In countries where earthquakes are particularly abundant, many
precautions have been set up to prepare the region for the eventuality of
an earthquake. Children are educated about what to do if an earthquake
occurs and
government has an official plan to carry out in such a case. The picture
that is to the left shows a poster that is aimed at the civilians living in
Singapore. Many regions at risk from earthquakes have such notices that
are designed to minimize the death toll during an earthquake. In Japan,
the 1st September is nationally known as `Disaster Day'. This is the
anniversary of the deadly earthquake that occurred in Tokyo in 1923,

killing 155,000 people. On `Disaster Day' the residents of Japan practice
an earthquake drill which they must use in the case of an emergency.
Many areas that are most at risk from seismic activity have manufactured
`Earthquake Proof
Buildings'. A famous
example is the Transamerica
Pyramid (left). This massive
building, located in San
Francisco, USA, is
structurally designed to
withstand earthquakes.…read more

There are many other types of simple bracing that can also help protect a
building from earthquakes. These include the reinforcements shown
Some buildings are built to be `movement resistant'. This allows the
building to bend during an earthquake rather than snap. Other methods
of reinforcing buildings are Shear Walls and Horizontal Trussing. One
effective method is to use Rubber Bearings to allow the foundations of a
building to move in the event of an earthquake.…read more

earthquake and therefore will reduce
the overall death toll. This is very useful in MEDC countries where the
buildings are more valuable.
The governments of earthquake-prone regions also have a carefully
formulated plan to follow in the event of such a disaster. If an earthquake
can be detected before it starts, people are evacuated or warned and
power stations can be shut down. However, predicting earthquakes is
costly and only richer regions of MEDCs can afford to research such
things.…read more
