They have met seismic fortification criterion and weathered the Jiuzhaigou earthquake. The number of collapsed buildings and buildings with serious damage are very low, significantly reducing casualties."

Storyline


An intensity map of the 7.0-magnitude earthquake that jolted Jiuzhaigou County in southwest China's Sichuan Province last Tuesday was released at a press briefing at the local disaster relief headquarters on Saturday afternoon.

The earthquake's intensity is a number, written as a Roman numeral, quantifying the effects of an earthquake on the earth's surface, humans, objects of nature and man-made structures on a scale from I (not felt) to XII (total destruction).

The map shows that the largest seismic intensity was Ⅸ (violent), and the gross area with seismic intensity above Ⅵ (strong) reached 18,295 square kilometers, affecting eight counties in Sichuan Province and northwest China's Gansu Province.

"The maximum seismic intensity of the Jiuzhaigou earthquake is IX. The isoseismal line generally presents a north-north-west trend. The area above VI has amounted to 18,295 square kilometers," said Lei Jiancheng, the deputy director of the Sichuan Earthquake Administration.

Lei explained that the earthquake affected eight counties including Sichuan's Jiuzhaigou County, Ruoergai County, Hongyuan County and Songpan County of Aba Tibetan and Qiang Autonomous Prefecture, as well as Pingwu County of Mianyang City. Gansu Province's Wenxian County in Longnan City and Zhouqu County and Diebu County in Gannan Tibetan Autonomous Prefecture were also affected.

Despite the earthquake's high magnitude and deep focal depth, the number of injuries and deaths, as well as the degree of damage to buildings caused by the earthquake in Jiuzhaigou, were far less serious than the 7.1-magnitude earthquake in Yushu Tibetan Autonomous Prefecture of northwest China's Qinghai Province in 2010 which killed 2,679 people.

One reason why the Jiuzhaigou earthquake resulted in less damage and fewer casualties is because the earthquake happened in an area with low population density. Another reason is because new buildings have been constructed for seismic resistance. Moreover, local authorities have strengthened the capacity for disaster risk reduction in recent years.

"The buildings in the affected area have a high degree of seismic fortification and good anti-seismic behavior, especially the new buildings constructed after the Wenchuan Earthquake of 2008. They have met seismic fortification criterion and weathered the Jiuzhaigou earthquake. The number of collapsed buildings and buildings with serious damage are very low, significantly reducing casualties," said Lei.
