The main reason for the consequences of any tragic earthquake - strong shaking of the upper layers of the soil, caused by who came from the source of seismic waves.
These shaking during large earthquakes cause numerous processes and phenomena, which are divided into primary and secondary effects of earthquakes.
Primary effects zemletryaseniyK primary consequences of an earthquake or, in other words, direct, include:
damage, collapse and destruction of buildings, structures or parts thereof
damage and rupture of pipelines, power lines and communications, roads
violation of infrastructure, entailing death and personal injury, loss of wealth | uneven subsidence and liquefaction under the foundations of individual buildings and structures, leading to their inclination, damage or destruction
vibrations of buildings and structures that contribute to the fall of the equipment and unstable objects, which in turn leads to the death and injury of people and the economic damage
vibrations of buildings (often accompanied by an underground buzz, rattle parts of the building, a roar of falling objects), leading to massive stress people, a panic and, as a consequence, to complicate the evacuation and rescue operations, additional injury to people in the building
landslides, avalanches, glaciers partial similarity, other seismogravitational deformation
damage or destruction of dams, huge masses of soil creep in the reservoir, leading to flooding of vast areas, the destruction of buildings in the lower reaches of the river.
P.S. Сама учителю на днях сдавала :з У меня тут небольшая путаница со знаками препинания, но думаю, разберешься. Рада была помочь.
