subject: Expert: Chile Normal Seismic Activity Limited Impact On China - Chile Earthquake, Seismic Hazards, [print this page] Jihai, the earthquake in Chile and other places, the Beijing 6 am beyond Southwest region in the Sumatra earthquake of magnitude 7.1, which makes many people feel insecure. In response, seismic experts, the China Earthquake Networks Center, said Liu Jie, director of forecasting the current global seismic activity remained at normal levels, there is no need to worry too much. Liu Jie believe that global access to strong earthquake active, would have certain effects on our country. However, recent earthquake itself, limited impact on China.
He said, Haiti is more localized seismic performance of plate activities, associated with less global. The Chile earthquake, according to the China Seismological Bureau The results show that Chile earthquake and seismic activity in China mainland significant correlation does not exist
Different reasons Liu Jie said, Haiti, Chile and the Sumatra earthquake for different reasons, there is no necessary connection between each other. Haiti, the occurrence of the earthquake is due to the North American plate and the resulting interaction between the South American plate; Chile earthquake Pacific Plate Nazca Plate and South American Plate Collision Cause; and 6, near the earthquake occurred in Sumatra since 2004 is 9.1 earthquake in Indonesia, near the active performance of the regional geological activity. Since 2004, the Indonesian earthquake, in the vicinity for more than eight earthquakes have occurred 4 times and more than magnitude 7 earthquake.
From the analysis of their different reasons, you can see it a few times does not necessarily see the connection between the earthquake. Liu Jie said this several times farther away from the earthquake occurred, and is caused by the effects of different sections, each other, there is no obvious cause and effect.
Frequency remains normal The recent earthquakes too frequent questions, said Liu Jie analysis, as of now, the global total of more than magnitude 7 earthquakes 5, which on January 2 times, 2 February second, March 1 times. Last year in November and December there were more than magnitude 7 earthquake 1. Or 5 months, there were more than magnitude 7 earthquake 6.
According to statistics, the global average annual occurrence of more than magnitude 8.0 earthquake in 1 to 2 times more than magnitude 7 earthquake in an average of 18 times. So far, the global seismic frequency is still within the normal range.
Jie believe that a few earthquakes can indeed show that the Central Pacific plate at the more active state. Meanwhile, global earthquake also more active.
"2004 earthquake in Indonesia, the world entered a very large earthquake of 8.5 or more active period." Said Liu Jie, 8.5 earthquakes in Indonesia in 2004 after a major earthquake occurs frequently, It should be said from the beginning that time on the earth's plate movement entered the active phase Earthquake Chile earthquake is active in the performance of plate motion.
Limited impact on China Jie that the world has entered a period of strong earthquake activity, will have certain effects on our country. However, recent earthquake itself, limited impact on China.
He said, Haiti is more localized seismic performance of plate activities, associated with less global. The Chile earthquake, according to the China Seismological Bureau The results show that Chile earthquake and seismic activity in China mainland There is no obvious correlation.
Report said the 8.8 earthquake in Chile Chile's central region. In the 8.8 before the earthquake, since 1900, have occurred in central and southern Chile 4 7.8 earthquakes, the results show that the occurrence of a major earthquake in the region and the Chinese mainland between seismic activity relationship is not obvious, will not affect the seismic activity in China mainland.
