Master God once again showed off his power. A 7.8-magnitude earthquake broke out in the waters near the east coast of Kamchatka, with a focal depth of only 20 kilometers. Petropavlovsk-Kamchatsky was about 131 kilometers away from the epicenter, and there were as many as 33 large and medium-sized cities within 300 kilometers, and the number of small and micro cities was even larger.

After the earthquake, the surrounding coastal countries became tense, including several countries including Russia and the United States, which had repeatedly raised tsunami warnings to prevent possible earthquake catastrophes.

The earthquake in the ocean accounted for 80% of all earthquakes worldwide, according to this ratio, it seems that this sea-level 7.8 earthquake is not uncommon, but it is worth noting that the location of the earthquake is near the ocean, the earthquake intensity is high, the depth of the earthquake source is very shallow, and already has the earthquake energy to cause damage to the coast of the nearby sea.

After the strong earthquake ended, the surplus earthquake continued, a dozen consecutive super-4.8 earthquake surplus waves, revealed a signal to the outside world, the energy contained in the strong earthquake is very strong, it has not yet been released, in the future will not trigger a higher level of earthquake, no one can give a conclusion.

The Aryan Islands, Hawaii, and the Russian coast, have all entered a state of alert for the first time, away from the areas especially close to the earthquake, and even evacuated some of the residents, the tsunami warning of this swelling, the sound of alarm, the importance of not losing at all in an imminent war.

For the reason of the great earthquake, scientists quickly gave. The great earthquake earthquake is located at the border of the North American and Pacific plates, the two plates cause pressure when the movement, can also be understood as a strong collision, releasing powerful energy to the outside, which caused the earthquake. According to scientists estimate, the Pacific plate is currently moving at a rate of 3 inches per year in the direction of the North American plate, the frequency of these two large plates are being pressed almost every year, the accumulated energy to a certain extent will explode, the great earthquake comes from.

However, human beings basically live on land, and the threat of marine earthquakes themselves to human beings is relatively not too high. Even this offshore earthquake has a magnitude of 7.8. However, because earthquake shear waves cannot be transmitted in seawater, the earthquake does little harm to cities more than 100 kilometers away.

However, seismic waves can be rapidly transmitted in the sea water, which means that after a seismic eruption on the sea, the sea water begins to become unstable under the influence of the seismic waves, and the amount of strongly moving sea water accumulates to a certain extent, the probability of a tsunami begins to rise.

As a secondary disaster of sea earthquakes, tsunami has great destructive power. Especially the tsunami caused by offshore earthquakes can cause damage to the surrounding coastal areas to reach the level of "destruction". This is also the main reason why coastal countries are nervous and quickly sound tsunami warnings after the outbreak of a major offshore earthquake!

For example, in 1946, a massive tsunami caused by an earthquake caused by the Arifish Islands. The Arifish Islands erupted a magnitude 8.6 earthquake, and the strong earthquake caused the Arifish Islands to fall into the mountains, causing the coastal mountains and ice to collapse massively, and huge amounts of mountains and ice fell into the sea in a short period of time, almost instantly stirring up near sea level, and the tsunami followed.

Because the tsunami disaster has come too quickly, people living near the Arifish Islands have not yet stood in the residual wave of the earthquake, suddenly a strong tsunami, 159 people died in the tsunami, many states of the United States have been affected to different degrees. It is worth mentioning that it is under the serious consequences of the great tsunami, the earthquake tsunami warning system was established, this is the scene of the multi-nation tsunami alert today.

In addition to the Arifiye Islands, Japan also suffered a major earthquake in 2011, now known as the 311 earthquake tsunami.In the northeastern Pacific Ocean of Japan, the magnitude reached 9.0. Due to the high magnitude, shallow focal point and epicenter of the earthquake offshore Japan, it caused great damage to Japan, and the affected area reached a horrible 80,000 square kilometers.

The economic losses caused by this earthquake areWithin the range of 16-25 trillion yen, the specific economic losses cannot be assessed. It is worth mentioning that this is only the direct loss caused by the earthquake and tsunami. If the indirect loss is calculated, I'm afraid it will reach an incalculable figure.

This earthquake tsunami, resulting in Japan's death and disappearance of more than twenty thousand, more than six thousand people injured, affected by this displaced Japan situation countless. As of March this year, there are still 24 thousand people in the "state of refuge". and this time node from the time the disaster occurred in that year, has been complete 14 years, this 14 years has been enough for a new generation to grow up, but not enough to compensate for the "trauma" brought by the earthquake tsunami in that year.

In addition, the tsunamis caused by earthquakes such as the Messina earthquake and tsunami in 1908, the Lisbon earthquake and tsunami in 1755, and the Indian Ocean earthquake in 2004 all caused equally heavy losses to different countries in different periods. These tsunamis are like the scars of the past, which both make people sad and alert to future generations. This is the reason why neighboring coastal countries have sounded tsunami warnings after the 7.8-magnitude earthquake. The "lessons" of the past are really painful.

The hazard of the tsunami is so great, but it is not yet the "end point" of the disaster, the most worrying in addition to the tsunami, there are strong volcanic eruptions. Especially in the Aylushin Islands there is a large number of volcanoes, once these volcanoes are "awakened" by the strong wave of the earthquake, the danger caused by the ash of the volcano is absolutely no less than the great tsunami.

And this is not an alarming statement, because it was just over a month ago.The Clyutchev volcano on the Canadian Peninsula has just erupted, and the ashes column of the volcano has hit the sky, reaching a height of 6.5 kilometers.In the waters off the east coast of Kamchatka, the magnitude of the quake is so high that it is very likely to causeKlyuchev volcano andEruption of volcanoes on the Aryan Islands.

Once the three major disasters of earthquake, tsunami and volcanic eruption occur at the same time, the coastal scene can be imagined, which makes the situation unavoidable. Even with the development of science and technology, the energy of nature can't be underestimated. Human beings must unite as one, have less hegemonism and more solidarity and mutual assistance. Only in this way can human beings go further and better!
