In this PowerPoint I will be telling you about Volcanoes and what they do. There will also be a test at the end to see if you

can remember 5 facts at the end!

Mount VesuviusMount Vesuvius is the active volcano that looms over the Bayof Naples in southern Italy, has erupted well over 30 timesthat we know of. And yet its most famous eruption took

placeall the way back in A.D. 79, when a multiday eruption of lava and ash covered the cities of Pompeii in ash. Pliny the Younger, author of the only surviving eyewitness account, described a sudden explosion followed by blankets of ash that fell on people as they tried to escape. The total number of Vesuvius victims will most likely never be known, but archaeologists are aware of at least 1,000.

KrakatoaIn 1883, the volcano on the Indonesian island of

Krakatoa Erupted with 13,000 times the power of an atomic bomb.Hundreds in a nearby Sumatran town died almost

instantly when flaming ash destroyed their homes, and many

morewere washed away by mega tsunamis. Krakatoa itself

then slumped into the boiling depths of the ocean, but a newisland at the site was spotted in 1927, and it still

occasionally spits lava into the sky.

KrakatoaHere is a picture of Krakatoa! An estimated 36,000 people died and 42,000 people were made homeless.

Mount St. HelensMount St. Helens was getting ready to burst for nearly

two months before it exploded, not to mention the more

than 120 years it lay dormant. At 8:32 a.m. on May 18, 1980, a

5.1-magnitude earthquake triggered a sideways blast

swept the mountain’s north out some 15 miles at speeds of at

least faceaway into a cascading landslide that shot hot ash and

stone out some 15 miles at speeds of at least 300 m.p.h.

Mount TamboraTens of thousands of people were killed by

the apocalyptic eruption, subsequent tsunamis and ensuing starvation and disease. The largest volcanic eruption in recorded history changed the world's climate so much (even crops in Europe and North America failed)

that 1816 became known as "the year without a summer."

Mount TamboraHere is a picture of Mount Tambora! Tambora itself shrank several thousand feet and traded its peak for a massive crater at its summit.

Mauna LoaIt's fitting that the state created out of a

chain of volcanic islands would be home to theworld's largest volcano. Mauna Loa is located on the Big Island of Hawaii and in addition to being the largest, with a summit nearly

13,700 feet high, it is also one of the world's most active.

Mauna LoaHere is a picture of Mauna Loa! Since 1843, Mauna Loa has erupted 33 times, most recently in 1984.

EyjafjallajokullIt was like an overly contrived disaster flick: A mammoth cloud of ash from an Icelandic volcano creeps across the European continent, shutting down airports and stranding hundreds of thousands for days. Across the globe, people curse the volcano — or attempt to, since few can actually pronounce the name Eyjafjallajokull.

EyjafjallajokullAnd despite all our technological prowess, human ingenuity is shown to be futile in the face of an ash plume.

Mount PeléeMount Pelée, standing more than 4,500 feet high on the French Caribbean island of Martinique, erupted violently in May 1902, killing nearly 30,000 people — effectively the entire port city of St. Pierre. The catastrophe was so devastating that the term pelean —

to describe that particular kind of ash, gas and fiery cloud eruption — became part of

volcanic vernacular.

Mount PeléeHere is a picture of Mount Pelée! After the town was wiped out, Pelée went dormant for some months, until geologists discovered a lava dome, dubbed the tower of Pelée, that rose to more than 1,000 feet above the crater floor before eventually crumbling in March 1903.

Kilauea VolcanoKilauea is the youngest and most active Hawaiian shield volcano, located on thesouthern part of the Island of Hawai'i, knownas a Big Island. Hawai'i is the southern most and largest of the island chain, which owes its Existence to the very active Hawaiian hot spot.At present, Kilauea volcano is still having one of the most long-lived eruptions known on earth, which started in 1983 on the eastern rift zone.

Kilauea VolcanoHere is a picture of Kilauea Volcano! Its eruptions are prominent in Hawaiian Polynesian legends and written documentation about its activity go back to only 1820s when it started to attract interested visitor from all over the world and became one of volcanology's hot spots.
