is a stratovolcano and is located on Sumbawa Island, Indonesia and is still currently an active volcano. The volcano was 14,000 feet high and was the tallest peak in Indonesia until its eruption in 1815 which caused the volcano mountain to decrease to 9,354 feet. The volcano is sitting on a subduction zone and is surrounded by an oceanic crust. There has been several eruptions from this particular volcano but the most destructive and memorable eruption was on April 5th in 1815 which took the lives

Montserrat is a small island in the Caribbean. There is a volcanic area located in the south of the island, called Soufriere Hills. The volcanic peak in this area is called Chances Peak, which had been dormant for over 300 years. Then in 1995, the volcano began to give off warning signs of an eruption (small earthquakes and eruptions of dust and ash). Once Chances Peak had woken up it then remained active for a period of 5 years. The most intense eruptions occurred in 1997. Montserrat is a small

Seismologists were able to take a deeper look into the volcano and found that there is a significantly large magma reservoir beneath the magma chamber. This newly found body of magma(reservoir) is more than four times the size than the body of magma that lies above it. This new information and its finding outs Yellowstone at the top of the list for the "largest volcanic site on Earth". However, doesn't mean that it is the most dangerous volcano out there. Yellowstone hasn't had a catastrophic eruption

mantle is being sucked into the space created by the tilting plate. At 3350m tall and covering an area of 1250 km^2. Mount Etna dominates the landscape of northeastern Sicily, Italy. Mount Etna has the longest documented record of eruptions of any volcano in the world. Similarly, the island of Montserrat lies on an island arc on a destructive plate boundary between the caribbean plate and North

lava). • They’re typically located at destructive boundaries. • The eruptions from these volcanoes tend to be a pyroclastic flow (a mixture of hot steam, ash, rock & dust.) rather than a lava flow. • A pyroclastic flow can roll down the sides of a volcano at extremely high speeds & with temperatures higher than 400°C. Volcanic eruptions can have overwhelming effects on the environment & people Although, unlike earthquakes, volcanoes can also have a positive impact on an area. Positive + & negative

Some hazards of an eruption of Mount Saint Helens are a pyroclastic flow which is a hazardness fast-moving current of hot gas and rock (collectively known as tephra). It can reach speeds moving away from a volcano of up to 450 mph and reach temperatures of about 1,830 °F. Volcanic ash is another hazard and is up made of tiny fragments of jagged rock, minerals, and volcanic glass. Volcanic ash is hard, abrasive, and does not dissolve in water. Generally, particles of volcanic ash are 2 millimeter

The cities were in the rebuilding process when the most devastating volcano occurred. On August 24, 79 A.D., the volcano erupted and destroyed Pompeii and Herculaneum. Some of the 20,000 people fled the city while 2,000 of its society were unable to successfully escape the volcanic ash and rocks (History). With the excavations of Pompeii you

This catastrophic explosion was preceded by many smaller, warning eruptions, and on March 27, highly pressurized steam created a large crater through the volcano’s ice cap. Throughout the next two months, over 10,000 earthquakes had struck the volcano, and the crater was left with a radius of over 200 m. On the morning of May 18, a powerful earthquake caused the entire northern face of the mountain the break off and slide downward in what became known as one of the worst landslides ever, (Brantley

Arianya Sather-Gonzalez Period:6 Mount Vesuvius’ eruption caused mass destruction and many deaths. It was a drastic event that has been recorded in the hearts of many. This great tragedy occurred on the 24th of August, 79 AD. Mount Vesuvius, a volcano in Italy, erupted in a rather unexpected way. Mount Vesuvius sprayed poisonous volcanic gases, and sent clouds of ash into the air. If you weren’t crushed and suffocated by ash, you choked to death on the poisonous gases. Historians have learned
