Nepal Earthquake: An on-going crisis
Learning Objective: To explain the causes
and impacts of the Nepalese earthquake
Where was the earthquake?
So what caused the earthquake to
happen?
How could this cracked egg be a clue
as to what caused the earthquake?
So what plate boundary was the
earthquake on?
Collision Plate Margins
The plates are
being forced
together at great
pressure so the
rocks crumble
together and
form massive
mountains, like
the Himalayas
where the
earthquake was.
How are earthquakes measured?
The Richter Scale
• The power of an
earthquake is called the
magnitude.
• Earthquakes are measured
by a seismometer and
graded according to the
Richter Scale.
This earthquake measured 7.8
on the Richter scale
The focus and the epicentre
• Earthquakes start at the
focus.
• The epicentre is the point
on the Earth’s surface above
the focus, and is the first
place to shake.
• The focus can be shallow or
deep.
Challenge
What effect will the position
of the epicentre have on the
damage caused by the
earthquake?
Are all earthquakes the same?
What does this have to do with earthquakes?
- I think that this relates to earthquakes
because . . .
- I think the pencil is . . .
- I think the point where the pencil snaps
How are earthquakes formed?
• Underground tectonic plates push past each
other, building up pressure.
• This pressure is suddenly released along faults
(cracks in the crust), sending out a huge pulse
of energy.
• This travels out in all directions as earthquake
waves.
Challenge: How does this relate to the pencil?

What has been the ‘Relief Effort’ do
far?
What do you think we mean by ‘Relief effort’?
This is the response and help offered by
countries around the world.
