How Accurate is the Movie?
Is Dante's Peak a real mountain?
Dante's Peak is a mountain in Death Valley, CA
It’s not a volcano, but it has a great view!
Does magma ever rise into hot springs?
Not really. It could happen, but I know of no actual events.
Are “tilt meters” real?
YES. They are used to measure changes in gradient.
Are robots such as “spider legs” really used in volcanoes?
NO. Although NASA tested one. Others are used for other purposes though.
Do volcanologists really wear gas masks around volcanoes?
YES. Otherwise, vulcanologists can die rapidly from colorless, odorless poison gases.
Paul describes events around “Mammoth Mt.” Is it a real place?
YES. Mammoth Mountain is a real supervolcano in Long Valley, CA. It really did become seismically active recently.
Can volcanologists feel the difference between magmatic and tectonic earthquakes?
Fire is usually the worst problem after an earthquake. Why?
Multiple fires break out, fuel leaks, and water mains break.
Is it normal procedure to drive into a stream current?
NO. It’s not only dangerous, but also very bad for the environment.
Does volcanic ash really choke aircraft engines?
Can lakes become severely acidic in a short period of time?
NO. Volcanic acidification typically takes years.
Is ash coarse- grained or fine- grained?
Very fine- grained. In the movie, they used shredded paper.
Are fast-flowing basaltic lavas typical for Cascade volcanoes?
NO. They have happened, but slow-flowing andesitic lavas are more typical.
Can you drive across an active lava flow?
SURE…go ahead! (just kidding). But you can drive on one after it’s cooled if it’s fairly level.
Is it possible to drive faster than a pyroclastic cloud?
NO. Depending on gradient, they can travel 600 m.p.h.
Can you think of some other things that were well done in the movie?
Can you think of some other things that were poorly done in the movie?
Have a nice day!
DANTE'S PEAK How Accurate is the Movie? Is Dante's Peak a real mountain?
13A.3 – Natural Hazards. Do Now What are four main earthquake hazards in California?
Outline Hazards Mt. St. Helens Case Study Precursors Pompeii Case Study.
Volcanoes can occur at Subducting boundaries Subducting boundaries Hot Spots Hot Spots Any type of climate Any type of climate.
Plate Tectonics. Crust The crust is formed from continental and oceanic crust The crust covers the whole Earth.

Volcano Vocabulary. Volcano A mountain formed when molten rock is pushed to Earth’s surface and builds up.
Volcanic Hazards p , web reading Volcano Facts Volcano Hazards Fall processes Flow processes Other types Predicting Volcanic Eruptions.
Volcano's Effects. Lava Flows These are streams of lava that come out of the volcano. Move slowly: People can get out of their way Trees/homes/buildings.
VOLCANOES. A few volcano basics… Active – a volcano that has erupted recently (geologically speaking) Dormant – (sleeping) has erupted within the past.
Unit 6: Earth Shaped from the Outside in Cycle 18: Volcanism & earthquakes Cycle 19: Plate Tectonics Cycle 20: Weathering & Erosion.
Volcanoes form as molten rock erupts A volcano is an opening in earth’s crust through which molten rock, rock fragments, and hot gases erupt. A volcano.
What causes volcanoes to erupt? Magma is hot, so it is less dense than surrounding rock and it rises to the surface Volcanic eruptions occur when.
Volcanoes * There are 2 (main) kinds of Volcanoes 1.Steep sloped with violent (explosive) eruptions 2.Gentle sloped with voluminous lava flows Mount Fuji,
VOLCANOES form where molten rock is vented at Earth’s surface. Where do volcanoes form in the context of plate tectonics? Volcanoes aren’t equally dangerous....
Chapter 10: Mountains and Volcanoes 10.1: Movement of rock builds mountains 10.2: Volcanoes form as molten rock erupts 10.3: Volcanoes affect Earth’s land,
Chapter 3: Volcanoes and the Rock Cycle Assignment 1: Volcanic Eruptions.
VOLCANOES. Volcano Basics Active – a volcano that has erupted recently (geologically speaking) Dormant – (sleeping) has erupted within the past few thousand.
Volcano Eruptions ~ What comes out of a volcano when it erupts?
Volcanoes “And the mountains shall be molten under Him, and the valleys shall be cleft, as wax before the fire, and as the waters that are poured down.
Volcanoes. l Evidence that we live in an active planet l The gods of the underworld l Millions of people live near active volcanoes –The greatest geological.
THIS IS With Host... Your Do not go in there! Volcanoes can burn Release some stress Do the wave! Volcanoes Affect Ah! It’s an.
How do volcanoes form and what affect do they have on the Earth?
There are many mountains in the world. Some mountains have fire inside:

What is a volcano? A weak spot in the crust where magma has come to the surface. EX:
VOLCANOES By: M.Wells. Facts About Volcanoes o Volcanoes are mountains that build higher and higher as they erupt. o Once a volcano erupts it might produce.

Volcanic Processes. Water Water can be heated by magma or lava. Process of heating water can create: –Geysers –Hot Springs –Fumaroles –Mud Pots Heated.
The main theory believes that there is an uneven distribution of heat in the mantle, caused by heat from the core. Hot mantle material will rise from near.
