On average, the earthquake lasted about a minute.
Aftershocks can happen and one year after the earthquake. Aftershocks happen because of the fact that the reset line and shifted the Earth's crust come to equilibrium after the main earthquake. After a major earthquake aftershocks may last for years.
Parkfield, a town in California called the "Capital of the earthquake." It is a bridge that connects the two tectonic plates.
Basically earthquakes happen because of geological problems, but sometimes they can be caused by landslides, explosions in mines, nuclear tests and volcanic activity.

In the northern hemisphere occurs more earthquakes than on the opposite side of the globe.
The biggest avalanche caused by the earthquake, went to Peru. The huge mass of a mixture of ice, mud and stones came down with a speed of 400 km per hour from Mount Huascaran and razing entire villages, destroyed more than 18 thousand local residents.

Zhang Heng, a famous astronomer from China, invented the first detector earthquake nearly two millennia ago. This device was able to fix the earthquake, the epicenter of which was located at a distance of 600 kilometers.
About 80% of the largest terrestrial oscillations occur in the "Belt of Fire", which is in the form of a horseshoe stretches of the Pacific Ocean in the place of "meeting" many tectonic plates. The second most common area of ​​the earthquake was in an area that covers Turkey, India and Pakistan.
Earthquakes can trigger volcanic eruptions, as happened with Mount St. Helens in 1980 and before the eruption of Mount Etna in the beginning of the third millennium (2002).

The strongest earthquake in recent history occurred in 1960 in Chile. Giant ocean waves after this catastrophe spread over a distance of 6000 kilometers from the center of oscillation of the crust.
The limit of the measured seismic velocities of 360 kilometers per hour.
Before the earthquake of some reservoirs may come unusual odor, due to an increase in the intensity of the emission of gas from the earth's crust. Also, the temperature of parts of the crust may begin to rise.
Strong earthquake under the ocean floor caused tsunami waves that spread in all directions to a distance of 1,000 miles. When this wave reaches the shore, she suddenly grow up, can cause terrible destruction.
