The earthquake made Taiwan move! Large earthquakes will cause significant surface displacements. The Central Weather Bureau posted a comparison chart of “Taiwan’s 9-year movement” two years ago. It caused a wave of discussion at the time. The recent frequent occurrence of earthquakes has attracted attention again. The Meteorological Administration mentioned that in addition to “coseismic slip” that occurs in just tens of seconds during earthquakes, faults also secretly move before earthquakes (interseismic periods) and after earthquakes (post-seismic periods). .
Netizens joked that “we are getting further and further away from China.” Villagers: The Ice Age is connected again
By monitoring ground deformation, geoscientists can monitor faults, volcanic activity, and subsidence or sliding, the agency said. From a surface perspective, large earthquakes can cause significant surface displacements. For example, the displacement of the Chelungpu Fault has caused a violent, 105-kilometer-long scar on Taiwan’s surface. The horizontal displacement of the hanging wall of the fault ranges from 1 meter to Ranging from 9 meters.
Earthquakes are the result of a compressed plate releasing energy and causing displacement in a short period of time as stress accumulates. The Meteorological Administration mentioned that the earth’s crust not only moves during earthquakes, but also in the process of “accumulating energy” in the earth’s crust, very small deformations or inconspicuous earthquakes will occur on the surface. Earth scientists use this principle to continuously monitor every move on Taiwan’s surface over a long period of time, hoping to find signs before a major earthquake occurs.
According to the map released by the Meteorological Administration, it can be seen that Taiwan is indeed moving eastward, and many netizens also joked that it is “getting farther and farther away from China.” However, the Meteorological Administration mentioned that Taiwan is indeed moving eastward, but it must also observe changes in China. “Whether Taiwan is moving away from China” must be compared based on the movement of the Chinese plate. Many netizens also responded, “This is an interesting fact”, “If we enter the ice age, we will be connected to China again”, “Can this movement keep up with the siltation speed of the western outlet?”
The Ministry of the Interior teaches disaster prevention tips: “Don’t look up.”
According to statistics, starting from 5 pm on the 22nd, there were 237 earthquakes in 19 hours. In response to earthquake preparedness, the Ministry of the Interior recently posted on Facebook that when the earthquake occurred, many people said, “Go open the door first and then hide quickly.” However, this statement is actually wrong. The most important thing is not to escape, nor to rush to open the door first, but to lie down, cover, and hold on. Any rash movement will put you at risk of injury.
The Fire Department of the Interior Ministry also wrote on the “Fire Disaster Prevention Center” website that if you are taking shelter indoors, if there is a shelter nearby, please hide directly in it. For example, under the table, etc. If there is a wall nearby, you can also move towards the corner and lie down to protect your head and neck. But please pay attention to whether there are potentially dangerous falling objects on the wall.
In addition, do not look up to avoid being injured by falling lamps, fans or ceiling objects. Because the fluorescent lamp may be broken, if you look up at this time, you may be easily stabbed by the fragments. Only try crawling during an earthquake if it is really unsafe to do so above your head. After climbing away from the high-risk area, immediately stop and take cover until the earthquake stops.
