Teachers and fellow students, As we all know, an 8.0 earthquake broke out at 2:28pm on May 12th in Wenchuan, Sichuan Province.
It’s reported that the earthquake was so strong that it has caused 68,109 deaths and 364,552 people were hurt. Many houses and schools were destroyed and as a consequence, more than five million people are living a hard life now. Just imagine how the stud名言警句ents there need help and that schools should be built so that students can return to classes soon.
People all over the world are trying their best to help them, not excepting us. Here Students’ Union calls on everyone to give away your old clothes and pocket money and bring your used books, mp3s or something else to sell in the bring-and-buy sale. All the materials and the money to be collected will be sent to the earthquake stricken areas as soon as possible. My fellow friends, “blood is thicker than water”. Please donate your love and give out your hands without hesitation.
We believe miracles can be created, a great many lives will be saved and the harmonious society is sure to be achieved. That’s all. Thank you!
An earthquake is a shaking of the ground caused by the sudden breaking and shifting of large sections of Earths rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. A severe earthquake may release energy 10,000 times as great as that of the first atomic bomb. Rock movements during an earthquake can make rivers change their course. Earthquakes can trigger landslides that cause great damage and loss of life. Large earthquakes beneath the ocean can create a series of huge, destructive waves called tsunamis that flood coasts for many miles.
Earthquakes almost never kill people directly. Instead, many deaths and injuries in earthquakes result from falling objects and the collapse of buildings, bridges, and other structures. Fire resulting from broken gas or power lines is another major danger during a quake. Spills of hazardous chemicals are also a concern during an earthquake.
The force of an earthquake depends on how much rock breaks and how far it shifts. Powerful earthquakes can shake firm ground violently for great distances. During minor earthquakes, the vibration may be no greater than the vibration caused by a passing truck.
On average, a powerful earthquake occurs less than once every two years. At least 40 moderate earthquakes cause damage somewhere in the world each year. About 40,000 to 50,000 small earthquakes--large enough to be felt but not damaging--occur annually.
Dear friends ：
Im sorry to hear that an earthquake happened to your hometown. The earthquake destroyed your hometown. Lots of houses fell down and some of you高考作文 cant see your families any longer.

a strong earthquake struck wenchuan, sichuan province on may 12, 2008. people in disaster-stricken area have suffered a lot. misery of losing home as well as family members have thrown them into deep sorrow. seeing the photos on the internet and newspapers, i kept asking myself, “what can i do to help them lessen their burden?”
like many other classmates, i’ve donated all the money i save and i’ve also given away many books and stationary in order to help those children who now aren’t able to go to school. besides, i’ve written some letters to the kids at my age, trying to encourage them and cheer them up.

An earthquake is a tremor of the earths surface usually triggered by the release of underground stress along fault lines. This release causes movement in masses of rock and resulting shock waves. In spite of extensive research and sophisticated equipment, it is impossible to predict an earthquake, although experts can estimate the likelihood of an earthquake occurring in a particular region.
In 1935, American seismologist Charles Richter developed a scale that measures the magnitude of seismic waves. Called the Richter scale, it rates earth tremors on a scale from 1 to 9, with 9 being the most powerful and each number representing an increase of ten times the energy over the previous number. According to this scale, any quake that is higher than 4.5 can cause damage to stone buildings; quakes rated a magnitude of 7 and above are considered very severe. A less-known scale, the Mercalli scale , was devised by Italian seismologist Giuseppe Mercalli to measure the severity of an earthquake in terms of its impact on a particular area and its inhabitants and buildings.
Some earthquakes are too small to be felt but can cause movement of the earth, opening up holes and displacing rocks. Shock waves from a very powerful earthquake can trigger smaller quakes hundreds of miles away from the epicenter. Approximately 1,000 earthquakes measuring 5.0 and above occur yearly. Earthquakes of the greatest intensity happen about once a year and major earthquakes occur about 18 times a year. Strong earthquakes occur about 10 times a month and moderate earthquakes happen more than twice daily. Most earthquakes are not even noticed by the general public, since they happen either under the ocean or in unpopulated areas. Sometimes an earthquake under the ocean can be so severe, it will cause a tsunami, responsible for far greater damage.
The greatest danger of an earthquake comes from falling buildings and structures and flying glass, stones and other objects.
