Fuzhou shock and disaster reduction center answered "three consecutive questions of earthquakes"

On the 17th and 18th, Taiwan issued many earthquakes, up to 6.9, and the earthquake such as Fuzhou was obvious. Many citizens are puzzled: Is it a lot of influence on Fuzhou? Do you want to run? To this end, the reporter interviewed the Fuzhou Earthquake and Disaster Subject Center.

Question 1: Why are there more earthquakes in Taiwan?

According to the China Earthquake Network, at 14:44 on September 18, a magnitude 6.9 earthquake occurred in Hualien County, Taiwan, with a depth of 10 kilometers. "Fuzhou's sense of earthquake is strong", "You can feel it on the first floor", "The first feeling of the earthquake is so obvious" ... For this earthquake, many citizens said that "a strong sense of earthquake".

It is understood that the Taiwan Island is located at the junction of the Eurasian plate and the Pacific sector. It is one of the strongest areas of the Western Pacific earthquake zone. Since 1970, an average of about 13 earthquakes occur at more than 5 times a year, that is, an average of once a month; the average annual magnitude 6 earthquake is 2.1 times, that is, the average magnitude 6 earthquake occurs twice a year.

Among them, the eastern faults of Taiwan have strong activity, and the earthquake activities are more frequent than the western region. More than 200 magnitude 6 to 6.9 earthquakes have occurred, magnitude 7 to 7.9 earthquakes, and two earthquakes above 8 or more. Because the earthquake in the eastern earthquake in Taiwan is far away from Fujian, the occurrence of earthquakes is mainly impact on the coastal area of ​​Fuzhou and Xiamen in Fujian, and has a small impact on Fujian inland inland.

Question 2: How much does it affect Fuzhou?

It is understood that the Taiwan earthquake has little impact on Fuzhou, and citizens do not need to panic.

It is reported that the degree of destruction of the earthquake is measured by intensity. Generally speaking, the larger the earthquake level, the greater the intensity; the farther the earthquake is, the smaller the intensity. my country's earthquake intensity is divided into 12 levels: at 1 degree, human beings are basically indifferent, and only instruments can be recorded; at 2 degrees, 3 degrees, and 4 degrees, most people in the room and outdoor can feel the sense of shock, accompanied by suspension, and suspension of suspension. Swing up; starting from 5 degrees, most people outdoors have a sense of people, and cracks appear on the wall surface. Usually, the earthquake from 1 degree to 4 degrees has little impact on people.

The release terminal of the early warning information of the Fujian Provincial Earthquake Administration shows that the local intensity (Fuzhou) of the Hualien earthquake in Taiwan is 3 degrees, that is, a few people indoors have a sense of static. swing.

Question 3: What should I do if I encounter an earthquake?

At present, the province divides the earthquake early warning into alertly warning (predicting the earthquake intensity of 3 to 5 degrees) and a catastrophic warning (predicting the earthquake intensity greater than equal to 6 degrees).

When receiving earthquake early warning information, citizens must first calm down and take corresponding measures according to the earthquake intensity of the early warning information and their own environment. When the earthquake intensity is less than 6 degrees, pay attention to the danger of falling at the high place without having to make more reactions. When the earthquake intensity is equal to or greater than 6 degrees, the corresponding risk aversion should be taken quickly: the early warning time is sufficient to evacuate the building, and it should be quickly left and run to the open space; A good place to avoid it, and the exempration is evacuated in an orderly manner after the strong earthquake.

Main points of shock absorption: quickly turn off the power and gas; choose the safety place to avoid locally; stay away from the balcony, prohibit the building jump, and prohibit elevators; the safety channel should be taken when the high -rise building is evacuated;

School earthquake avoidance points: choose a safety place to avoid locally, such as under the desk, next to the podium; do not run around, do not close the window; after the earthquake, students are evacuated in an orderly manner under the command of the teacher; , Broaden earthquake avoidance; when the playground or outdoor, can squat at the original land and protect the head with both hands.

Key points for shock avoidance in public places: The audience can squat next to the seat or at the foot of the stage; orderly evacuate under the command of the staff; avoid glass doors, windows, windows and counters, etc., choose a safety place to avoid; The driver should choose a safe place to park in time. Passengers should seize the handrail and reduce the center of gravity to avoid injuries.

The Fuzhou Earthquake Earthquake Disaster Subproduction Center reminds: In order to avoid trustworthy earthquake rumors and error information, citizens can inquire about relevant channels such as the China Earthquake Network website, the Fujian earthquake information service, and the public account of Fuzhou earthquake information service public account. In addition, citizens can download the "Fujian Earthquake Early Warning" APP to receive and inquire about early warning information. (Reporter Zheng Ruiyang)
