People who have not heard the earthquake name may not be available in the world If found, they may have felt it once in life Those who were not fortunate enough to know either of these two people, they might say the name - "Earthquake is the earthquake." There is the benefit of saying this way because many people are not familiar with the word "shivering" but these people can say right now and say, "Chad is the shiver to shiver!" Which we can not even imagine in the ghost!
The first name that is called earthquake is inappropriate In the dictionary Ghatale, English is found in "Earthquake" which literally means "Earthquake" in Bangla! In fact, the name would have been more logical as it happens Maybe when the name was named, "the moonquake" did not even recognize the identity of the Bengali people, who knows what is true! However, we will use logical names here, ie, "earthquake" and "moonquake". However, earthquake will only be used to mean earthquake
What is earthquake?
Very common questions are the earthquake? Those who know a bit of science will say - "Earthquake occurs in the collision of tectonic plate". Actually, this is the case
The earth is divided into 4 parts, including core, lower mantle, upper mantle and crust This crust consists of several floating plates, which are called tectonic plates. And these tectonic plates are almost always clashing for one reason or another, which creates earthquake! The question here is that if there is always a clash, earthquakes are almost always going to happen. But that is not! Actually, that too, but we are not able to know all of it If someone goes to the USGS website with a little trouble, then you will see how many earthquakes every moment! Most of which we can not find
What is moonquake?
Let's go to our main discussion now What is moonquake? For some reason, if Chad was shaking then Moonquake was created. But why is it? The problem arises only because Earthquake and Moonquake are not the same What is responsible for the vibrations in the earth is the tectonic plate, but there is no tectonic plate in Chad!
APSE (Apollo Passive Seismic Experiment) for research on Moonquake, a network with 4 seismometers has been developed. The first seismometer was established in 1970 and ended in 1972 And they researched until 1977 Basically, due to the excessive cost, they could not continue the study
The cause of Moonquake occurring
Chad vibration occurs in 4 ways The first thing to discuss about the thermal moonquake, which is mainly due to the change of temperature However, it is weak but, very frequent occurs Generally, the sun begins after the sun sets and continuing continues till sunset That means, there can be an earthquake for a maximum of 2 weeks
The only thing that is said to be, the Moonquake due to Tidal Stress. We, who know a little science, have come to know the scientific reason of tide-down, in elementary school And that is, due to the attraction by Chad, this tide is reduced Actually, this is exactly the case Because of the attraction of the earth, this stress is basically on the chad That is, this earthquake is created due to the attraction between the earth and the Chad And, because the earthquake is very deep, it is sometimes called Deep Moonquake Basically, the study of the APSE, until 1977, Deep Moonquake has been detected from above 7,000.
Meteoroid effectss are mainly responsible for the third earthquake. That is, this earthquake is created only when things like asteroids, asteroids are thrown into Chad.
And finally, the earthquake that we will talk about, Shallow Moonquake The idea is, the Moonquake is the most powerful of it Whichever, the APSE detects 28 detection from 1972-1977 Some of which were according to the Richter Scale 5.5 Many people will be frustrated at seeing this Richter scale, because we are seeing the Richter Scale 9.5 in the world. (Which happened in Chile on May 22, 1960!) But, the problem is that the intensity of earthquake is not understood by the scale of the Richter only. What was more involved with it, time And, all of the Moonquakes have a lot of time And, the Shallow Moonquake can take approximately 10 minutes to several hours Which is really awful
Moonquake why so much time?
The simple answer to the above question is "water"! Water can basically shape a ground like sponge Therefore, when any energy propagate is made, the water is essentially to weaken the vibration. For this reason, earthquakes can not last long in the earth But, on the other side there is no water in Chad, so the soil is very dry As a result, it can not behave like sponges, but what happens is that much like the Tuning Fork! And because of this Moonquake's stability is much more than the world!
