Mt. Tambora Indonesia

On April 5th, 1815, Mt. Tambora had it's first serious eruption which lasted a total of 2 hours.  Five days later, it erupted again and lasted 3 hours.   An eruption column collapsed and generated  pyroclastic flows that destroyed the villages of Tambora and Sanggar.  After 3-4 days, 50km3 cubed of magma formed into ash, making it the largest explosion in 1 000 years.  It continued until April 15th.  On the island Sumbawa, a rough total of 52 000 were killed plus the tsunami claimed many lives.  Look at Mt. Tambora on google maps.

Unzen Dake

Unzen is a chain of several strato volcanoes located in Japan. In 1792, Unzen erupted, one of the seven lava domes collapsed and caused a tsunami. Killing 15 000 people, the eruption is now recorded and thought of the worst volcanic related disaster in all of Japan. This volcanic chain has been active for a while and still is.

Mt. Laki

Mt. Laki erupted in 1783 in Iceland. The eruption lasted a total of eight months killing live stock and crops by acid in the grass which the animals would eat and contaminating the crops the citizens would eat. The only thing the citizens died from was lack of food and starvation. The eruption cooled the northern hemisphere 1 degree celsius. This was caused by 80 Mt of sulfuric acid being forced into the atmosphere.

Mt.Etna

Mt. Etna is a strato volcano and is the largest, active volcano in all of Europe.  Etna is located on the Sicily Islands of Italy.  It is rarely dormant and has been spewing ash for thousands and thousands of years.  In the year of 1669, Mt. Etna erupted.  The massive explosion lasted a week or two wiping out a total of    20 000 citizens.  Of course they could have survived if they fled, but not wanting to leave their beloved city, decide to stay and die.  To this day, Mt. Etna still erupts frequently.  If you go on google maps satellite, and type in Mt. Etna an interesting picture will appear.  

Mt.Vesuvius

Mt. Vesuvius erupted on April 24, 79 AD.  Vesuvius was a Caldera volcano, among the largest, most explosive volcanoes.   It is ranked as the 6th worst volcano erupted on Earth.  After eruption, the ash and magma reached the two Roman towns, Pompeii and Herculaneum.  Pompeii was buried one foot in ash.  The eruption lasted 19 hours at a temperature of 750 degrees Celsius.  The eruption of Mt. Vesuvius killed 10 000+.  They say that they found people with no heads because their heads and brains bursted because of the extreme heat.  Type in Mt. Vesuvius on google maps satellite and a cool picture will show.

Volcanoes

A volcano is an opening in the Earth's crust which pushes ash, molten rock or gas that is harmful to us and the environment. Volcanoes erupt in two ways. One way they erupt is when gas and thick magma build up and then give out and form a huge explosion. Another way they erupt is when there is less gas and the magma flows out. They are formed around plates or where they meet. The plates move in some way, shape or form. They are found a lot in a hot spot near the Southern islands of Asia, also known as the "Ring of Fire".
