The earth is like a boiling cauldron with earthquakes over 4 on the Richter scale, only in Sofia it was weaker with the epicenter in the capital
This August, the Earth is different – it is raging like a boiling cauldron, and these days some of the large seismic foci have activated in an indescribable way. 10 earthquakes in 24 hours hit Halkidiki, beloved by hundreds of thousands of Bulgarians, and caused serious concern. Romania has experienced several earthquakes since the beginning of August, the latest of which was on August 11, while Japan and Sakhalin registered a nightmarish 7.1 and 6.5 on the Richter scale. The big surprise in this case was presented to us by the scientists in Tokyo, who proved that they are getting closer to successfully predicting mega-earthquakes.
On August 12, there were even in Sofia, and the epicenter in the capital revived fears of the dangerous Boyan fault. Along with this, there were several above the fourth degree on the island of Crete, in Syria, Turkey and Los Angeles.
In Halkidiki, the strongest tremor reached magnitude 4.5, which is slightly above normal levels. “The region itself has a low seismicity between 2.3 and 3.8, while now it has slightly exceeded this range,” Assoc. Plamena Raykova from the Department of Seismology and Seismic Engineering of the National Institute of Geophysics explained to “24 chasa – 168 istori” , geodesy and geography at the BAS. According to her, Greece is known for its seismicity, but especially for Halkidiki it is moderate to weak.
“There, in general, the earthquakes are mostly shallow – up to 50 km – the seismologist also pointed out. “The further south you go towards Crete, the outbreaks become deeper and the earthquakes stronger.”
Almost at the same time, on August 11, 240 km from Vidin and 390 km from Sofia, in neighboring Romania, our neighbors encountered a magnitude 4.7 on the Richter scale. Only 6 days after another earthquake in Vrancha from the fourth.
On August 8, Japan was hit with a force exceeding 7 on the Richter scale and a day later, on August 9, after analyzing the situation, seismologists in the country warned that the population should prepare for a mega-earthquake. They indicated that they could not commit to a date, but there would be one.
“The probability of a new one is higher than usual,” the scientists in Tokyo predicted. Of course, a colossal emptying of stores began immediately afterward. The government had to urge people not to stock up on products for more than a week. And while across the country was preparing for something colossal, a day later, on August 10, the forecast came true. The seismological station in Sakhalin, north of Japan, registered an earthquake with a magnitude of 6.5 in the southern part of the Sea of Okhotsk – in the area between the Land of the Rising Sun and Kamchatka.The epicenter was about 151 kilometers from the city of Dolinsk in Russia.
In fact, this prediction deserves congratulations and is truly sensational, because it was the first time that science was able to predict with approximate accuracy a whole day before a dangerous earthquake. Naturally, this has its own explanation.
The hypocenter was too deep in the Earth’s bowels – 400 and 410 kilometers away – and the extreme collisions there broke out on the surface as a powerful earthquake.
“This area is characterized by quite deep earthquakes, at the beginning of the year there was another earthquake of 7.1 on the Richter scale, I assume that the very movement of the structures “told” the seismologists that there would be another one, although they did not commit with a deadline – explained Prof. Raykova – In addition, they most likely made the statement based on a probabilistic scenario. For example, we can also say that in a period of 475 years an earthquake of magnitude 6.5 can occur. in the Sofia area. The scenarios themselves are prepared on the basis of statistical data on earthquakes in the past.” From this point of view, the explanation is that scientists in Japan, knowing their seismicity, relying on statistics and considering the realization of weaker tremors before the main one, have considered it appropriate to announce that there is a danger.
The fact is that the Land of the Rising Sun is located in an area saturated with some of the strongest earthquakes on the planet, and there they are aware that sooner or later a catastrophic earthquake of more than 8 on the Richter scale will always occur. On the other hand, science is getting a clearer “view” of what processes are raging in the bowels of the earth, and perhaps the day will not be far away when tens of thousands of people can be saved from death with accurate predictions.
