Xinhua News Agency, Shijiazhuang, July 12 (Reporters Yang Fan, Li Jiwei) At 6:38 on the 12th, a magnitude 5.1 earthquake occurred in Guye District, Tangshan City, Hebei Province, and the Beijing-Tianjin-Hebei region felt strong.

　　This earthquake belongs to the aftershock of Tangshan earthquake in 1976

　　Jiang Haikun, director of the Earthquake Prediction Department of the China Earthquake Networks Center, told the media that the earthquake belongs to the aftershock of the 1976 Tangshan earthquake. After the 1976 earthquake, the old earthquake area has been continuously fluctuating. In the early days, magnitude 5-6 earthquakes occurred frequently; after the 1980s, the activity weakened, but the seismicity in this area was still higher than that in the surrounding area.

　　According to experts, since China is located between the two largest seismic belts in the world-the Pacific Rim Seismic Belt and the Eurasian Seismic Belt, the earthquakes are mainly distributed in five regions: Taiwan Province, Southwest Region, Northwest Region, North China Region, Southeast Coastal Region and 23 Earthquake zone, and Tangshan is located at the intersection of the three earthquake zones, the probability of earthquake is relatively high, and the magnitude of earthquake is also relatively high.

　　The reporter learned from the Hebei Seismological Bureau that since 1900, 29 earthquakes (including aftershocks) of magnitude 5.0 or more have occurred within 100 kilometers of the Guye District of the epicenter. Among them, there were 23 earthquakes of 5.0-5.9 magnitude, 4 earthquakes of 6.0-6.9 magnitude, and 2 earthquakes of 7.0-7.9 magnitude. Among these earthquakes, the largest magnitude is the 7.8 magnitude earthquake in July 1976 (spatial distance is about 57 kilometers), and the closest time and space distance are the 5.0 magnitude earthquake in Luan County, Tangshan City, Hebei Province, October 6, 1995. The spatial distance About 6 kilometers.

　　This earthquake is the largest earthquake in Hebei Province after the Wen'an 5.1 earthquake in Hebei on July 4, 2006, and the largest earthquake in North China in recent years. According to statistics, there have been 24 earthquakes of magnitude 3 and above in Hebei in the past five years, including 18 earthquakes of 3.0-3.9, 5 earthquakes of 4.0-4.9, and 1 earthquake of 5.0-5.9. The largest earthquake is this earthquake.

What is the loss of the earthquake

　　After the magnitude 5.1 earthquake in Guye District, Tangshan City, not only the Tangshan earthquake was obvious, but also in Chengde City, Cangzhou City, Langfang City, Xiong'an New District, Hebei Province, and other counties in Qinhuangdao City and Yi County in Baoding City, Zhangjiakou Chicheng and Yuxian felt a slight earthquake. Tianjin felt a strong quake, and the whole city of Beijing felt it.

　　Fortunately, there were no casualties reported in the earthquake. After the earthquake, the Hebei Provincial Fire Rescue Corps raised the level 2 (7.1) requirements according to the actual earthquake level, and quickly launched the first-level response plan for severe earthquake disasters. The provincial fire rescue team mobilized a total of 4,215 earthquake rescue teams, 13 search and rescue dogs, 236 fire trucks of various types, and carried more than 47,000 pieces (sets) of rescue equipment to prepare for cross-regional reinforcement.

　　The command center of Tangshan Fire Rescue Detachment dispatched personnel and equipment to the epicenter at the first time, and the heavy and light earthquake teams of the detachment quickly assembled. Reporters followed fire rescue personnel when they visited the Weifengshan Village in the Bejiadian Town of Guye District in the epicenter area and learned that after two rounds of arranging, there were no cracks in the local area and no people were trapped. Traffic, communications, water supply, power supply, Gas supply and other conditions are normal, and the people's living order is good.

　　On the same day, a video of "Tangshan Construction Road was cracked by earthquake" was widely distributed on the Internet. The reporter learned from Tangshan Urban Management Bureau that the technical personnel rushed to the site for investigation at the first time. After verification, the road on the site was smooth, without cracks, and normal traffic. , "Pavement uplift, severe cracks after the earthquake" is a rumor. The shadow shown in the video is the trace left by the daily grouting and maintenance of the road, which does not affect the quality and safety of the road.

How to prepare for an earthquake

　　Before the earthquake of magnitude 5.1 on the 12th in Guye District of Tangshan, some online "partners" reported through social media that they had received earthquake warning information through terminals such as TVs and mobile phones. According to the Weibo News of the Chengdu Institute of High-Tech Disaster Reduction, the Continental Earthquake Early Warning System built by the Institute and the Earthquake Disaster Reduction Department successfully alerted the Tangshan 5.1 earthquake, and sent early warning information to users who opened earthquake warning before the earthquake.

　　According to experts, earthquake warning uses the principle that radio waves are faster than seismic waves, and intensive intensity meters are installed in the main earthquake areas to alert the target before the destructive seismic waves arrive, so that the people can avoid dangers in time to reduce casualties. When a sensed earthquake occurs, you should first stay calm, protect yourself, observe the situation carefully, take effective measures, and avoid risks scientifically and efficiently.

　　If you encounter an earthquake in the room, you should choose the root of the load-bearing wall, the corner of the wall, or have water pipes and heating pipes to avoid or squat or sit down to protect your head. If an earthquake is encountered in public places such as theaters and gymnasiums. Be calm and calm, especially when the power is off on the spot, don't shout and scream, let alone squash, and squat down or hide under a row of chairs, avoid pendant lights, electric fans and other hanging objects, use leather bags and other objects Protect your head and wait for the staff to evacuate after the earthquake.

　　If you encounter an earthquake outdoors, you can choose to avoid shock in an open area, lie down or squat down, protect your head, pay attention to observation, and avoid dangerous places. If you encounter an earthquake in a public place, you should calm down and don't panic. First avoid it temporarily and evacuate in an orderly manner. Pay attention to protecting your head during the evacuation process.
