The Japan Meteorological Agency (JMA) defined the earthquake magnitude. The earthquake was named “the 1995 South Hyogo Prefecture Earthquake” (or the 1995 Hyogoken Nanbu Earthquake) by JMA.

Store one weeks food for each person. Earthquake survival supplies include a radio receiver, a torch, extra batteries, first-aid supplies, a spade, a tent, some rope, and warm clothing.4. What should be a major emphasis for all government programs and earthquake-related research projects?Education concerning how to survive an earthquake should be.Text Structure AnalysisSummary: At present, people cant be able to know when an earthquake is going to happen and how bad it will be. However, in both Japan and China, people have long believed that earthquakes can be forecast, such as by watching animals for warning signs of earthquakes. In order to decrease the destruction of property caused by earthquakes, people begin to use new materials and new technologies to construct buildings. Besides, people should have supplies of water and food at home and at work. Experts also have some suggestions about how to deal with earthquakes.Devices for Developing 1.Questioning (设问法)The title “How to Prepare for Earthquakes” on, the author guides the reader toward a better understanding of his article through a list of direct or indirect questions, thus reminding the reader of what is to follow what he is to give his ink to next. (Para.1; Para.2; Para3-6)1. When is an earthquake going to happen? (Para. 1)Para. One is about some examples of how to predict earthquakes.2. How to prevent the great destruction of property caused by earthquakes? (Para. 2) Para. Two deals with how to make building structure so strong as to withstand the power of earthquakes.3. How to prepare for the possibility of a great earthquake? (Para. 3-6)Paras. Three to Six are about how to prepare ourselves for the possibility of a great earthquake. 2. Deduction (演绎法)Another characteristic writing technique that runs throughout the writing is a general statement supported by details.Statement：Ideally, people would like to know when an earthquake is going to happen and how bad it will be. (Para. 1)Details: 1. Scientists have wired the Earth and sea to detect movements.2. People have traditionally watched animals and plants for warning signs of earthquakes. 3. Experimental data show that the amount of radon in the water under the surface of the Earth waxes before an earthquake.Statement: People would also like to be able to prevent the great destruction of property caused by earthquakes. (Para. 2)Details: 1. Many new structures are built with an I-joint, which appears to be the most durable type of joint.2. Architects design buildings so that their columns and horizontal beams are of equal strength, and vertical support columns are inserted deep into solid soil.3. Many new houses have relatively light roofs and strong walls.4. Concrete pillars for highway bridges that previously only had steel rods inside are now enclosed in steel.Statement：Besides working to improve building structures, people in areas where earthquakes are common need to prepare for the possibility of a great earthquake. (Paras. 3-6)Details: 1. Regularly check and reinforce your homes, place heavy objects in low positions, attach cupboards and cabinets to walls, and fasten door. (Para. 3)2. Have supplies of water and food at home and at work. Keep supplies such as a radio receiver, a torch, extra batteries, first-aid supplies, a spade, a tent, some rope, and warm clothing. (Para. 4)3. Keep a fire extinguisher and some proper tools to turn off gas and water lines. Arrange an auxiliary cooking and heating source. Keep a pair of heavy shoes or boots to protect your feet. (Para. 5)4.Have earthquake emergency plans. Make arrangements in case of an earthquake for family members to leave the area in time, to meet at a place, to communicate with each other or to check in with a far-away friend. (Para. 6)Conclusion：Even if prediction becomes possible, people still have to do their best to prevent disasters by improving building structures and by being personally prepared. (Para. 7)Main Idea of the text and each partMain idea of the text:The essay is centered on the main theme How to predict, prevent, and prepare for earthquakes. Part I (Para.1): This part is about how to predict an earthquake. Exemplification (举例法)Part II (Para.2): This part deals with how to prevent the great destruction of property caused by earthquakes. Reasoning（推理法）: Addition（递进法） Part III (Para.3-6): This part is about how people need to prepare themselves for the possibility of a great earthquake.Addition（递进法）Part IV (Para.7): This part serves as a conclusion: even if prediction becomes possible in the future, people still have to do their best to prevent disasters by improving building structures and by being personally prepared.
