Earthquake-prone places in Russia
The territory of Russia, in comparison with other countries located in seismically active regions, is generally characterized by moderate seismicity. But in our country there are places where strong 'shaking, "but because it is extremely dangerous to live.
Kuril Islands and Sakhalin
Kuril Islands and Sakhalin part of the volcanic Fire Belt of the Pacific Ocean. In fact, the Kuril Islands - is the top of volcanoes, rising above the surface of the ocean, and in the formation of Sakhalin volcanoes have played a role. Each day record seismic tremors in the area.
At night, May 28, 1995 in Sakhalin was the largest earthquake in Russia over the past hundred years. Neftegorsk was completely destroyed. Despite the fact that the intensity of aftershocks barely exceeded 7 points under the 12-point scale, large-block collapsed seysmoneustoychivye home. Killed 2040 people, more than 700 were injured. The real tragedy is that in this day in high school was an outlet. Building where prom, collapsed, burying graduates.
As always at the earthquake, rescuers were fixed miraculous rescue cases. For example, one man fell into the basement of the house, where he was able to eat for many days remaining pickles, and survived.
The peninsula is also part of the volcanic belt of the Pacific Ocean. In Kamchatka, the 29 active volcanoes and dozens of "asleep".
Small tremors associated with tectonic processes and volcanic activity are recorded every day. Fortunately, the majority of earthquakes occur in the sea and in a sparsely populated area.
Earthquake of 8, 5 points, which occurred November 4, 1952 in Avacha Gulf, entered the 15 strongest earthquakes of the XX century and has been called "the Great Kamchatka". It caused a tsunami that washed away Severo-Kurilsk and reaching as far as Japan, Alaska, Hawaii and even Chile. After that, the Far East seismic network has been established.
The North Caucasus and the Black Sea coast
For residents of the danger of this region have to "thank" the Arabian plate, which faces the Eurasian. In seismologists area it called difficult: Crimea-Caucasus-Kopetdag zone Iran-Caucasus-Anatolia seismically active regions. There are often an earthquake at 9 points and above. On the Russian side considered dangerous territory of Dagestan, Chechnya, Ingushetia and North Ossetia.
The biggest event is called nine-point earthquake in Chechnya in 1976 and Chhaltinskoe earthquake in 1963. All who are born in the USSR, remember the Armenian Spitak, in which 25,000 people died.
Restless, and in the Stavropol region. Tremors felt in the cities of Anapa, Novorossiysk and Sochi. Large 1927 Crimean earthquakes described in the famous novel "The Twelve Chairs".
Lake Baikal is located in the middle of a huge rift zone - breaking the crust. During the year there were recorded up to 5-6 thousand aftershocks. On the rift line, leaving Mongolia, has its own "Valley of dormant volcanoes" on the Oka plateau in Buryatia.
The most famous earthquake on Lake Baikal - Tsagan occurred January 12, 1863. Then, on the southeastern shore of Lake Baikal under water I left the whole valley was formed Gulf failure. The last strong earthquake occurred August 27, 2008. The epicenter was located in the southern waters of Lake Baikal, the power was 10 points. In Irkutsk felt 6-7. People panicked, ran out into the street, collapsed cellular communications. In Baykalsk where felt to 9 points, work was interrupted pulp and paper mill. Fortunately, the majority of large earthquakes in this region does not result in casualties, as the area is populated by small and multi-storey building is designed for the tremors.
Altai and Tuva
And in the Altai and Tuva to earthquakes result in complex processes. On the one hand, a region affected by a huge slab of Hindustan, due to which the movement in the north and formed the Himalayas, on the other - the Baikal Rift. Seismic activity is increasing in the region.
In the Altai, a lot of noise caused a 10-magnitude earthquake, which took place September 27, 2003. It has come to Novosibirsk, Krasnoyarsk and Kuznetsk Basin. Hit six districts of the country, it was destroyed Beltir village, 110 families were left homeless. We received the destruction of the building in the villages of Kosh-Agach and Aktaş.
In Tuva, the local population frightened earthquake occurred the evening of December 27, 2011. The settlements of the republic cracked and crumbling houses. Chandeliers swayed in the homes of the residents of Abakan and Novokuznetsk. Fear has added that the street was the dead of winter. Seismic activity continued for almost the entire winter. So, in February 2012. Seismologists counted more than 700 aftershocks.
In the vast area of Yakutia there are two seismic belts. North comes from the Lena Delta in the Sea of Okhotsk along the ridge Cherskogo, south - Baikal-Stanovoy stretches from Lake Baikal to the Sea of Okhotsk. Every day here going on two-three propulsion. Strong earthquakes are called nine-Oimyakon earthquake in 1971. Tremors were felt in an area of one million square kilometers and sunk to Magadan. And in April 1989, between the valleys of the rivers Lena and Amur earthquake occurred in 8 points in an area of one and a half million square kilometers! Yakuts themselves assure that republic accounts for almost a third of the entire seismic Russia.
For 300 years the Urals noted 42 earthquakes of magnitude 3 to 6, 5 points. Recent studies suggest that there could be aftershocks and 7 points. True, it happens once in 110-120 years. Now as time goes seismic strengthening.
The last strong earthquake occurred March 30, 2010 near Kachkanar. In the midst of the power of shock was 5 points. The houses trembled glass, triggered car alarm in the car.
Of course, those who live in the central regions, is happening on the border regions of Russia may seem far away, but it turns out, there are events that affect the entire country. Thus, May 24, 2013 at the bottom of the Sea of Okhotsk at a depth of 620 kilometers there was a push force of 8 points. The quake was unique: it swept across the country and reached Moscow, becoming the fourth in western Russia over the past 76 years. This earthquake brought a lot of thrills inhabitants of the capital's skyscrapers. Some offices were evacuated workers.
