Caus CAS rearcher at the Institute of Geology and Geophysics, the Qinghai-Tibet Plateau Rearch Wang Wenchuan 27 pairs more familiar with regional geological structure, in early May has been Wenchuan area. He analyzed that Wenchuan earthquake
occurred in the southeast edge of the Qinghai-Tibet Plateau, western Sichuan Longmenshan the center, located in Wenchuan - Timor-mao on the fault zone.Indian Ocean plate northward movement, squeezing the Eurasian plate, causing uplift of the Qinghai-Tibet Plateau. At the same time in the uplift of the plateau, also eastward movement, squeezing the Sichuan Basin. Sichuan Basin is a relatively stable block. Although the main looks Longmenshan tectonic activity is not strong, but the stress may be stored in the process of accumulation to a certain extent, the crust will break down, so the earthquake. The U.S. Geological Survey also relead the news that the earthquake's epicenter and focal mechanisms and Longmenshan fault or a related movement of tectonic fault in line, the earthquake is a thrust to the northeast of the campaign results. From the mainland scale, Central Asia and East Asia, the ismic activity is due to the Indian Ocean plate collision of the Eurasian Plate. Southern California Earthquake Rearch Center, Professor Li Yonggang told Xinhua, Longmenshan fault zone is earthquake-prone region of active faults, from the Qinghai-Tibet Plateau deep eastward flow of material disruption to the Sichuan Basin, the upward
movement, which both border For the fault plane. If the fault movement a few centimeters a year, once every 50 to 70 meters, the accumulation of stress and energy can be generated from a magnitude 7 earthquake above. As the source shallow, and focal mechanism for the eastward thrust of the campaign, coupled with soft soil earthquake zone, ismic waves will spread eastward very long, making far to Shanghai and Beijing and other cities have generally felt.
British Geological Survey earthquake monitoring and information rvice center director Brian • Bapu Di in the Xinhua News Agency reporters Dian Huacai and Fang Shiyue, from the geological structure, the earthquake and the Himalayan collision zone on, "is clearly the Northeast - to the Southwest Longmenshan fault zone in the compression of the result. " France's Institute of Geophysics, geologist Paul • Daboniye the media said about 5,000 years ago, the Indian Ocean plate drift northward, collided with the Eurasian Plate after diving to the latter below, which formed the Qinghai-Tibet Plateau. Qinghai-Tibet Plateau is still squeezed by the two plates, making the Qinghai-Tibet Plateau and the surrounding areas into intensive earthquake zone
State Council Notice
For the expression of the people of all nationalities of the four Chuan Wenchuan earthquake victims compatriots deep condolences, the State Council decided in 2008, from 19 to 21 May as a national mourning. In the meantime, the national and foreign institutions Xiaban Qi Zhi Ai, and stop public recreational activities, the Foreign Ministry and China's embassies and consulates t up condolence book. At 14:28 on May 19, people across the country and obrve silence for three minutes, then cars, trains, ships whistle, air defen alarm is ringing.
Earthquakes strike suddenly, violently and without warning. Identifying potential hazards ahead of time and advance planning can reduce the dangers of rious injury or loss of life from an earthquake. Repairing deep plaster cracks in ceilings and foundations, anchoring overhead lighting fixtures to the ceiling, and following local ismic building standards, will help reduce the impact of earthquakes.
Six Ways to Plan Ahead
1. Check for Hazards in the Home
o fortunesRepair defective electrical wiring and leaky gas connections. The are potential fire risks.
barber是什么意思o Secure a water heater by strapping it to the wall studs and bolting it to the floor.

o Store weed killers, pesticides, and flammable products curely in clod cabinets with latches and on bottom shelves.
2. Identify Safe Places Indoors and Outdoors

cartier是什么意思o Against an inside wall.
o In the open, away from buildings, trees, telephone and electrical lines, overpass, or elevated expressways.tyrant
3. Educate Yourlf and Family Members staffing
o Contact your local emergency management office or American Red Cross chapter for more information on earthquakes. Also read the "How-To Series" for information on how to protect your property from earthquakes.
o Teach children how and when to call 9-1-1, police, or fire department and which radio station to tune to for emergency information.
o Teach all family members how and when to turn off gas, electricity, and water.
4. Have Disaster Supplies on Hand
o Flashlight and extra batteries.
o Portable battery-operated radio and extra batteries.
o thermosNonelectric can opener.
o Esntial medicines.
o Cash and credit cards.
o Sturdy shoes.
5. Develop an Emergency Communication Plan
o In ca family members are parated from one another during an earthquake (a real possibility during the day when adults are at work and children are at school), develop a plan for reuniting after the disaster.
o Ask an out-of-state relative or friend to rve as the "family contact." After a disaster, it's often easier to call long distance. Make sure everyone in the family knows the name, address, and phone number of the contact person.gowest
6. Help Your Community Get Ready
o Publish a special ction in your local newspaper with emergency information on earthquakes. Localize the information by printing the phone numbers of local emergency rvices offices, the American Red Cross, and hospitals.
o Conduct a week-long ries on locating hazards in the home.
o Provide tips on conducting earthquake drills in the home.
