F • looding happens during: • heavy rains • when rivers overflow • when snow melts too fast • when dams or levees break. • when ocean waves come onshore
Flooding may be only a few inches of water or it may cover a house to the rooftop. • Floods that happen very quickly are called flashfloods. • Flooding is the most common of all natural hazards.
Linda's Story.... Linda looked out the window. "Is it ever going to stop raining, Grandma?" she asked. It had been raining hard for three days. Most of the time, the Acorn River was a nice, slow river, Now it was full and raging. Linda waited for good news but still the rain fell, even past dinner.
Linda's Story.... That night the weatherman on the television was serious. "The river is approaching flood stage," he said. "The Army Corps of Engineers is sandbagging along the shore.“ Grandma told them the sandbags would be stacked along the river to keep the water from flowing into the town.
Linda's Story.... Grandma said, "The water can rise very fast in a flash flood. We need to be ready to evacuate, just in case." "Pack a suitcase with things for a few days," said Grandma. What do you think Grandma will pack in the suitcase?
E • arthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. • Earthquakes can be felt over large areas although they usually last less than one minute.
Earthquakes cannot be predicted. • You will notice an earthquake by the gentle shaking of the ground or you may notice hanging objects wobbling on shelves and a low rumbling noise • The intensity of an earthquake can be measured on the Richter scale.
John's Story.... Once upon a time there was a little boy named John. One night, as he was lying in his bed, his whole room began to shake. And then it rattled. John could see his picture frames on the wall start falling to the ground. There was a low rumbling noise which became louder and louder.
John's Story.... This experience scared Leonard very much because he had never been in an earthquake before. And even after the earthquake had stopped he was still very afraid because he wasn't sure what he was supposed to do. What is John supposed to do the next time there is an earthquake?
ornadoes are nature’s most violent storms. • They come from powerful thunderstorms and appear as rotating, funnel-shaped clouds. • They cause damage when they touch down on the ground.
Tornadoes can form any time of the year, but the season runs from March to August. • Tornadoes must always be taken seriously and can be very dangerous -- sometimes even deadly. • The ability to predict tornadoes is limited.
Tracy's Story.... It started as a regular day and I looked out the window and clouds appeared. They were regular clouds, except that they moved very quickly across the sky. Ten minutes later, a thunder cloud was building. The wind picked up and was coming from the southeast at about 45 to 50 miles per hour.
Tracy's Story.... It started to hail and rain really hard and I looked up at the sky and saw a vortex. During the tornado, I had to hide in the underground basement which was about five feet deep. What is a vortex and how does a tornado come about? Activity Sheet Three
