Emergency workers during floods
Floods occur when a river overflows its banks because
of an unusually high water level. Because floods usu-
ally happen after a severe rainstorm or after a sudden
melting of snow, floods rarely catch people by surprise.
There is often enough time for people to leave their
homes and for farmers to move their animals and cars
to higher ground. People can build up the riverbanks
with sandbags to limit the amount of water that will
overflow. Sometimes, however, a river can rise higher
and faster than expected.
When this happens, emergency workers monitor
the water level and warn people to leave their houses.
They do this by broadcasting messages on the radio or
by warning people in person. People who do not leave
their houses may have to climb onto the roofs of their
houses to escape the swirling water and to wait for
rescue. Emergency workers pick the people up in boats
and take them to evacuation camps on higher ground.
After the emergency has passed, the cleaning up
begins. Rubbish on the roads has to be cleared away.
Roads that have been damaged need to have signs put
up to warn drivers. Some roads may even need to be
closed until they are repaired. Bridges are examined to
see if they are still safe after the battering they have taken
from the force of the flood waters.
Emergency workers during
volcanic eruptions
A volcanic eruption can cause a lot of damage to the
surrounding areas. The blast of hot, choking gases and
ash can make the day seem like night and kill people
and animals. The lava that flows down the mountain
can destroy the countryside.
Some volcanoes give signs of volcanic activity for a
long time before an eruption occurs. Steam leaks out of
cracks in the earth's surface, and the mountain begins
to bulge and crack. Scientists monitor these signs so
that they can warn people to leave their homes if the
volcano is going to erupt. They use special machines
to help them monitor the changes in the earth’s crust.
Using the information, the scientists can predict if there
will be an eruption and where it will happen. Scientists
who monitor the activity of a volcano are in danger if
the volcano erupts.
During and after a volcanic eruption, emergency
workers are busy evacuating people from the area,
searching for the survivors and rescuing people. Emer-
gency workers repair and restore the electricity, tel-
ephone, water and gas services as quickly as possible.
One of the biggest jobs for emergency workers after a
volcano has erupted is to clean up the ash.
