(A) Emergency workers during floods
Floods occur when a river overflows its banks because of an unusually high water level. Because floods usually 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.
(B) Emergency workers during volcanic eruptions
A volcanic eruption can cause a lot of damage to (he 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 (he 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. Emergency workers repair and restore the electricity, telephone, 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.
