earthquake in Buryatia - a phenomenon by no means rare.This is explained by the geographical location of the Republic: located on the territory of the Baikal Rift, it is doomed to experience periodic outbreaks of seismic activity.
Theoretical training
The cause of the tremors is different: artificial due to human factor, natural - natural forces.Most of the most destructive earthquakes are of natural origin and occur as a result of the collision of enormous layers of the earth's crust, called tectonic plates, or platforms.Each year, these tremors occur about a million - and most of them go unnoticed.
How to measure the power of an earthquake
place the earth's crust, where it is offset and where seismic waves propagate, called the hearth, and the surface of the planet over it - the epicenter of the quake.At this point, the most powerful tremors.
customary to talk about intensity and magnitude earthquake.Often these concepts are confused - and in vain, they are completely different things.The intensity of an earthquake is measured by its impact: 1-point can be registered only seismograph, a 12-point changing terrain and is the absolute destruction.
seismograph - a device that measures the magnitude of an earthquake.For this purpose most often used Richter scale of 1 to 9.5 divisions.When shocks to 5 points in the room swaying objects, up to 6 - are formed cracks in the walls.With 9 points unavoidable great destruction.An earthquake with a magnitude of 9-point occurred in 2011 in Japan - the consequences were terrible (and it is in a prosperous country that is no stranger to seismic activity).
Where to wait earthquake
If you look at a map, it is easy to see that the earthquakes have certain "lines" in the world.In the world there are two seismic zones: the Mediterranean, Asia and the Pacific "ring of fire."
danger from this point of view areas in Russia about 28%.9-point earthquake possible in Baikal, Kamchatka and the Kuril Islands.Thus, Belarus is one of the most prone to strong earthquakes the country.
most impressive earthquake in Buryatia has occurred in 1862 - then the water went Tsagan steppe area of 230 square km, and formed a new Bay of Lake Baikal, called the failure.
Seismic activity of recent years
According to the MOE, the last 7 years in Buryatia more than 500 seismic events of varying intensity.
ranked in the national press earthquake in Buryatia in 2011 was December 27: Tove jolted by 6.7 points.But local media reported on January 26 tremors (5.3 points), February 2 (6.7), May 28 (5.4), July 17 (5.9).Seismologists have started talking about the fact that such activity is not good.A series of aftershocks could presage a strong earthquake in Buryatia, which take place in the country about once every 60 years.
However, experts are cunning: a method to predict the nature of this phenomenon does not exist, but has long been struggling with the problem, scientists from many countries.Fish and pets have a notable success: some time before the earthquake dogs, cats, parrots and even the inhabitants of the aquarium exhibit anxiety, seeking to break out of the limited space.At many stations of seismic experts observe the behavior of animals, some of them are able to predict an earthquake a few hours or even days in advance.
But back to the seismic situation in Belarus
In 2013, the total number of earthquakes has exceeded one hundred, but fixed the press about five.The magnitude of the aftershocks of the strongest of them was 4.6 points.By the standards of the country, it is almost nothing.
next year has been fruitful.An earthquake in Buryatia 12 August 2014 in force 4.2 points was not the first who got into print - in May, the republic shaken by 6.5 on the Richter scale.That's pretty much - but, fortunately, the epicenter was located far from settlements, destruction and there were no casualties.In November registered the tremors of magnitude 4.8 points, and December 7 was the latest in a calendar year, the earthquake in Buryatia.2014 ended, started in 2015 - and the situation has not changed: January republic "shaken" more than 30 times, the strength of aftershocks ranged from 3.2 to 4.5 points.
reading free press
What a good event for the news sites - an earthquake.Republic of Buryatia in this aspect - a bonanza for the media: the population is frightened, professionals can once again cross swords and long discussion on the subject, as are large-scale destruction in Ulan-Ude, rock this place score 8-9.Discussions of these, unfortunately, is not groundless.Had such a strong earthquake in Buryatia inevitable severe damage: a huge part of the buildings in the capital do not meet seismic safety standards.
Meanwhile, for the person interested in the topic, two things are clear:
1. Statistics of seismic activity in the area of open access no.Interested parties can, of course, familiar with relevant publications in the media, but the feeling of "a certain vagueness" remains.
2. Information on the seismic characteristics of the Buryat buildings in the public domain again not.And it's a little alarming.
Lessons of Life Safety
Every resident of dangerous region should know how to behave during an earthquake.
-
If the element found in the building, do not try to go out: it is better to sit on the floor in one of the interior angles of the apartment, to stand in the doorway, clutching the shoals, or get under a heavy table, and take up his legs.On the external walls, windows and mirrors need to stay away.In no case can not use the elevator: it can jam between floors.
-
On the street you must go to an open space as possible without approaching shaking the walls, bursting glasses or scraps of wires.On the shore of the sea (lake) is better to stay on the hill so as not faced a wave.
-
If an earthquake overtaken in the car should be driven away from bridges, overpasses and trees should stay inside: some no, and protection.
