Why do earthquakes happen? Scientists explain that the outside of the earth is made of a number of different plates(极块). For example, at San Francisco the Pacific Plate which is moving towards the northwest meets the North American Plate. The Pacific Plate is moving very slowly-at 5. 3...
There's not much we can do to stop natural disasters likeearthquakes: they're an inevitable part of living on a planet like Earth, seething inside with hidden power. What we can do, however, is monitor changes in the ground beneath our feet so we can predict when earthquakes will happen....

Are there earthquakes or hurricanes and, if so, how can the bridge be designed to survive them? Will a river bridge be able to cope with floods? And what about the loads it will carry? If it's a road bridge, how much is traffic likely to increase over the coming years and decades,...
The fault is known for producing slow-motion earthquakes, called slow slip events. These can release pent-up tectonic pressure harmlessly over days and weeks. Scientists want to know why they happen more often at some faults than others. ...
allowing evolution to happen. Even small amounts of water deep below the surface are known to dramatically increase rock plasticity, which is essential for plate tectonics — a process that shapes the continents and oceans, and drives earthquakes and volcanism. But despite its huge importance for ...
The alt text reminds me of how Earthquakes are depicted in movies, where a massive rift opens up in the Earth.162.158.75.1013:48, 9 August 2017 (UTC) I was totally expecting the Amigara Fault in there108.162.216.11214:10, 9 August 2017 (UTC) ...
Some countries,such as Japan,have a large number of earth quakes.Earthquakes happen very 1 and violently(强烈地).During an earthquake,there is often a great 2 first.Then the earth 3 terribly,many houses 4 ,railway tracks break and trains run 5 lines,a great many factories are 6 ,thousands...
What are the most common types of Archean rocks and how are they thought to have formed? Regions along a major fault that are locked and not releasing energy are prime sites for future earthquakes and are known as a. epicenters. b. foci. c. hypocenters. d. dis...
It caused big fires,storms,acid rain,and even earthquakes and volcano eruptions.The hit produced a lot of dust,which flew up into the air and blocked the sun for months.The earth became very cold without sunlight.The plants died first.Then the grass-eating animals died of hunger.Then the ...
