The major city closest to
Krakatau is Jakarta, that is
about 80 miles of distance
from it.
This volcano is on the
Australian plate under the
Eurasian plate.
Krakatau is located in
the Sunda Strait
between the islands of
Java and Sumatra in
Indonesia.
The summit elevation of
the Krakatau volcano is
813 m (2,667 ft.)
The longitude of this volcano is
105.423 degrees East (105
degrees 25’ 22’’)
The latitude is 6.102 degrees
South (6 degrees 6’ 6’’ South)
Krakatau is a Caldera volcano which is
the largest kind of volcano on this
Earth.
These kinds are the most
powerful and dangerous, and
its shaped is like an inverse
volcano.
Caldera volcanoes also have
huge magma chambers
beneath the ground from high
pressures of trapped gasses.
The last known eruption of the
Krakatau volcano was in April 2009.
The type of eruption this volcano
goes through is explosive.
A lahar is a slurry of volcanic material and
water. They are very thick but really quick.
Most of the time, they are very
deadly.
“The ash cloud grows and
billows up as lava bombs roll
down.”
Pyroclastic
(meaning "fire
fragmented") refers
to broken-up rocks,
pumice, ash, and
other bits of material
that are formed in a
volcanic eruption.
The definition of
tephra is materials
of all types and
sizes that are
erupted from a
crater or volcanic
vent and deposited
from the air.
This
picture is
an
example
of how
much
ash is
created
when
Krakatau
erupts.
A fumarole is a small hole
or vent in the Earth's crust
found near volcanic areas,
from which stream or
gases shoot out.

In the year of 1883, there was a major
climate change. When Krakatau
erupted in this year, there was a huge
amount of volcanic dust that went into
the atmosphere. When this happened,
it acted like a solar radiation filter,
which limits the amount of light that
hits the Earth. One year later, the
global temperature lowered about 1.2
degrees centigrade. The global
temperature didn’t go back to normal
until 1888!!
