China destructive earthquake will not occur
China Seismological Bureau, scientists yesterday introduced in 2010, global earthquake frequency is indeed slightly above average, but in the meantime is
still difficult to assert that the world will enter earthquake-prone period. To analyze the present situation, the global earthquake likely to continue, but most occur in the Pacific Rim, China's devastating earthquake in China not going to happen with an air jordan. Video: Chinese experts say the recent global seismic activity is normal. Source: Shenzhen Satellite TV, "High Noon 30 minutes" Reporter: Why did the recent global magnitude 7 earthquakes so frequent? Seismic experts: since 1900, the global annual average of more than magnitude 7 earthquake occurred 18 times, eight times more than an earthquake, but the earthquake time is very uneven, and some time an earthquake with an air jordan 1, and some time an earthquake is more sparse. Since 2010, as of March 6, on the global magnitude 7 earthquake occurred five times, slightly higher than average, taking into account the distribution of earthquakes in time on the uneven nature of the distribution is still normal, is the process of the Earth's crustal movement Earthquake the activities of a normal fluctuation phenomenon. Since January 13 Haiti 7.3 earthquake and the February 27 Chile 8.8 earthquake caused a huge social impact, and therefore the recent worldwide earthquake activity is more cause for concern. Reporter: Does the world into the earthquake-prone period? Earthquake experts: Since entering the 21st century, the world's eight more than the frequency of earthquakes increased significantly compared with the previous decades, similar to the first half of the last century earthquake activity features, namely the so-called global seismic activity "Rise of cycle" feature. If this "century cycle" does exist, the current context of strong earthquakes in this global phenomenon more likely to continue, most of the earthquake will occur in the circum-Pacific seismic belt. Reporter: The last time the world's earthquake-prone What is the period? What is the specific circumstances? Earthquake experts: 8.5 or above on the global great seismic activity, the last time the world's active period of strong earthquakes in the period 1950-1965, the period over the world in nine earthquakes three times, the Kamchatka Peninsula in 1952 were 9.0 magnitude earthquake, 9.5 earthquake in Chile in 1960 and the 1964 earthquake in Alaska, 9.2; 8.5 earthquake more than seven times, except one took place in China's Tibet Zayu, the remaining 6 occurred in the circum-Pacific seismic belt. Reporter: The recent earthquake in China there have been some reason for that? Earthquake Expert: China is the world's earthquake-prone countries and mainland China with an average of 145 Michael air Jordans and four earthquakes (12 times / month), 20 5 quake ,3-4 times 6 earthquake. In addition, the average twice every three years, a magnitude 7 earthquake will occur. At present seismic activity in Mainland China at the average level of seismic activity is a normal release of energy. |
