Famous Volcanoes
Thirty of the most famous volcanoes on Earth are Kilauea in Hawaii, Mt. St. Helens in Washington, Vesuvius in Italy, Fuji in Japan, Merapi in Indonesia, Pelee in the Caribbean,
Eruptions
These are the most deadly eruptions known. Other eruptions have been as big or bigger than these, but no one lived nearby to be threatened (for example the Valley of 10,000 Smokes eruption in Alaska in 1912). The Mt. St. Helens eruption in 1980 in Washington state was a far less dangerous eruption than these, only 61 humans died, although thousands of deer and other animals perished. The ancient eruption at Santorini Island in the Mediterranean Sea in about 1650 BC certainly killed thousands of people (and was the source of the Atlantis legend), but there are no real estimates of the number of deaths. Remember that all of the numbers of deaths listed here are best guesses; various books give different numbers. This list is based on data in Volcanic Hazards: A Sourcebook on the Effects of Eruptions by Russell J. Blong (Academic Press, 1984).

Deaths by Regions, 1600-1982
This bar graph shows the number of deaths in each volcanic region from 1600 to 1982. The total number of deaths was 238,867.

Volcanic Rocks
Igneous rocks begin as magma. Intrusive igneous rocks, like granite, form when magma cools inside the Earth. Extrusive igneous rocks, like the basalt lava flow in this photo, form at the Earth's surface. Volcanic rocks are extrusive igneous rocks. Photograph by Steve Mattox, July 1990.

All about Lava
Fluid Basalt lava flows Mauna Loa, Hawi'i. Viscous Dacite lava dome Unzen Volcano Japan. Fluid Basalt flows can extend tens of Kilometers from an erupting Vent. The leading edges of basalt flows can travel as fast as 10 kilometers on steep slopes but they typically
Lava is the molten rock that is poured out of the volcanoes or from crackes in the earth. It comes from the deep in the earth where the heat is great. There lava is called magma. When lava first comes to the surface it is Red-hot reaching temperatures from 7-12 times hotter than boiling water. What are lava flows? Well lava flows are streams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains.
Lava moves slowly, although the vapors are often toxic. Since the year 1600, less than 700 people have died from lava. That's an average of less than two a year, so you're pretty safe!
Volcanic Images
There is also video of volcanos.
Volcanoes outside of Earth
There have been volcanos on other planets, and their cones and craters can be spotted all over the solar system. The Voyager probes captured the first extra-planetary eruption on Jupiter's moon Io. there are all so lot of volcanos that will erupt
