New seismic zoning map in place since June, Yunnan new earthquake resistance standards

News Agency, Kunming, May 12 (Xinhua Hu Yuanhang) the 12th from the Yunnan Provincial Seismological Bureau held "earthquake disaster prevention and reduction" press conference was informed that, of the new fifth-generation standard of GB18306-2015 ground motion parameter zonation map of China (hereinafter referred to as "the new zoning map") will be formally implemented starting June 1. Set, near 50% area of Yunnan province to new seismic standards VIII.

Earthquake disaster prevention Department of Yunnan Seismological Bureau Deputy Director Wang Yong said, "the new zoning map has two main changes, one is undefended areas were canceled nationwide, the second is in the Appendix will be ground motion parameter explicitly to the Township. ”

Specific to Yunnan, city fortification levels increased towns above the county level improve the ratio of 22.5%; Basic seismic peak acceleration in the province 0.10G high intensity area and above also increased significantly.

Among them, the basic seismic peak acceleration 0.10G and above (equivalent to intensity VII and above) the area increased from 87% to 91.12%;0.20G (VIII) and above the area rose from 36% to 44.67%.

Wang Yong said, "This means set by the new zoning in Yunnan province, new buildings earthquake-resistant level of review to further improve, near 50% area new homes are earthquake-resistant standards be raised to VIII, more than 90% region to VII. ”

"Yunnan is China's earthquake-prone regions, with high frequency and magnitude, characteristics of the widespread and serious. The seismic capacity of rural buildings is low, constraints and problems of regional economic and social development. "Wang Yong said that Yunnan has about 15 million people living in active fault-controlled basin, potential threat is huge. Improve the ability for earthquake fortification of the construction project of Yunnan province, is particularly important.

Yunnan province earthquake Council earthquake victims defense at engineers Wen Wen said, for this a situation, Yunnan province earthquake Council will active led all sector, further do new, and alterations, and expansion construction engineering of seismic fortification work, while through rural dangerous old housing transformation and seismic housing engineering, and earthquake Hou recovery reconstruction, and created earthquake security model community, engineering, strictly implementation latest to vibration parameter Division figure, effective strengthening Yunnan rural houses seismic capacity, ensure people of life property security.

新地震区划图6月起实施 云南新建房抗震标准提高

　　中新社昆明5月12日电 (记者 胡远航)记者12日从云南省地震局召开的“防震减灾”新闻发布会上获悉，新修订的第五代国家标准GB18306-2015《中国地震动参数区划图》(简称“新区划图”)将于6月1日起正式实施。按设定，云南近五成地区新建房屋抗震标准提至VIII度。

　　云南省地震局震害防御处副处长王勇介绍称，“新区划图有两大主要变化，一是全国范围取消了不设防地区，二是在附录中将地震动参数明确到乡镇。”

　　具体到云南，城市抗震设防水平普遍提高，县级以上城镇提高比例达22.5%；全省基本地震动峰值加速度0.10g及以上的高烈度区域面积也明显增加。

　　其中，基本地震动峰值加速度0.10g及以上(即相当于地震烈度VII度及以上)的区域面积由87%上升到91.12%；0.20g(即VIII度)及以上的区域面积从36%上升至44.67%。

　　王勇表示，“这也就意味着按新区划图的设定，云南省新建审查的房屋建筑抗震级别进一步提高，近五成区域的新建房抗震标准提至VIII度，九成多的区域提至VII度。”

　　“云南是我国地震多发省区，具有频度高、震级大、分布广、灾情重的特点。广大农村民居抗震能力低下，成为区域经济社会发展的制约和隐患。”王勇指出，云南约有1500万人居住在活动断裂控制的盆地，潜在威胁巨大。提高建设工程的防震设防能力，对云南省尤为重要。

　　云南省地震局震害防御处工程师文雯表示，针对这一情况，云南省地震局将积极牵头各个部门，进一步做好新建、改建、扩建建设工程的抗震设防工作，同时通过农村危旧房屋改造和抗震安居工程、震后恢复重建、创建地震安全示范社区等工程，严格执行最新地震动参数区划图，切实加强云南农村民居抗震能力，确保民众的生命财产安全。
