volcano that put the world in an ice ago a couple hundred years ago?

Answer 1

There was also Mt. Tambora in the Indonesia area which erupted in April 1815. The ash and debris that was ejected into the atmosphere clouded out the sun for a few years. Temperatures worldwide varied dramatically such that the year 1816 came to be referred to "The Year without a Summer".

Answer 2

There was no ice age a couple hundred years ago.

In the year following the eruption, average global temperatures fell by as much as 1.2 degrees Celsius. Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888[citation needed]. The eruption injected an unusually large amount of sulfur dioxide (SO2) gas high into the stratosphere that was subsequently transported by high-level winds all over the planet. This led to a global increase in sulfuric acid (H2SO4) concentration in high-level cirrus cloud. The resulting increase in cloud reflectivity (or albedo) would reflect more incoming light from the sun than usual, and cool the entire planet until the suspended sulfur fell to the ground as acid precipitation

Krakatoa (Indonesian name: Krakatau, Portuguese name: Krakatao) is a volcanic island in the Sunda Strait between Java and Sumatra in Indonesia. The name is used for the island group, the main island (also called Rakata), and the volcano as a whole. It has erupted repeatedly, massively and with disastrous consequences throughout recorded history. The best known eruption culminated in a series of massive explosions on August 26-27, 1883.

The 1883 eruption ejected more than 25 cubic kilometres of rock, ash, and pumice [1], and generated the loudest sound ever historically reported — the cataclysmic explosion was distinctly heard as far away as Perth in Australia (approx. 1930 miles or 3100 km), and the island of Rodrigues near Mauritius (approx. 3000 miles or 4800 km). Atmospheric shock waves reverberated around the world seven times and were detectable for five days[2]. Near Krakatoa, according to official records, 165 villages and towns were destroyed and 132 seriously damaged, at least 36,417 (official toll) people died, and many thousands were injured by the eruption, mostly in the tsunamis which followed the explosion.

The eruption destroyed two-thirds of the island of Krakatoa. Eruptions at the volcano since 1927 have built a new island in the same location, called Anak Krakatau (child of Krakatoa).[1]

Answer 3

There was one in Iceland in June 1783 - Laki - which erupted for about 6 months. Due o the slightly odd weather situation at the time the ash was blown across Europe from Berlin via Prague and Paris to Great Britain. The sun was blocked out for about six months, crops failed and many people died because of the poisonous fumes.

Answer 4

Krakatoa is probably the big one you are looking for, but there were also others in Central USA, in Washington State area and in Russia around the same time too.
