During a volcanic eruption, molten rock, ash, and gas are expelled from the volcano's vent. This can create explosive eruptions that send ash clouds high into the atmosphere, affecting air travel and air quality. Lava flows can destroy everything in their path, while ashfall can cover landscapes and impact local ecosystems. Additionally, volcanic gases can pose health risks to nearby populations.
What else can I help you with?
Is an ash fall a volcano?
No, an ash fall is not a volcano. An ash fall occurs when volcanic ash and debris are ejected from a volcano during an eruption and then carried by winds to surrounding areas, causing the ash to fall to the ground.
What does eruption cycle mean?
An eruption cycle refers to the sequence of events that occur during a volcanic eruption, which typically includes phases such as pre-eruption activity, the eruption itself, and post-eruption processes. This cycle can vary in duration and intensity, depending on the volcano and geological conditions. It often encompasses changes in volcanic activity, gas emissions, and ground deformation, providing insights into the volcano's behavior and potential future eruptions. Understanding these cycles helps in assessing risks and improving eruption forecasting.
A form at the top of a volcano after eruption has stack?
After a volcanic eruption, the formation at the top of the volcano is typically referred to as a caldera. This occurs when the magma chamber below the volcano empties during an eruption, causing the ground above to collapse. The resulting depression can be filled with water, forming a lake, or may remain as a large, open crater. Over time, new volcanic activity can lead to the growth of new cones or domes within the caldera.
Is this correct pyroclastic flows from composite cone volcanoes are known as calderas?
No. They are simply called pyroclastic flows. A caldera is a depression formed in the ground when a volcano, usually a composite volcano, collapses as the magma chamber partially empties during an especially violent eruption.
What are the weather types before a volcano?
Since a volcanic eruption is a geologic event rather than a weather event, there will be no indication from the weather prior to an eruption. There are, however, geologic indicators that can point to a future eruption. Indicators include earthquakes near the volcano, venting of hot gas, and deformation of the ground.
If you come close to a volcano can you die?
If it an active volcano, yes you can. Lava can be several thousand degrees, and poisonous gasses are given off during an eruption. Sections of ground are unstable and can collapse. During an eruption, it is a VERY unsafe place to be.
What magma is called after it erupts above ground?
Magma is called lava once it erupts above ground. Lava is molten rock that flows from a volcano during an eruption.
Are craters volcanic bombs?
No. A crater is a circular depression in the ground formed by an impact or explosion. A volcano bomb is a blob of lava hurled out during a volcanic eruption.
Is an ash fall a volcano?
No, an ash fall is not a volcano. An ash fall occurs when volcanic ash and debris are ejected from a volcano during an eruption and then carried by winds to surrounding areas, causing the ash to fall to the ground.

Do the movements in the ground cause the ground to shake?
yes also the faults rub together and make it shake into an earthquake and the eruption of a volcano can start a earthquake.
Was montserrat eruption predicted?
Yes, the eruption of the Soufriere Hills volcano in Montserrat in 1995 was preceded by signs of increased volcanic activity, including earthquakes, gas emissions, and ground deformation. Scientists had been monitoring the volcano and had issued warnings about the potential for an eruption.
What hap pends during volcanic eruption?
during a volcanic eruption the plates shift causing the ground to tremble (kinda like an earthquake) causing the tightly packed magma to escape through the top of the volcano. when the magma reaches the top its called lava (but any idiot should already know that:))

What happens to the ground after the volcano has erupted?
nothing just it stays the same
