    My volcano is named Mount St. Helens, I bet you’ve heard of it. It is a very large volcano in Fashington (the state not the capital of the U.S.). It last erupted (out of the side of itself) on May 18th, 1980, and killed about 57 people, they think. The official death toll is disputed. It is located near the border of the Juan De Fuca and the North American Plates. Right where the oceanic crust started to melt, there was mt. st. helens right above it, it was probably formed by the two plates being in a different place and being a divergent plate Boundry, then later moving and re-shaping. explanation: link:

    The earthquake that I investigated was the 1960 Valdivia earthquake or great chilean earthquake. The great chilean earthquake on may 22, 1960 it occurred off the coast of southern chile near fault-line’s. “Faults are cracks in the earth caused by buckling and stress from the movement of the tectonic plates, movement along fault-lines tends to happen along plate boundaries”. The subduction of the Nazca plate under the South American continent is what caused the major earthquake. “The fault displacement source of the earthquake extended over an estimated 560-620 mile stretch”. The effects of the disaster left two million people homeless the death toll is approximately 1,600 people and more than 3,000 people were injured. Fun Fact: The Great Chilean earthquake is the most powerful earthquake ever recorded, at a magnitude of around 9.4-9.6.

    The Volcano I investigated is the Kilauea Volcano. The volcano is located is located on the southeastern side of the big island of Hawaii, which is also the island’s largest. The Volcano is active, and in fact, has been active for nearly 10,000 days, since 1983, spewing lava. “The east rift zone vent began erupting Jan. 3, 1983, and a summit vent has been erupting since March 19, 2008.” –
    The volcano however, is not formed by tectonic activity or plate movement. It is caused by a hot spot in the under the middle of the pacific plate.
    The Volcano is known as a “friendly volcano”, and has only caused a few fatalities. It is heavily analyzed by scientists, so they send out alerts for evacuations very accurately, though it damages structures that is in its path.

    The name of my volcano is Krakatau, it is a island volcano along the Indonesian arc, that lies at the convergent boundary between the Eurasian and Indo-Australia tectonic plates. When it erupted in 1883 it caused giant waves that were about 40 meters above sea level, destroying everything in its path, and killing about 36,000 people. Krakatau is still active, pretty much erupting all the time at low levels but every once or twice a year it has a big eruption, it has formed a small island named Anak Krakatau (meaning child of Krakatau).

    the name of my volcano is mount vesuvius. it is located in the gulf of naples in Campania Italy. mount vesuvius is the only active volcano in main land Europe. this volcano is part of the eurasian volcanic arc it lies where the african plate was subducted by the eurasian plate. this volcano has had a impact on humans because in 1944 this volcano unexpectedly erupted after an earthquake destroying the town and people next to it. it killed 10 to 20 thousand people be ether being buried in or in haling the toxic volcanic gas. here is a link for evidence to the last question.

    The volcano I investigated was Mount St. Helens,it is located on the southwestern side of Washington.The volcano is not currently active,but the last time it was active was July 10,2008,in total Mount St. Helens killed 72 people mostly because people breathed in the ash that came with the explosion and the rest of victims were around it when it did exploded(at most 25 people died from being near the volcano).The volcano’s explosion left bare and lifeless landscape and 250 homes were destroyed from the lava.The plate boundaries it is close to is the Juan de fuca plate and North America plate.

    Mount Rainer was formed in Washington 500,000 years ago, it last erupted in 1854. The volcano is considered to be active, even though it is considered active there is a heavy population surrounding the volcano. Because of that Mount Rainier is always being monitored by the USGS. T Mount Rainer is also located on the Juan de Fuca Plate on a divergent plate boundary. This is the website that I got all of my info from so if you want to see more stuff about Mount Rainier just click the link

    My volcano is Mt. Tambora located in Sumbawa, Indonesia. The volcano is still active to this day, but its last eruption was in 1967, its rating was 0 so it didn’t really have effect. The islands of Indonesia are on the Eurasian and Australian plate boundary, which is a convergent plate boundary. There is a subduction zone their so, the oceanic plate subducts under a landmass causing water to rush in, that causes the mantles melting temperature to go down, when the mantle melts, the magma rises upwards causing volcanos. In 1815 the volcano erupted killing 70,000+ people, the blasts rating was a 7 (super colossal), the explosion caused tsunamis 4-5m tall, and a the whole village of Tambora was wiped out, it lasted 5 days. The volcanos height went from 13,000ft to 9,000ft. That year was called “The Year without summer” because all the ash from the eruption, it went into the atmosphere causing temperatures to change worldwide, it got colder. People estimate that 100,000 more people died from crop failure, because of the eruption. here is a link to information:

    My Volcano is Behm Canal-Rudyerd Bay which is in Alaska-E it is a cinder cone and it is not currently active it was last active in 1990 is the last known eruption and it is Latitude is 55.32 and its Longitude is -131.05 and it hight is 500M it is currently is the convergent plates boundary make volcano because it pushes magma to the volcanos so they can erupt later on in life and it is by the Juan de Fuca plate this volcano affected a small human town and it burned down a small field near it and you can still see ashes and lapilli layers still there and this volcano is by these places in Alaska
    Saxman 21 mi (34 km) SW
    Ketchikan Gateway Borough 23 mi (37 km) NW

    The volcano I investigated is the Novarupta volcano. This volcano is located in Alaska. The volcano is not active, and the last eruption was in 1912. The boundary is the Alaskan-Aleutian plate boundary. The boundary caused the eruption and other earthquakes. How it caused it was from two plates converging on one another. How it impact the humans was destroying the buildings and having a lot of ash for 3 days.

    The volcano I was investigating was Mount Tombora its located in Indonesia . this mouton is a statovalcano the last eruption was in 1920. it was a moutian then magma seeped its way through and made it a volcano. when the eruption happen over 10,000 people died. in 1816 a year after the first sequence ion eruptions happened it was know as the season with out summer because crops and other vital materials wouldn’t grow which caused even more death in the area it infiltrated. 🗻

    The volcano that I investigated was Mt. Vesuvius. This particular volcano is located on the Gulf of Naples, Italy. It is one of several other volcanoes that belong to the Campanian volcanic arc. It is also the cause of hundreds of deaths in Pompeii when the dreaded volcano engulfed the city in a sea of fire and poisonous ash, trapping those lost during that fateful day. Mt. Vesuvius has erupted many different times, the most recent being in March, 1944.
