Why might a volcanic eruption lead to cooler temperatures over a large area around a volcano?

Volcanic eruptions can releases significant quantities of ash into the atmosphere. This ash acts to reduce the reduce the solar radiation reaching earth's surface and so can cause a reduction in average temperatures.

∙ 12y agoWhen a volcano erupts it throws out large volumes of sulfur dioxide (SO2), water vapor, dust, and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols are produced by volcanoes. Because they reflect solar energy back into space they have a cooling effect on the world. The greenhouse gas, carbon dioxide is also produced however the CO2 produced is insignificant when compared to emissions created by humans!

∙ 12y agoThe eruption throws up clouds of dust and other small particles. These can block or reflect the radiation from the sun causing the earth to cool for several days, sometimes weeks. This reflecting effect is called albedo. The same albedo effect is seen with the ice caps and glaciers, which reflect a lot of the sun's heat.

How do people respond to a volcanic eruption?
Mainly by re-building the island and making sure the volcano is safe to be around.
How effect a volcano eruption to people?
Volcanic eruptions usually displace survivors as the area around the volcano is usually rendered uninhabitable. The amount of volcanic ash emitted from the eruption also changes the air quality which can also be dangerous.
Is Krakatoa a oceanic volcano?
Well after the eruption 1883 eruption Krakatoa was an Oceanic volcano, (around 1889) until it grew and regained it's height. It is now a land volcano.
Why might a major volcanic eruption lead to cooler temperature over a lrge area around the volcano?
when a large volcanic eruption happens, it'll most likeyl send up a large gas cloud into the air that blocks out the sun for a while. the blockage of the suns heat cools down the surrounding area until the cloud dissipates
How either an earthquake or volcanic eruption occurs?
Earthquakes occur when two plates of the Earth's crust collide. The collision creates a seismic wave, shaking the earth for miles around the collision. Volcanic eruptions occur when the pressure becomes too great inside the volcano, forcing the magma up through the vents and the main opening in the volcano.
Why might a major volcano eruption lead to cooler temperatures over a large area around the area?
Because when the volcano erupts it lets all the hot volcanic acid and lava out of the ground making the earth's surface cooler.

Why might a major volcanic eruption lead to cooler temperature over a large area around the volcano?
Blocking of solar radiation from ash in the atmosphere causing less radiation to reach surface cooler temperatures. *I <3 cupcakes!*:)
By What process can the volcanic eruption affect temperatures around the world?
The sulfur cloud that comes out after a volcanic eruption covers the earth's atmosphere, stops much sunlight from reaching Earth, and makes the Earth colder by 2 to 3 degrees Celsius.

Where is volcanic ash found?
Volcanic ash can be found above the crater, around the volcano and even miles and miles away from the volcano, depending on the size of eruption. It will rise up into the sky and then either remain in the sky (for very fine ash particles) and be carried by high-altitude winds around for a certain period of time or fall to the ground almost immediately after the eruption.
Are there signs for the eruption of volcanoes?
Before a volcano erupts, there is normally an increase in earthquakes, you might see some volcanic ash come out, you might see an increase in gas or steam around the volcano, and you might see a change in height or shape of the land around the volcano.
Is a volcanic eruption described as severe or serious?
It depends on the size and generally everything about the volcano. If it is a big volcano with a big eruption, then it would be severe. If it was a dormant volcano with a big eruption then it would also be severe, but if the volcano doesn't harm the general populace then it won't be dangerous at all. Most volcano eruptions would probably be severe though because of the general populace living around it (Hawaii) or because the volcano was dormant for so long, that it was unexpected.(Mt.Helen)

What are the effects and cause of a supervolcanol?
A super volcano is a huge sized volcano that can erupt, the eruption will create crater sized holes around the eruption.
