An earthquake struck Taiwan
According to data from the China Earthquake Observatory Network, since the early morning of March 23, taiwan has experienced as many as 8 earthquakes in succession, from 1 a.m. to 5 a.m., of which 8 earthquakes have been recorded, 7 are in the sea, 1 is on land, the maximum magnitude is 6.6, the minimum magnitude is 4.1. So what is the cause of this earthquake, and will there be a stronger earthquake in the future?
Here are the specific data released by the National Seismic Observatory:
At 1:06 a.m., a 4.5-magnitude earthquake occurred in the waters of Pingtung County, Taiwan, with a focal depth of 19 kilometers.
At 1:41 a.m., a magnitude 6.6 earthquake occurred in the waters of Taitung County, Taiwan, with a focal depth of 20 kilometers.
At 1:43 a.m., a magnitude 5.7 earthquake occurred in Hualien County (land) in Taiwan, with a focal depth of 20 kilometers.
At 2:11 a.m., a magnitude 4.1 earthquake occurred in the waters of Taitung County, Taiwan, with a focal depth of 20 kilometers.
At 2:37 a.m., a magnitude 4.7 earthquake occurred in the waters of Taitung County, Taiwan, with a focal depth of 30 kilometers.
At 3:35 a.m., a magnitude 5.2 earthquake occurred in the waters of Hualien County, Taiwan, with a focal depth of 15 kilometers.
At 4:29 a.m., a magnitude 5.7 earthquake occurred in the waters of Taitung County, Taiwan, with a focal depth of 20 kilometers.
At 5:41 a.m., a magnitude 4.3 earthquake occurred in the waters of Taitung County, Taiwan, with a focal depth of 15 kilometers.
Pacific Rim Seismic Belt
Why do earthquakes occur frequently in Taiwan? The answer is that Taiwan is located in the geographical location of the Pacific Ring Earthquake Belt, the Pacific Ring Seismic Belt is a huge seismic belt, distributed in a ring around the Pacific Ocean, according to statistics, the total number of earthquakes in the world every year, of which nearly 80% originate from this seismic belt, so it is also known as the most active geological formation area in the world.
In fact, most earthquakes come from the huge energy released from the earth's interior, and the strength of these energy releases is different, which determines the level of the earthquake. The Pacific Rim seismic belt in which Taiwan is located is one of the most active regions on Earth, and it is this feature that also contributes to the complex terrain here, where almost all islands, trenches and volcanoes are distributed.
Water ice action
As we all know, the earthquake originated from the movement of the plate, and Taiwan is located at the junction of the Eurasian plate and the Pacific plate, so the geological structure here is extremely unstable. According to scientists, 4.5 billion years ago, the Earth was not yet formed or was in its early stages.
At that time, the mass of the Earth was not as large as today's Moon, and in this process, the Earth absorbed a large number of water ice objects contained in space, which directly broke into the mantle and then gradually cooled down on the Earth.
Under the action of pressure, these water ices begin to move along the mantle articulation layer to the surface, and finally gather somewhere, and after reaching a certain level, they will erupt and release huge amounts of energy. Of course, this is only one of them, and there may be many reasons for the occurrence of earthquakes.
Geocentric energy release
However, the simplest and crudeest statement is the release of the core energy inside the earth, because the earth's interior contains extremely strong high temperature and high pressure, in some cases, these huge energies will penetrate to the surface, when the huge energy, more than the pressure on the crust where the plate is located, the crust will rupture, and the huge energy will erupt from the ground to form an earthquake.
Serious threats
Earthquakes are also divided into many kinds, our most common is the tectonic earthquake, tectonic earthquake is the earthquake that occurs in plate movement, which is also a type of earthquake that occupies the largest variety of earthquakes in the world, tectonic earthquakes usually bring great damage to human property, because most of the tectonic earthquakes are shallow source earthquakes, which produce huge amounts of energy, which can directly spread to the surface, causing the house to collapse The terrible natural disaster of road traffic facilities being destroyed.
This article summarizes
Whether this earthquake is related to the Fukushima earthquake on March 16 is more likely to be precise. After all, the two earthquake locations belong to the Pacific Rim seismic belt, and the cause of the Fukushima earthquake in Japan is considered by Japanese experts to be the aftershock of the 311 earthquake, so it can be inferred that this earthquake may also be related to the 311 earthquake.
After all, the 311 earthquake in Japan reached a terrible magnitude of 9, and this strong earthquake moved the Japanese island of Honshu to the east by about 3.6 meters, speeding up the rotation of the earth by 1.6 microseconds. The geological formations of the region have been severely damaged, and this effect may continue for a long time to come.
