Earthquakes occur almost faults(断层), the areas where plates meet. About 80 percent of earthquakes occur around the Pacific Occan. Called the Ring of Fire because of the large number of volcanoes there, the area is a meeting point for many plates....
Usually, the plates move smoothly. But when they suddenly move several centimeters, pressure builds up where they are pushing into or against each other, so that earthquakes happen. Almost all earthquakes happen at faults. Most of the earthquakes happen along the coast. However, some happen in ...
15 Large earthquakes happen mostly along faults where tectonic plates meet as they move over the planet's surface.[...]plenty of smaller earthquakes, most not even felt by humans, occur across the world every day due to detonations, such as nuclear weapons testing or mining, or rising ...
- You know that most earthquakes usually occur along faults located near the boundaries between plates. (Most faults near plate boundaries are not the actual plate boundary itself but rather are related to the titanic forces associated with two giant plates grinding past one another.) ...
releasing the stored up stress energy to create an earthquake.Aslipis the distance rocks move along a fault and can be up or down the fault plane. Slip is relative, because there is usually no way to know whether both sides moved or only one. Faults lie at an angle to the horizontal ...
We know which areas are likely to have lots of earthquakes, and scientists can even identify faults where large quakes have happened in the past and might happen again. But there is no way to predict exactly when or where an earthquake will start. Sometimes there will be some small earthqu...
faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an ...
解析 1)Because faults usually form at the edges of the plates. And when the stress that builds up in the rocks along a fault is too much, the rocks break suddenly and an earthquake takes place. 2) In case of an earthquake. 3) (Omitted.) ...
4. Answer the following questions.1) Why do most earthquakes happen near the edges of the tectonic plates?usually form at the edges of the plates. And when the Because faults stress that builds up in the rocks along a fault is too much, the rocks break suddenly and an pearthquake takes...
at present dr johnson’s aspirations are limited to predicting the timing of an imminent quake. a full prediction would also need to include whereabouts along the fault it was going to happen and its magnitude. however, if ti...
