Heavy ashfall can

make it impossible

to breathe.

The powdery ash that

volcanoes eject can float

around the world.

Mount St. Helens, in Washington State,

U.S.A., caused the largest landslide

known on Earth when it erupted.

Magma flows to Earth’s

surface because it is lighter

than the solid rock around it.

Lava can reach 2,000 degrees

Fahrenheit—four times hotter

than your kitchen oven!

An umbrella won’t help! Lava blown

from a volcano hardens into solid rock

in the air, and the pieces fall like rain.

In the United States alone, 80 volcanoes have

erupted once or more in the past 500 years.

The heat from lava causes the

plants it buries to release

gases and explode.

Volcanoes can change the weather.

Mount St. Helens

destroyed eight bridges

when it erupted.

When lava reaches the

ocean, it cools rapidly.

It breaks down to form

black sand beaches.

A volcanic eruption can

blow apart a mountain.

Lava that cools into rough

pieces is called aa (AH-ah).

Ash in the sky can make day

as dark as night.

Most lava moves slow enough

for people to escape it.

When it explodes from a volcano, runny lava

may form cow-pie “bombs” that splat

into rough pancake shapes.

When the Icelandic volcano Eyjafjallajökull erupted

in 2010, ash forced airports as far away as mainland

Europe to shut down for almost a week.

Water warmed by

volcanoes is used to

heat homes in Iceland.

Rich volcanic soil

is excellent for

growing crops.

Volcanoes eject bombs—

semi-molten pieces of lava—

and solid lava chunks called blocks.

A pyroclastic flow is a fast-moving mix of hot gas, ash, and rock that can destroy everything in its path.

A volcano

can flatten

a forest.

Lava that hardens into a smooth,

ropy surface is called pahoehoe

(paw-HOE-EE-hoe-ee).

Volcanic bombs and blocks can be as

small as your fist or as big as a house.

Earth’s largest land volcano, Mauna Loa

in Hawaii, U.S.A., is more than 10 miles high

from its base on the seafloor to its top.

CHAPTER 1

Besides Stromboli,

a volcano erupts

somewhere on Earth

EVERY WEEK.

Stromboli has been spewing

gas and spitting molten rock

for more than 2,000 years! It is one of

Earth’s most active volcanoes. Full

eruptions can occur from only minutes

to hours apart.

Volcanoes begin deep
