Another place, a 7.3 magnitude earthquake occurred! Has the earth entered "vibration mode"?

The China Earthquake Networks Center officially determined that a magnitude 7.3 earthquake occurred at 20:18 on March 30 in the Tonga Islands (20.30 degrees south latitude, 173.75 degrees west longitude), with a focal depth of 10 kilometers.

The Tsunami Warning Center of the Ministry of Natural Resources has determined based on preliminary earthquake parameters that the earthquake may trigger a local tsunami around the epicenter, but will not affect China's coast . Currently, the US Tsunami Warning Center has lifted the Tonga tsunami alert .

Also last night and this morning, news of earthquakes in Guangdong, Xinjiang, Tibet and other places in China became a hot search. According to the official measurement of the China Earthquake Networks Center:

At 20:24 on March 30, a magnitude 3.7 earthquake occurred in Kuqa City, Aksu Prefecture, Xinjiang. The focal depth was 10 kilometers and the epicenter was located at 41.33 degrees north latitude and 83.76 degrees east longitude.

At 20:46 on March 30, a magnitude 3.0 earthquake occurred in Gaozhou City, Maoming, Guangdong. The focal depth was 10 kilometers and the epicenter was located at 22.13 degrees north latitude and 110.98 degrees east longitude.

At 05:44 on March 31, a magnitude 3.8 earthquake occurred in Dangxiong County, Lhasa City, Tibet , with a focal depth of 30 kilometers.

In addition, Myanmar was recently hit by a 7.9-magnitude earthquake, a natural disaster that caused heavy casualties and property losses, which once again triggered discussions about the active period of seismic activity.

Is the Earth in "vibration mode"?

Experts: Earthquake activity period needs scientific definition

Wang Tun, director of the Natural Disaster Early Warning Research Center of Sichuan University and director of the Chengdu Center for Earthquake Early Warning Technology Research of the China Earthquake Administration, said that scientifically defining the earthquake activity period requires retrospective analysis based on long-term and large-scale observation data, such as assessing whether the annual frequency of earthquake activity in a specific area deviates significantly from the historical baseline. Judging that "the earth has entered a vibration mode" based on only a few earthquake activities does not conform to the objective laws of earthquake activity and lacks empirical support.

He specifically analyzed that the Tonga Islands are located in the tectonically active area of ​​the Pacific Rim seismic belt, where several earthquakes of magnitude 5 or above occur every year, making it an area with a high incidence of and active earthquakes.

Xinjiang, Yunnan, Hebei, Guangdong and other areas are located in my country's major seismic belts and tectonic activity areas. According to the analysis of regional seismic activity characteristics, the frequency and intensity of magnitude 3 earthquakes are in line with the normal energy release law under the geological tectonic background.

How to better respond to earthquakes?

When faced with a sudden earthquake, people are in different environments and face different potential risks. Mastering more earthquake prevention and risk avoidance knowledge can effectively increase the possibility of survival.

How and where to hide when an earthquake comes ?

Step 1 : Where to run?

Evacuate immediately and run to an open area. If you are on a high floor, find sturdy furniture or walls for cover to reduce the risk of being hit by falling objects.

Step 2 : Hold on tight

After finding a relatively safe shelter, be sure to hold on to a solid or fixed object to avoid secondary injuries caused by movement.

Step 3 : Take good protection

When dodging, use books, backpacks, pillows, cushions and other coverings to protect important parts such as the head and back of the neck to reduce the chance of injury.

In the process of avoiding, you also need to avoid the following misunderstandings and remember a few "no's" :

①Don’t hide in the elevator ;

② Do not hide under hanging objects such as chandeliers and electric fans ;

③ Do not hide near large wardrobes or other cabinets.

④Do not get close to stoves, gas pipelines and household appliances ;

⑤Do not get close to windows, glass curtain walls and building exterior walls ;

⑥ Do not hide under trees or electric poles ;

7. Do not hide under cliffs ;

⑧ Do not hide on or under bridges ;

9. Do not rush to the streets or roads to escape ;

⑩Don’t hide in the car.
