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.

How is the information on the volcanoes page organized?
The page presents four different kinds of threats that volcanoes pose and what to do before, during, and after an eruption.
What Three things that can occur during an eruption?
During a volcanic eruption, three key occurrences can take place: the expulsion of lava, which can flow down the sides of the volcano; the release of ash and volcanic gases, which can spread over large areas and affect air quality; and pyroclastic flows, which are fast-moving currents of hot gas and volcanic matter that can devastate anything in their path. These phenomena can significantly impact the surrounding environment and pose threats to nearby communities.
What is destroyed by a volcanon eruption?
A volcanic eruption can destroy a variety of things, including infrastructure such as buildings, roads, and bridges, depending on the eruption's intensity and location. It can also obliterate natural landscapes, forests, and ecosystems through lava flows, ash fall, and pyroclastic flows. Additionally, the eruption can lead to significant loss of life and displacement of communities in the surrounding areas.
Why is it possible for things to be preserved in a volcano eruption?
During a volcano eruption, certain objects or structures can be preserved due to rapid burial under volcanic ash, which can act as a protective layer against decay and natural elements. Additionally, the intense heat can sometimes create a condition known as vitrification, where organic materials are turned into glass, further aiding in preservation.
What is a pyro-clastic cloud?
A pyroclastic cloud is a dense, fast-moving mixture of hot gases, ash, and volcanic rocks that violently erupt from a volcano during an explosive eruption. These clouds can travel at high speeds down the sides of a volcano, destroying everything in their path and posing a serious threat to nearby communities.

The page presents four different kinds of threats that volcanoes pose and what to do before, during, and after an eruption.
What are the precautions for volcanic eruption?
A few things that can predict an occurance of a volcanic eruption can be seismic activity such as tremors or small earthquakes. The release of certain gases such as Sulfur Dioxide and other gases.
Can you list ten things that you would never see immediately after a volcanic eruption?
No. But if I had to I would pick things that were only native or existed in areas not near volcanoes. However, you did not say that you had to be next to this volcano immediately after a volcanic eruption. So no I cannot.
What is post volcanic phenomena?
Post-volcanic phenomena refer to the various activities and processes that occur after a volcanic eruption has taken place. These can include lahars (mudflows), ash deposition, landslides, gas emissions, and the formation of new landforms such as lava domes or calderas. Monitoring and studying these phenomena are crucial for understanding the long-term impact of volcanic activity on the environment and local communities.

How do you get tsunamis?
You get tsunamis from one in three things volcanic eruption Earthquake Land slides, The most common is a earthquake
List the troubles affecting Mycenaean Greece before its collapse?
Some historians believe that a tidal wave triggered by a powerful volcanic eruption on the island of Thera was responsibile for the devastation.<--- This is incorrect the volcanic eruption may have led to the disappearance of Minoans not the Mycenaeans. Things that may have led to their destruction are: the fact that they were fighting one anuther, the major earthquakes that cause lots of damage, and the invaders that invaded them in the twelfth century B.C.
What are resources to get through a volcanic eruption?
some things are turning off gas water and electrity and avoid any amount of gas:)
How is the information in the During section of the Volcanoes page organized?
The information in the "During" section of the Volcanoes page is organized chronologically, typically describing the events, activities, and phenomena that occur while a volcano is erupting or showing signs of potential eruption. It may include details about seismic activity, gas emissions, magma movement, and the eruption itself.
What do you do after a volcano?
that depends on the volcano. a lot of different things can happen in a volcanic eruption. generally though, get out of it's way. there's nothing you can do to stop it from happening...
What are 2 things that might happen to warn us that a volcanic eruption could occur?
maybe the smoke and the lava. that might be a clue. even animals can be a sign of an eruption, animals leave the area and seek refuge in a safer area.
