Two earthquakes
In less than two minutes, There were two major earthquakes of magnitude 6.0 and magnitude 7.4 in succession in Fukushima, Japan, according to relevant statistics, several deaths have been caused, 2 million households have lost power, and in response to the problem of nuclear power plants that everyone is concerned about, the current official answer is that everything is normal, so will this earthquake be a harbinger before the arrival of the earthquake, or will there be a stronger earthquake in the future?
Earthquake volcano country
Japan sits on top of a plate and is a veritable earthquake volcanic country. Both the number of earthquakes in Japan and the number of volcanic eruptions are among the highest in the world, and the frequency of earthquakes in Japan is also extremely high. After all, because it sits on top of the plate, because the continental plate is in constant motion, a little friction or energy release is enough to form a big earthquake.
Aftershocks of 311
According to Japanese scientists, the earthquake is most likely to be the aftershock after the 3.11 Japan earthquake, and it is not ruled out that there will be a larger and stronger earthquake in the future, and I hope that everyone can take safety precautions in time. Speaking of the 311 Japan Earthquake, everyone knows it. It was a major earthquake that occurred on March 11, 2011, and the scale of this earthquake is recorded in history.
Plate movement
So what is the relationship between the 311 earthquake and this earthquake? We know that earthquakes generally come from the movement between plates, and the squeezing, friction and landslides of plates will carry huge amounts of energy, and this force will continue to break through the barrier of the earth's crust, which is the ground stress. When the ground stress on the local crust reaches its limit, the crust will be completely torn apart by the huge energy underground.
The huge energy brought by the underground spews out from the torn crust, and the consequences will bring huge losses to the safety of human life and property. This is our most common shallow source earthquake, of course, there are some earthquakes, occur in the underground tens of kilometers, or even hundreds of kilometers underground, this is the deep source earthquake, deep source earthquake generally acts on the ground, and because the energy propagation is from the bottom up, these energies are constantly weakened, and finally until stopped, which is why when a deep source earthquake occurs, we do not feel anything at all on the ground.
311 Japan Earthquake
The magnitude 9 earthquake caused by March 11, 2011, was a shallow source earthquake. One set of data shows that the earthquake killed a total of 15,000 people and released as much energy as the entire United States used for as much as a month. The earthquake, in the center of the epicenter, directly caused a tsunami of up to 930 centimeters, and the Ocean Tsunami caused by the earthquake could also be felt in the United States on the other side of the ocean.
According to NASA, the 311 earthquake severely damaged the geological structure of the stratigraphy, which moved the entire Japanese island of Honshu to the east by about 3.6 meters and accelerated the rotation of the earth by 1.6 microseconds.
This article summarizes
Japanese scientists: Compared with the relevant data and geographical location of the 311 earthquake, the location of the 311 earthquake and the Fukushima earthquake is almost not much deviation, so it is inferred that the earthquake is the aftershock after the 311 earthquake, that is to say, the impact of the 311 nine-magnitude earthquake is still continuing, and we do not rule out that there may be stronger earthquakes in the future.
