Yes, many times, even within the last 450 years, there have been several such events.
It's widely believed that the eruption of a Super volcano, caused the entire Earth to Freeze, about 250 Million years ago, wiping out around 95% of all life on Earth. http://nz.news.Yahoo.com/a/-/world/5227472

How does volcanoes cause flash flooding?
Huge steam clouds are emited high into the sky and are cooled to create rain and if it's big enough it will caues flash flooding
What volcanic rock is cooled lava made up of?
Igneous rock is made up of volcanic rock that is cooled after flowing as lava. Much of this type of rock is made up of sulphur and iron. Crystals also form from this type of melting.
What was the lava from Mt St Helen's made out of when it erupted in 1980?
The material erupted in the 1980 eruption of Mount St Helens was of a composition known as dacite. Minerals common in dacite are primarily quartz, potassium feldspar, and albite. However most of the dacite from the 1980 eruption came out as ash and pumice, which are varieties of volcanic glass. Although the chemical components were there, the material cooled to quickly for the minerals to form.
What is an example of extrusive rock that has cooled too quickly for grains to form?
Obsidian, which is volcanic glass, is a good example.
Oceanic crust is composed of a volcanic rock that forms from quickly cooled lava called?
mainly basalt
Where in what country did the greatest volcanic eruption occur?
Hawaii, because hawaii itself is cooled lava
What warnings are there for people when there is a volcanic eruption?
cooled magma feel from the sky and almost killed a barberian and smoke was coming from the mountain

Cinders?
Cooled volcanic rock material
Where can tephra be found?
Tephra, the material ejected into the air during an explosive volcanic eruption, consists of molten lava materials such as pumice, cinders, and volcanic ash that have cooled and solidified as they fell through the air. Large tephra deposits form where the material lands and eventually become compacted into rock called volcanic tuff.
Is the town of Pompeii hot because of the lava?
No. First, Pompeii was buried by volcanic ash, not lava. Either way, the eruption that buried Pompeii was nearly 2,000 years ago. The ash cooled long ago.
What build up a volcanic mountain?
Cinder, cooled lava, and ash
How was Hawaii's archipelago developed?
Hawaii was made from cooled volcanic ashes
What are the two main properties of igneous rock?
There are lots, but they get sorted into 2 categories, volcanic and plutonic. Volcanic are rocks that cooled on/near the surface (quickly), and plutons are rocks that cooled deep below the surface (slowly).
What is volcanic ash?
Volcanic ash tends to contain a mixture of tiny, sharp pieces of rock and glass, made from liquid droplets volcano that have cooled quickly. It's abrasive and mildy acidic and is known as tephra. Volcanic ash is expelled with great force from a volcano during an eruption. When the ash falls, it is hot and deadly, and can ignite fires, and it can also be spread over a very wide area by winds.
How are volcanic rocks produced?
A volcano is formed when the molten magma (lava) beneath the crust is forced to the surface. Volcanic rock is lava that has cooled.
What volcanic rock is cooled lava made up of?
Igneous rock is made up of volcanic rock that is cooled after flowing as lava. Much of this type of rock is made up of sulphur and iron. Crystals also form from this type of melting.
