When does a volcano eruption begin?
A volcanic eruption starts with the build up of pressure in the magma chamber. A bulge in the crater may indicate a impending eruption. Earthquakes may also precede an eruption.
When was the loudest sound of a volcanic eruption heard and in which year?
The loudest sound of a volcanic eruption was heard during the 1883 eruption of Krakatoa in Indonesia. The sound was heard over 3,000 miles away and is considered one of the loudest sounds in recorded history.
What are tha things you do after and before during the volcanic eruption?
you are asking a seemingly simple question but it has a complex answer. Prior to an eruption you have the forming of the caldera. Then you have the eruption: here are some effusive eruption, central vent eruption,fissure eruption, subaqueous eruption, sub glacial eruption, pyroclastic eruption, ash-flow eruption. The most spectacular of all of them is the pyroclastic eruption. It throws off viscous gas-rich magmas and producesw a great deal of solid volcanic fragments. A volcanic eruption after is called clean up. The included link about Mt St Helens eruption will give you an idea on the potentially explosive power of a volcano.
What was the loudest volcanic eruption ever?
The loudest volcanic eruption in recorded history was the 1883 eruption of Krakatoa in Indonesia. The explosion was so powerful that it was heard up to 3,000 miles away and led to the destruction of the island.
What type of volcano is Aniakchak?
It is a volcanic caldera which is a large, bowl-shaped volcanic depression that forms when the top of a volcanic cone collapses into the space left after magma is ejected during a violent volcanic eruption.
What do you do after a volcanic eruption?
Clean up, usually. And rebuild or relocate.
What makes up a volcanic eruption?
Lava, cinder, arsh, gases, watervapour.
What happensin a volcanic eruption?
pressure builds up in the earth and pushes the magma up to the surface.
What causes volcanic reactions?
moving of tectonic plates and the build up of pressure within the volcanic mountain under the dried up lava which became rock after the previous volcanic eruption
What is the vei of eyjafjallajokull?
The VEI (Volcanic Explosivity Index) of the Eyjafjallajökull eruption in 2010 was 4, indicating a moderate explosive eruption with a volcanic plume rising up to 10-25 km into the atmosphere.

What Stages that lead up to volcanic eruption?
Fire,Ash,smoke clouds, and earthquakes

What happens to the number and intensity or small earthquakes just before an eruption?
Before a volcanic eruption, there is often an increase in the number and intensity of small earthquakes, a phenomenon known as volcanic seismicity. This occurs as magma rises towards the surface, causing pressure to build up and fractures to form in the surrounding rock. The increased seismic activity can serve as a warning sign of an impending eruption, indicating that the volcano is becoming more active. Monitoring these earthquakes helps volcanologists assess the likelihood and timing of an eruption.
