The largest earthquake in history has fallen on Russia: that made it so large -scale
The US Geological Service reported that an earthquake that struck Kamchatka, the Far East of Russia, was shallow-its epicenter was at a depth of about 19 kilometers and 119 kilometers southeast of the remote city of Petropavlovsk-Kamchatsky, whose population is about 165,000 people, writes indent.

While the Richter scale has traditionally been used and effective for regional magnitude earthquakes up to 5 points, the momentary magnitude scale is used for stronger shocks because it takes into account more factors such as the amount of fault. The scale of earthquakes is measured on a logarithmic scale: in simple words, an earthquake of magnitude about 9 points 1000 times more powerful than an earthquake of magnitude 6 points.
Some of the largest earthquakes in the history of the Earth are known to be preceded by "forshocks". However, such small shocks cannot be identified as fops until a larger earthquake in the same area. In the case of Russian earthquake, scientists have recorded several forks that have occurred in the region over the last month. According to the US Geological Service, a magnitude earthquake 7. 4, registered in the region of July 20, can now be considered a forded earthquake that happened on July 29.
According to Seismologist Harold Tobin, director of the Pacific Northwestern Seismic network of Harold Tobin, scientists recorded a clear subduction jump, as well as another magnitude event above 8. 5 with a noticeable forshock, as in Tokhok in 2011. Despite the fact that the 8. 8 magnitude was affected by the large earthquake, the number of people living in the region and its environs was "limited".
According to another seismist Dimas Salomo Sianpar, it is also remarkable that the Russian earthquake was preceded by a series of forks, including an earthquake of magnitude 7. 4 and three earthquakes of magnitude 6. 6, as well as a series of weaker underground shocks, fixed directly in front of the main earthquake.
It should be noted that a large earthquake in the remote region of Russia suffered several people, and Japan warned about tsunami - it was expected that waves could reach 3 meters in height. The US Tsunami Tsunami Warning System has also released a warning about Tsunami Dangerous Waves for the next three hours.
The destruction caused by the earthquake is often dependent on a number of factors, such as the distance from the epicenter of the earthquake, the architecture of the region and the density of the population, as well as the depth of the earthquake and the geological conditions that surround it, as well as the consequences, such as tsunami.
