Italy earthquake caused 6.2 GDP loss of nearly 1% why so serious? U.S. stock market center: exclusive national industry sector stocks, premarket after hours, ETF, real-time quotes of local time on August 24, 2016, the central city of Italy and the local earthquake struck amath. Source: visual Italy, China, the central region at 3:36 local time 6.2 earthquake occurred, shaking lasted about 20 seconds. Then again in the same place a 5.5 magnitude aftershock. According to the U.S. Geological Survey (USGS) analysis, the epicenter is located in Perugia (Perugia) about 76 km southeast, focal depth of about 10 km, is a very shallow earthquake. According to Broadcasting British Corporation (BBC) reported that as of midnight local time on August 24th, the earthquake has killed at least 159 people were killed and 368 injured. The United States Geological survey released orange and red warning of casualties and economic losses, and predicted that the earthquake will cause serious damage to personnel and the economy. After the earthquake, the U.S. Geological Survey initially expected, based on past experience, the death toll of the earthquake may be between 100 to thousands of people, economic losses could reach 1 billion to 10 billion U.S. dollars, resulting in the loss of nearly 1% of Italy GDP. The magnitude of the earthquake is relatively low, but why is it so serious? Plate boundary, resulting in multiple earthquakes. From the point of view of geology, the peninsula Italy is belong to the earthquakes, geological faults almost throughout the whole country, the Richter 5 earthquake, 6 from the probability that be not at all surprising. West of the peninsula belongs to the Eurasian plate, South African plate, the latter at an annual rate of 2 cm northward. In addition, there is a peninsula east move toward the Northeast Adria plates, several large plates or extrusion stretching may lead to geological activity, the energy will be accumulated to a certain extent the outbreak of the earthquake. BBC said, in the eastern part of Italy, between the peninsula and Sardinia Corsica at its Anhai years is slowly opened. Scientists believe that this is conducive to the Apennine Peninsula through the mountains of central Italy expansion. In the west of Italy in the Adriatic Sea, there is some evidence that the crust in Italy to the direction of subduction, but this view is controversial. Italy first encounter a large earthquake in May 2012, is located in the northern part of the country at that time, Emilia – Rome Nirvana region within 10 days has occurred 6 and 5.8 earthquake, killing 24 people, 15 thousand people have been displaced. Compared with earthquakes in the southern part of the country, the earthquake occurred in the north also attracted the attention of geologists. At that time, Dr. John Elliott of University of Oxford earthquake and geological observation and model center that Emilia – Rome, Auvergne earthquake is the result of the expansion section, is a reverse fault (thrust faulting) earthquake. When some small faults are involved, this type of fault often forms a blind thrust fault (blind thrust faulti1)相关的主题文章:
