Loma Prieta earthquake, 1989
At five in the afternoon on October 17, 1989 the San
Andreas fault system in northern California had its first
major quake since 1906. Focus of the earthquake In the
Loma Prieta hills 60 miles south of San Francisco.
Pacific Plate (to the west) and the North American Plate
(to the east).
Conservative Plate boundary- plates sliding past each
other (diagram?)
As the plates move, stress builds up along faults. When
this stress is released, the blocks or plates move and an
earthquake occurs. There are many fault zones along
the San Andreas Fault.

San Francisco Quake
• The quake was responsible for 62 deaths,
3,757 injuries, and over $6 billion in damage.
Over 18,000 homes and 2,600 businesses
were damaged and about 3,000 people were
left homeless.
Redo the question…..
1. Explain the causes of the volcanic eruption or
earthquake (6)
Water
Although on a superficial level many were able to
do this too often comparisons with LICs led to
sweeping generalisations of lack of toilets and no
cars; centres must be careful to avoid this. Some
candidates knew that the UK was a HIC but
couldn't find reasons to show why the water use
was HIC. Good answers wrote about HICs using
luxury water consuming devices or LIC use as
being mainly for subsistent purposes due to poor
access.
Question 6(a) (iii)
Many candidates were able to identify two uses,
and common answers included drinking,
cooking and brushing teeth. A few candidates
mistook the question and focused on
industrial or agricultural uses.
Describe the distribution of rainfall in
Great Britain shown on 6b
Describe the distribution of rainfall in
Great Britain shown on 6b
This question required candidates to describe
the rainfall distribution in Great Britain.
Candidates tended to simply write about each
region without describing the distribution.
Good answers found patterns such as the west
having more rainfall than the east. Answers
which used evidence to support were also
high scoring.
There is an imbalance between water
supply and population in Great Britain.

iii. Outline other factors that can affect
world population density
