The only effective method of risk mitigation is evacuation prior to such eruption from areas likely to be affected by pyroclastic flows. 5 - Lahars ( volcanic mud and debris flows) are a common major volcanic hazard for people and property. Laharslikewise proceed very quicky and possess great destructive power.

What are some Difficulties after an eruption?
Volcanic clouds of dust, hot larva flows
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.
How can a volcanic eruption affect the sun?
A volcanic eruption here on Earth can not affect the Sun. However, a volcanic eruption here on Earth can put particles of ash and some volcanic gases into the atmosphere that affects the transparency of Earth's atmosphere to sunlight. With the ash content the skies near the volcano go dark during the day and with the gases (especially sulfur oxides) the amount of cloud cover increases causing sunlight to be reflected and the air to cool.
What are the stages of an eruption column?
An eruption column consists of hot volcanic ash emitted during an explosive volcanic eruption. An explosive eruption always begins with some form of blockage in the crater of a volcano When magma flows towards the surface pressure builds, eventually causing the blockage to be blasted out in an explosive eruption. The pressure from the magma and gases are released through the weakest point in the cone, usually the crater. The sudden release of pressure causes the gases in the magma to suddenly froth and create volcanic ash and pumice, which is then ejected through the volcanic vent to create the signature eruption column commonly associated with explosive eruptions.
How Volcanic eruption cause the destruction of forest?
By burning everything in its path and after thats done the ash can also do some damage.
Why are lava flows usually of less immediate danger to humans beings than some other volcanic hazards?
Volcanos erupt
What are some of Chile's natural hazards?
hurricanes such as earthquakes, tidal waves, tsunamis, tornado's, and whirlpools.
Was Krakatoa volcanic eruption a plinian eruption?
Yes, though some would call it ultra plinian.
What are some example constructive force?
Volcanic Eruption. It builds land.

A volcanic eruption can be frightening and destructive, but it can also help humankind. Choose two positive outcomes of a volcanic eruption?
two benefits of a volcanic eruption one is that it help plants grow and Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth
Is it true or false that some types of volcanic activity do not involve the eruption of lava?
this statement is true
What are some volcanic gases?
The most common volcanic gas released in an eruption is water vapor. Water vapor is followed by carbon dioxide and sulfur gas.
