Yesterday 17, Ms. Li, who lives in a community in the western suburbs of Zhengzhou, was cooking in the kitchen. She took a bowl of water and put it on the stove, ready to use it with flour. Suddenly, she found the water in the bowl shaking. The water was shaken out because it was a little full. Ms. Li said that she felt a little sick and the floor was shaking. I suddenly realized that it was an earthquake. "The shaking lasted seven or eight seconds." Ms. Li said that when she called her friend, her friend didn't feel anything on the road.
Ms. Wang, who works in an office building near Zijingshan, obviously felt the vibration. There are several metal filing cabinets in her office, each with a movable handle. At that time, she was sitting on the opposite stool when she suddenly saw the handle of the cabinet shaking back and forth, and the handle would make a noise when it touched the iron sheet. "Did you feel the ground shaking just now?" Ms. Wang asked her colleagues around her, and most of them felt the same way.
A netizen said that he lives in a community in huanghe road. At that time, she felt the vibration and rushed down from the seventh floor.
The vibration is not only felt by Zhengzhou citizens. In Baidu's "Earthquake Bar", many netizens posted that they felt an earthquake.
"Jiaozuo has a sense of earthquake and seeks the epicenter." Some netizens posted for the first time.
Then, the netizen of Luohe said, "Everything in the house is shaking and shaking, and the sound is very loud"; Xuchang netizens said that they obviously felt the earthquake; Netizens in Pingdingshan said that the table had been shaken several times, and it was the first time I felt such a big range; Netizens in Shangqiu, Xuchang, Luohe and other places also expressed a sense of shock.
A citizen of Luohe: "I was cleaning the kitchen and suddenly felt dizzy. Then I saw the soy sauce bottle and the vinegar bottle swinging back and forth on the stove. "
Ms. Li of Lisan Garden Community in Luohe City: "I couldn't watch TV at that time. It took about 1 minute for the TV to return to normal. "
A teacher of Luohe Medical College: "The earthquake was so strong that many students ran out of the teaching room and many people gathered in the open space of the square."
Many Luohe passengers on the D 136 EMU: "Half an hour before the earthquake, we were all surprised to find that the sky that was just on suddenly became dark as night, and the time lasted for more than 1 minute."
Mr. Zhang from Yucheng, Shangqiu City: "The lights in my house are flickering, and the house and bed are moving. The sofa on the 0/0 floor of a friend's house/KLOC-has moved a few centimeters. "
Wang Hongbin, deputy mayor of Xuchang City, who went to the Seismological Station of Xuchang City to learn about the situation, said: "After receiving the report from the Seismological Bureau, Xuchang City immediately started the emergency mechanism and all the personnel on duty were in place. The emergency detachment of the Seismological Bureau rushed to Yanling County immediately after the earthquake to understand the situation. "
Judging from the posts posted by netizens, it is mostly netizens in Henan who feel the vibration.
However, many netizens reported that some areas in Shandong, Shanxi, Anhui and other provinces also had obvious earthquakes.
A netizen in Jining, Shandong Province said that he was sitting in front of the computer and felt a flash. He was stunned and immediately thought that it would be an earthquake. He immediately ran to the bathroom, saw that everything was normal outside, and then went back to the computer to search online. People who feel the same way with him are posting. A netizen in Hefei said that her family lives on the 10 floor, and there is also a sense of shock.
In addition to exchanging feelings, netizens really want to know where the earthquake happened. On 24th 16: 58, there was a strong earthquake in Zhumadian City when Zhoukou City was attacked.
After the earthquake, the Henan South Earthquake Rapid Emergency Team (established on June 65438+1October 65438+March 3), which was established less than half a month in our province, rushed to the earthquake site after receiving the instruction from the Provincial Seismological Bureau and put it into earthquake relief.
According to Ma Tao, director of the Seismological Bureau of Zhumadian City, the South Henan Earthquake Rapid Emergency Team consists of professionals from earthquake departments in Zhumadian, Nanyang, Xuchang, Pingdingshan, Zhoukou and Luohe, who rushed to the scene at the first time of the earthquake. Its task is to strive to achieve the "four firsts", that is, the first (professional) to arrive at the scene, the first to spread scientific and accurate information, the first to invest in earthquake relief, and the first to make decision-making suggestions. At about 7 o'clock last night, the reporter rushed to Banqiao, Taikang County, the nearest township to the earthquake center. I saw the streets full of panicked people, and everyone was worried about aftershocks.
The reporter learned that many houses in the town have cracks to varying degrees, but no collapsed houses have been seen. In the home of a resident on the roadside, on the courtyard wall more than 2 meters high, cracks have been extending from the wall head to the wall root. Mr. Zhang, who was in the yard at that time, was talking at the door and was startled by the sudden noise. "At that time, I heard a knock at the door, louder than thunder. I thought whose house collapsed, and later I learned that it was an earthquake. "
In a supermarket at the intersection of Banqiao, the reporter saw that the drinks in the refrigerator were not classified before, and the wall clock was hung obliquely on the wall.
The reporter traveled north along Banqiao to Changying Town. Along the way, the villages on both sides were brightly lit, and no villages with power outages were found. Along the way, police cars patrolled the street.
Zhu Junwei, the mayor of Chang Ying Town, told the reporter that after receiving the notice at 5 pm, the town cadres gathered urgently to start the emergency plan and actively carry out emergency rescue. If there are special circumstances, villages and groups can send people to the scene at any time.
At 9 o'clock in the evening, on Banqiao Street, for fear of aftershocks, some villagers here directly put their beds outside the door, and some used their vans as "bedrooms". Last night, the reporter learned from the Zhoukou City Emergency Office that there were disaster reports in Taikang County and Fugou County.
After the earthquake, 12 students were injured when the students of the first junior middle school in Xunmukou Town, Taikang County were evacuated from the teaching building, and were sent to the county people's hospital for treatment. Among them, 8 students were hospitalized for observation and treatment, and 4 students were seriously injured and are currently being rescued. As of 8 o'clock last night, there were 24 houses collapsed in the earthquake, including Banqiao 10, 6 in Zhimawa Township, 4 in Xunmukou Town, 2 in Wulikou Township and 2 in Wharf Town.
As of 9: 00 last night, in this earthquake, tiles fell off and cracks appeared in 40 houses in Fugou County, and cracks appeared in two bridges. No casualties were reported.
There is no disaster report in Xihua County.
Regarding the disaster situation, the local government is still making further statistics. Yesterday, another reporter of this newspaper followed the emergency team of the Provincial Seismological Bureau to the earthquake zone. At 0 19: 00 that day, an aftershock of magnitude 1.6 occurred again in Banqiao, Taikang County. Lv Guohe, deputy director of the Provincial Seismological Bureau, said that according to the monitoring feedback information, it can be judged that there is little possibility of a bigger earthquake, and people have no problem sleeping in the house at night.
At 23: 30 yesterday, the reporter saw in Fugou that many residents chose to sleep on the streets. After the local government departments kept informing the residents about the earthquake, the residents' mood was stable.
It is understood that the emergency team of the Seismological Bureau of the province has set up 19 temporary earthquake monitoring points around Taikang, Fugou, Xihua and Huaiyang counties to monitor the development of the earthquake at any time. Last night, the reporter connected the China Seismological Network Center. According to Liu Jie, director and researcher of the earthquake prediction department of the center, Zhoukou earthquake was a shallow earthquake with moderate intensity. This kind of earthquake is just a feeling and won't cause much damage.
The earthquake occurred near the Xuchang-Taikang fault zone. The epicentral distance of this earthquake is 100km, and there are 8 earthquakes of magnitude 5 or above in history, including 2 earthquakes of magnitude 6. The largest earthquakes occurred in Xuchang, Henan Province on February 1524 and August 4 1820 respectively, and the latest earthquake with magnitude above 5 was Tongxu1965438+August 9, 2008.
Since 1970, there have been no earthquakes of magnitude 4 or above within the epicenter 100km, but there have been many earthquakes of magnitude 3.
This area is a region with low seismic activity in China, and the level of seismic activity is weak. Judging from the seismic activity, the Zhoukou M 4.7 earthquake occurred in an area with a low level of seismic activity. In history, most moderate and strong earthquakes in this area were single, and it is unlikely that earthquakes of magnitude 5 or above will occur again in the near future.
Although this earthquake has little impact on our province, what should we do about our earthquake resistance in case of a major earthquake?
Liu Yaoxing, deputy director of the Provincial Seismological Bureau, said that after the earthquake, everyone would be concerned about whether their houses were earthquake-resistant and how strong the earthquake could be. At present, different regions in our province have different requirements for seismic capacity of buildings. "For example, the seismic fortification intensity of Zhengzhou is 7 degrees, which means that Zhengzhou can generally resist earthquakes of magnitude 5.5, while Anyang and Xinxiang can generally resist earthquakes of magnitude 6 or so. Urban buildings are ok, but the seismic capacity of rural buildings is weak. " Liu Yaoxing said that cities are far better than rural areas in terms of earthquake resistance. Yesterday afternoon, Ms. Wu, who worked in Zhengzhou, received a phone call from her relatives in Taikang, her hometown, saying that there was a local saying that the earthquake would last for four days in a row, and many people were afraid to go home for this reason.
Last night, the Business Daily reporter specially interviewed experts from the Provincial Seismological Bureau.
Wang Zhimin, director of the mission center of the Seismological Bureau, who has been studying crustal deformation for a long time, said in an interview that there may be aftershocks after the earthquake, but it is a rumor that it lasts for four days. Please don't believe it.
"Earthquake rumors generally have three characteristics: first, gossip, not published by authoritative departments; The second is that they are all superstitious; Third, the more accurate the forecast, the lower the credibility, especially when it is accurate to a certain day, a certain time and a certain level. " Wang Zhimin said.
