Earthquake

Every 30 seconds there is an earthquake. But don't worry because most cannot be felt. Only a few big ones hurt people.

Many earthquakes happened in China, such as the big one in Sichuan. Thousands of people died in it. So it's important to know what to do when one hits. Here are some tips on how to stay safely in an earthquake.

If you are indoors during an earthquake, hide under a desk. Stay away from windows and anything that could fall on you.

If you are outdoors, move to a clear place. Try to be away from trees, signs, buildings and streetlights. These could fall on you.

If you are in a shop and far from the door, don't try to run to outside and rush for exits. Everyone will be doing that and you'll find it hard getting out. Don't get into a lift during an earthquake. Just hide under some strong covers near you.

When an earthquake has ended, be careful because after-shocks may still happen. These are just as dangerous as the earthquake itself. So stay under the desk until you make sure it's safe to get up.

If you are at home and you smell gas, open the windows and get out of the building as quickly as you can. A gas line in your house may be broken. This could be very dangerous.

Weather

Different weather makes people feel different. It influences health, intelligence and feelings. In August, it's hot and wet in the southern part of the USA. People there have heart trouble and other kinds of health problems during this month. In the northeast and the middle-west, it is very hot sometimes and very cold sometimes. People in these states have more heart trouble after the weather changes in February or March.

The weather can also influence intelligence. For example, in a 1983 study by scientists showed that the IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often do worse on exams in the hot months of the year (July and August).

Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold these months. They might feel unhappy during cold weather. But big people may have a hard time in hot summer. At about 18℃, people become stronger.

Low air pressure may make people forgetful. People leave more bags on buses and in shops on low-pressure days. There is "good weather" for work and health. People feel best at a temperature of about 18℃.

Are you feeling sad, tired or forgetful today? It may be the weather's fault.
