Earthquakes

Слайд 3The vertical motions lead to a drastic lowering or raising

of the rocks. Typically, the offset is only a few

centimeters, but the energy released when moving billions of tons of rock, even a small distance is enormous.

The vertical motion

Слайд 5
This sudden release of energy stored in compressed or stretched

rocks.
It manifests itself in tremors and vibrations of the earth's

surface.

Слайд 6The second reason reflects deeper processes occurring in areas along

the edges of the shifting plates, where the edges of

these masses are immersed in the Earth's crust Earth's mantle at depths of about 500 km re-absorbed, absorbed. For this reason, there are already more major earthquakes

Causes of earthquakes

The second reason reflects deeper processes occurring in areas along the edges of the shifting plates, where

Слайд 8Irishman Robert Mallet distinguished engineer has made a significant contribution

to the study of earthquakes. He found that there are

certain zones where occur most frequently small or large earthquake.
Mallet mapped the areas in which seismic waves propagate, we found that all of them, like rays from the star, emanate from a single point - the epicenter located at the ground surface above the earthquake

Слайд 9The first seismograph, which had scientific value, was built in

1879 in Japan, Ewing. As the cargo was for a

pendulum cast iron ring weighing 25 kg, suspended on steel wire.

Слайд 10Currently, inducted into the practice of monitoring large areas: near

the major faults are placed devices on which information is

transmitted via satellite connection to the centers, where is processed.

The prediction of earthquake

Слайд 11Другой метод основан на определении содержания воды в породах. В

напряжённых породах происходит увеличение объёма пор, а тем самым и

водосодержания.
Издавна известно, что люди использовали более чутких животных для предупреждения о возможной опасности.

Not bad a presentiment of natural disturbances and attack pets.

It is well known that dogs, chickens and pigs shortly

before the onset of disasters are changing their behavior, give in to apathy and refuse to eat.

Animals - predictors

Not bad a presentiment of natural disturbances and attack pets. It is well known that dogs, chickens

Слайд 13. Snakes, especially poisonous, in anticipation of an approaching earthquake

is a few days leave the inhabited burrows. So do

lizards and ants. Some scholars are inclined to explain this undeniable fact highly sensitive to temperature changes in the skin of the soil

Animals - predictors

Слайд 14As part of the ESP is not inferior to reptiles

and crocodiles.
December 17, 1987 on the island of Kyushu, dozens

of individuals have begun to publish an alarming growling and bending arch, perform an intricate dance.

prevent at least 130 animals.

Слайд 16 A new type of earthquake, Japanese scientists discovered. Earthquake, described

by researchers led by Professor Ito Iosihiro have ultra-low frequency.

Identified seismic processes can lead to fluctuations in the magnitude 3 to 3.5 points. However, the shocks are so slow that their man does not feel. However, these variations contribute to the growth pressures in a seismically active zones.

The new data
