If the magma is more viscous, the eruption is stronger.
If the magma is more viscous, the eruption is stronger.
Cotopaxi volcano is in Ecuador. A volcano magma can be measured during and after volcano eruption. The Cotopaxi eruption in 1987, its lahar has travelled for 60 miles.
The amount of pressure that pushes up the magma in a volcano
Volcanic ash forms when rock or liquid magma is reduced to tiny fragments by an explosive eruption.
magma flows up to form the eruption
The area where magma collects inside a volcano before an eruption is called the magma chamber. This is a reservoir beneath the volcano where molten rock accumulates and builds up pressure, eventually leading to an eruption.
magma and heat pressure
If a volcano's magma is high in silica, the volcano will probably erupt explosively. If the magma is not high in silica, the volcano will probably erupt quietly.
The cause of St Helens Volcano Eruption in the year 1980 was a 5.1 magnitude earthquake. The volcano didnt erupt for 120 years before this eruption .. so all the magma in the magma chamber had alt of pressure and was pushed out. the volcano was in a position where plates move.
the magma moving up will cause a eruption
magma appears after a volcanic eruption.
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
