Types of volcano
Shield Volcano
Shield volcanoes are often
characterised by their gently
sloping sides and thin, runny
lava
...
Their name comes from
the appearance of the
volcano, which looks like a
soldier’s shield lying on the ground
...
It is 1,247m high and last erupted in January 1983
...
Eruptions
from these kind of volcanoes
tend to consist of pyroclastic
flow (a mixture of hot steam,
ash, rock and dust) rather than
just lava flow
...
This makes it very hard to outrun and escape these eruptions, and the
ash and dust can also get into your lungs and cause asphyxiation or rock can fall
and cause head injuries
...

Example: Krakatoa, which is 813m high and is a volcanic island in Indonesia
...
It killed around 36,000 people and changed temperatures globally, with

many dying as a result of thermal injury or in the following tsunami that was triggered
by the eruption
...

Hotspot
volcanoes are
found in
anomalous
locations,
because they
do not appear
at plate
boundaries like
most
volcanoes
...
If the Yellowstone
Caldera erupts then it has the potential to literally end the world, meaning that it’s
activity is very closely monitored by scientists
...
Precursors to these super
eruptions include multiple small earthquakes around the site (called a “seismic
swarm”) and rapid ground deformation
