another example. Tokyo earthquake in 1923, after the measurements on the seabed near the results showed that the seabed topography has changed a lot, where the fracture and dislocation occurred in a location,[link widoczny dla zalogowanych], cracks on both sides of the sea, while rising, while sinking, the level of difference 270 meters. 1933 Diexi earthquake, the mountains in the north, you can clearly see, the original continuous rock, like staggered like a clean break, crack up to 600 meters, about 80 meters down the wrong move.
most of the original ground fault earthquake is a sudden rapid dislocation caused by a small number is due to rupture of the crust produced by the force of a new fault occurs. According to statistics, more than magnitude 7 earthquake in more than 80% below the fault zone.
100 kilometer-long crack is very long, but April 18, 1906, the western United States earthquakes along the Pacific coast, 450 km-long crack appeared! Therefore, housing, fences, roads ... ... the phenomenon is the wrong move, more significant and widespread. Many of the thick buried water pipes are breaking; San Francisco after the fire due to vibration, but not so much water to put out flames that fly, and constantly spread by the burning of the region, an area of over 10 square kilometers. After seismologists study, the original of this early with the existence of the underground cracks, but cracks on both sides of the site being in a stable state, it usually does not feel shock, then they slip a bit, so a strong shock occurred.

but some earthquakes, do not see the ground breaking heave phenomenon, which may be broken in too deep, did not cause significant changes in the surface. As thick as the end of the plain is easy to see the steps of the fracture dislocation is a rare phenomenon, many faults, where we need to research the rock underground was able to recognize. The split of the ground during the earthquake occurred, not all fracture dislocation formation, many of the surface debris 被震 opened, or because of other causes.
1556 earthquake in the vicinity, but also because of the Weihe Plain with the ground between the Qinling Mountain, has long hidden the cracks and the site has repeatedly increased the south, the north side of the site will continue to sink, thus creating the cliff and plain tight connected to the terrain, this time cracking down on both sides of the site again, it had a severe vibration.
1973 年 2 6, Ganzi Tibetan Autonomous Prefecture of western Sichuan 7.9 magnitude earthquake occurred, the ground has also created a lot of cracks.
This is because the ground had cracks, fracture dislocation of land on both sides of the location, crack their path, whether it is housing or roads in a split in two, there is a crack stretching from southeast to northwest about 100 kilometers, cracks on both sides of the land along the horizontal direction dislocation of 3 meters, where the most powerful heave up and down the difference can reach 6 meters in the field have been flat to form a huge step.
1835 earthquake in Chile, Concepcion Simpson Santa Maria Island, southwest of the city have increased by 3 meters, the island off the edge of the original one are often located under the sea rose over the rocky beach. In this earthquake before, in 1822 another major earthquake in Chile, more large-scale increase in the phenomenon, an estimated 259,000 square kilometers of area increased at an average increase of nearly 1 meter. In 1960 Chile earthquake, was observed in southern Chile, 320 km long coastline, generally sank as much as 3 meters.

1755 Lisbon earthquake in Portugal, many people fled to a new pier with a refuge of marble, thought it was a safe place, because the rubble of collapsed buildings when the avalanche is not easy to achieve here. Who knows with this terminal is a more terrible place. Suddenly, the whole terminal, together with the people above all sink into the sea, never to rise up. There are also sunken park in the Gulf of many of the vessels open sea like a devil big mouth, swallowed it all. Yes, indeed there is such a huge mouth, where the earth had opened, and when the terminal after subsidence, it closed up, so things never float subsidence.

Nobi Plain in Japan, the seismic traces left behind breaks in heave, in particular.
Also in 1976, February 4 in Guatemala's 7.5 earthquake, the northern part of the country westward at least 1 meter above the level of dislocation in some places from 3.25 meters.
Nobi Plain, Honshu Island in the waist, surrounded by mountains, south sea, vertical and horizontal plains criss-cross paths, rice paddies widespread, is famous for rice production, known as the Japanese garden. October 28, 1891 6:00 o'clock in the morning, the earth suddenly shook violently, like a papered houses have collapsed, and it would have destroyed more than 270,000. The river embankment has been shattered, and about 500 kilometers of dike rehabilitation needs. Wait until after the cessation of violent shaking, frightened little people set, look around, I saw the earth has changed its appearance, neatly connected together before the earthquake staggered field path; houses and trees move as they will walk like the location ; originally ran in the north to the south of the tree; did get very close neighbor, has now become non-adjacent; original tracks straight, and now becomes a winding.
Mountains, the Helan Mountains and their piedmont between the lowlands, and there are cracks in the rising side of the mountain is, the ground is sinking on one side, so far heave change from time to time, so frequent earthquakes.
carefully observed it, most earthquakes, the crust of the rock is fractured dislocation caused by this ground breaking and move the location of the phenomenon, known as the fault; also known as the fault of these earthquakes earthquake. Some of the original fault earthquake is the result of the fault re-activity, while others are emerging as a result of the fault. 1891 earthquake fault in Japan, is new; 1906 earthquake in the western United States, in addition to the original fault re activities, but also generated new faults in the San Francisco underground faults to just have a new adoption, so particularly strong shock .
Tangshan Earthquake, which is the existence of underground faults. In this earthquake, not only can detect faults on both sides of the site in the horizontal and vertical directions relative to the location of movement occurred, and in some places on the ground can be clearly seen; horizontal displacement distance of up to 1 meters, the vertical displacement of tens of centimeters away from there.
