THE RICHTER’S SCALE 1 -2 mark People do not feel the change. 3 -4 mark There is a slight movement of the chandelier, the clatter of dishes, etc. 5 -6 mark Falling small items. 7 -8 mark There are small cracks in the walls and ceilings. 9 -10 mark The destruction of buildings. 11 -12 mark Grand destruction and a large number of victims.
Seismograph - the device to automatically record the Earth's surface vibrations created by seismic waves.
UKRAINE NICHT SEISMOLOGISCHEN ZONE, WEIL IN UNSEREM LAND ERDBEBEN SIND SELTEN UND FAST UNSICHTBAR (2 -3 PUSH)
IN THE NIGHT FROM FRIDAY TO SATURDAY (24 SEPTEMBER) IN THE CAPITAL, AS WELL AS OTHER CITIES OF UKRAINE PASSED A LIGHT EARTHQUAKE - ABOUT TREMORS MASSIVELY INFORM USERS OF SOCIAL NETWORKS. BASED ON THE DESCRIPTION OF THE PHENOMENON, THE MAGNITUDE OF THE SHOCKS ARE UNLIKELY TO EXCEED 3 -4 ON THE RICHTER SCALE. SEISMIC ACTIVITY "HAS COME" TO UKRAINE FROM ROMANIA, THE SCIENTISTS SAY.
Over the last 250 years, earthquakes have been recorded in Kiev in 1790, 1793, 1802, 1829, 1838, 1908, 1940, 1977, 1986, 1990, 2004. October 27, 2004 "jolted" by four points, on May 30, 1990 - 5 points. Until recently, Kiev is not included in a seismically dangerous zone, now these revised standards. The old building was carried out with the expectation of 5 points, such shocks are not dangerous, will not lead to collapse. Now the home above 25 floors (about 80 -100 m), their number in the city, are considered especially dangerous objects, so they laid a large supply resistance. Six-point tremors they will certainly survive, but can cause cracks in the walls. After all, the higher the building, the greater the fluctuations on the upper floors. But frames can withstand load houses. Thus, shocks to 6 points for the Kiev are acceptable risk.
Science and Earthquakes. Fortunately, earthquakes can be predicted and people have a chance to protect themselves. Space plays an important role in prediction of the earthquakes and other disasters.
