Another earthquake
The earthquake has happened again! What's wrong with Earth? According to the report of China Earthquake Network: At 08:37 on February 23, a 7.2-magnitude earthquake occurred in Tajikistan (37.98 degrees north latitude, 73.29 degrees east longitude), with a focal depth of 10 kilometers, it is obvious that this is another destructive shallow earthquake, and the time of the earthquake should be at the moment before dawn for the local area, so you can imagine the destructiveness it brings.
Big, big, small
In fact, our earth, almost every day earthquakes, but the magnitude is not the same, for earthquakes for our daily life, scientists divide earthquakes into three categories, respectively non-sensory earthquakes, sensible earthquakes and strong earthquakes, non-sensible earthquakes are usually earthquakes below magnitude 3, and sensible earthquakes are earthquakes above magnitude 3, strong earthquakes are about magnitude 6 or more.
How destructive an earthquake is depends on its focal depth, if a magnitude 8 earthquake has a focal depth of 1,000 kilometers underground, then it cannot pose any threat to the ground, because the energy of seismic waves in the time when they spread from the ground to the ground, the energy has long dissipated. But a magnitude 6 earthquake with a focal depth of 10 kilometers, then its destructiveness, can destroy houses and tear roads.
Is there a connection
With our detection technology, more and more developed, our understanding of earthquakes is gradually deepening, it is worth mentioning that so far human beings still can not predict the emergence of earthquakes, some netizens said: Tajikistan of this 7.2 magnitude earthquake, and Turkey earthquake is related? The universe thinks there is.
Since the earthquake in Turkey, the Eurasian plate and the Eurasian seismic zone and the Pacific Rim seismic zone in which we are located have changed a lot, which can be called a coincidence, after all, the two are so far apart. The final result of what we bring is this.
A major earthquake in Turkey has more or less had some impact on the earth's plates, and how long this impact will last, we don't know. In fact, such a chain reaction is easy to occur in nature, such as the global warming problem we are currently facing.
Knock-on effects
Climate rise, glacier melting, sea water rise, although this is only a small part, but can affect the air flow, so that the earth's catastrophic weather more and more, this change is that the cold place is not cold, the hot place is not hot, either always cold, or always hot, this abnormal change, is the chain effect of climate warming.
A large earthquake in Turkey seems to have a similar effect, with fewer earthquakes occurring in the most frequent places and more earthquakes in places where they do not, and the 7.2 magnitude earthquake in Tajikistan followed by several small aftershocks in the region. Whether there will be stronger earthquakes in the future is unknown, because earthquakes are unpredictable.
Unpredictable
Because earthquakes usually occur deep underground, the depth of the Mariana Trench reaches more than 10,000 meters, but the depth of the epicenter of the earthquake, the shallowest place is located in the earth's crust 10 kilometers underground, so we simply cannot detect abnormal activity there in advance.
However, throughout the ages, the mainland has also encountered many earthquakes, so there are some folk proverbs to share with you:
Mules, horses, cattle and sheep do not enter the pen, and rats flee in groups.
The chicken flies up the tree and the pig arches, and the duck does not get off the water dog barking wildly.
The hibernating old snake comes out of the hole early, and the bird's pigeon does not return to the nest.
Rabbits jump and bump with their ears up, and swimming fish jump in panic.
Every household carefully observes, and the abnormality is comprehensively forecasted.
This article summarizes
Although the earth is very terrible, as long as you take preventive measures in advance, you can also save your life to the greatest extent, it can be said that the earthquake we usually fear the most, is the kind of early morning, when human beings are asleep, if the magnitude is small, it's okay. If the magnitude is large, as soon as you open your eyes, you see the house falling, how desperate should you be at that moment? The earthquake in Turkey and the earthquake in the Philippines are part of this situation.
On the road of exploring earthquakes, we still have a long way to go, which echoes Qu Yuan's words: The road is long and long, and I will seek it up and down. So, what do you think of this incident? #塔吉克斯坦7.2 magnitude earthquake Xinjiang was strongly felt #
