On march 29, beijing, xinhua news: the earthquake is on the rise. How can you save yourself after the earthquake? Expert detailed
Xinhua news reporter round
On 28 march, an earthquake of 7. 9 magnitude struck myanmar, causing significant loss of life, injuries and property damage. Why was the earthquake devastating, did the earth enter its active phase, and what were the errors in saving itself after the earthquake? In response, experts in the field of emergency management provided detailed information。
Why is this earthquake devastating
An expert analysis of the china earthquake network centre concluded that the earthquake was in the arc region of myanmar. Since the beginning of the new generation, there have been violent collisions between the indian and euro-asian plates, leading to a large reduction in the rock collage and the formation of the himalayan mountain belt. The myanmar arc region, located in the eastern tectonic ring of the himalayan mountain belt, with a strong tectonic deformation of the earth's crust and a strong seismic activity, forms a series of north-south tectonic units and faults and is one of the most active areas of the himalayan earthquake belt。
Statistics show that since 1900, more than 10 earthquakes of 7 magnitudes have occurred within a 300-kilometre radius of the epicentre of the earthquake, the largest being the 8. 0 magnitude earthquake in myanmar on 23 may 1912。
This earthquake is known to be the largest earthquake in the world since this year。
“the earthquake was a typical shallow-source earthquake within the earth's crust, and its fractured face could enter and exit the surface of the ground, causing it to vibrate strongly.” according to the institute of geophysical research of the china earthquake bureau, this fracture zone is close to myanmar's more densely populated area, causing a large number of housing buildings to collapse and putting the emergency response to a more severe test。
Is the earth entering seismic activity? What's the difference in seismic data
Has the recent occurrence of 17 magnitude 6 and above earthquakes around the globe since this year meant that the earth has entered a period of active vibration
“global seismic activity has been generally lower since this year than in previous years. It is hard to say that the earth is in an earthquake-active phase after the earthquake, as it is now。
In response to the same earthquake, china's seismological network usually publishes “autometric” and “official” messages, which differ slightly between the time, location and magnitude of the earthquake
The experts explained that the first “automatic determination” was a quick calculation of the reference “three elements”, i. E. Seismic timing, epicentre and magnitude, by which computers read and analyse data monitored by seismic instruments. The second “official determination” is the “accurate answer” ultimately produced by scientists through a series of operations, such as manual computing, so there is a slight difference between the two messages。
In addition, the level of shock given by different agencies sometimes varies during the same earthquake. According to industry sources, there are a number of influencing factors behind this, mainly because of the different seismic scales used, such as the wave level, the body level, the rectangular level, etc., “the different seismic scales, which are much different than the ruler, and the magnitude of which is different”
How do you save yourself after the earthquake
“earthquakes have the characteristics of instantaneous occurrence, destructiveness and the severity of secondary disasters. Mapo, director of the emergency management institute of the central party school of the chinese communist party (national administrative institute), is a reminder of the principle of safe haven in the immediate aftermath of the earthquake。
In the room, a quick determination of the location and vibrating condition of the person is made, he/she is taken in close proximity to a small open house such as a bathroom, where the water is not close to the fire and the neck is protected; he/she does not stand by the window or the balcony in order to be injured by falling objects, if he/she is in the classroom or the library, far from the bookshelve, under the desk, with his/her hands holding his/her legs; he/she is not allowed to leave the room until he/she has stopped shaking and has confirmed his/her safety in the outdoors; he/she does not leave the elevator, jumps from the floor or breaks the window; he/she chooses to walk down the stairs。
Outside, get to the open area as soon as possible; stay away from high buildings, avoid buildings such as buildings, glass curtain walls, cross-bridges, street bridges, high chimneys and billboards, or large objects that are prone to collapse; stay away from dams, steep cliffs and plants or facilities that are flammable and explosive, and that contain dangerous chemicals。
Mabel was introduced and, in order to remain calm and to preserve his physical strength, a distress signal could be sent out, such as a stone knock. Increased exercises at regular intervals to improve disaster prevention and mitigation by learning more about earthquake avoidance。
In addition, experts have reminded a number of earthquake escapes of areas of error that need to be noticed。
Zone one: after the earthquake, you ran out of the house
If indoor seismic conditions and construction quality are good, preference should be given to indoor seismic protection. Earthquakes occur at a moment when people are more likely to be hit when entering or leaving a building; bricks on the roof, billboards, glass walls, etc. Are also at risk of collapse; and people living in the upper echelons are prone to confusion and unnecessary trouble if they are to flee at the same time。
Wrong area two: hide in furniture like closets
While the closet is strong, it is too high and easily tilted, and when people reach it, their vision is hampered and their limbs are bound, not only by missed escape opportunities, but also to the detriment of rescue。
Zone three: stay on the ground or wait for rescue
The position of lying or lying down at the time of the earthquake is dangerous, which increases the area of the body, is more likely to be hit by objects such as debris than when standing, and is not conducive to physical flexibility. The best position is to guard the head with both hands and bending back。
