7 An earthquake is the perceptible shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's crust. This sudden motion causes shock waves (seismic waves) to radiate from their point of origin called the focus and travel through the earth. It is these...
To enhance the understanding of this earthquake, we converted the earthquake epicenter and magnitude with empirical formulas based on the distributions and areas of the coseismic landslides. Comparing with coseismic landslides in other earthquake-hit areas, we found the capability that this earthquake ...
Earthquake Epicenter | Definition & Location from Chapter 21 / Lesson 15 232K What is the epicenter of an earthquake? Learn the epicenter definition, where to find the epicenter of an earthquake, and why we need to find the epicenter. Related...
this earthquake seemed to be stronger to people in Fukushima. This is because the epicenter was closer to the region, and the distance of epicenter was about 10 kilometers, which was shallower than the 2011, and therefore the physical experience was stronger than the p...
The location below the earth's surface where the earthquake starts is called the hypocenter(震源),and the location directly above it on the surface of the earth is called the epicenter(震中).可知,震源在震中的下面,断层面是板块之间的断截面。故选C。 根据本段的Since the edges of the plates ...
根据第三段The researchers found that 90 percent of all reported cases happened within 62 miles (100 kilometers) of the epicenter(震中)and within 60 days of an earthquake.Then,they examined when and where foreshocks(前震) had happened in the region. "The space-time pattern of animal ...
Textbooks commonly illustrate earthquake P and S wave shadow zones using ray tracing techniques with an epicenter at the North Pole and the shadow zone south of the equator. Shadow zones differ for earthquake locations else where. Shadow zones for earthquakes at locations around the world can be ...

At the Earth's surface, earthquakes manifest themselves by a shaking and sometimes displacement （位移）of the ground. When a large earthquake epicenter （震中）is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami（海啸）. The shaking in earthquakes...
