes attacks. This isn’t the only threat though. When pyroclastic materials escape the vents of Cinder-Cone volcanoes‚ some of these materials gather up into one huge wave that can be hot enough to make your blood boil. This wave tumbles down the side of the volcano‚ demolishing

The stages in the eruption of a volcano have tell-tale signs. After the earth tremors or earthquake the volcano might have a small eruption of materials. These will be deposited across a smaller area but leave distinct evidence. If there was a significant time gap between

Indo-Australian plate subducts under the Eurasian plate. In May until 27 August 1883‚ the eruptions took place until it blew the island apart. There is still part of the volcano‚ Rakata‚ which was the highest peak of Krakatoa. The eruption happened because of the super-hot steam that was created when the side of the volcano split and let ocean water come in to the magma chamber. The explosion was six times bigger than Hiroshima bomb attack in 1945‚ and the sound of the explosion was heard
