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...
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 ...
This earthquake sequence is of particular interest because it occured in a seismically inactive zone and include a rather long aftershock sequence. Two groups of epicenters were identified using a relative location procedure. Aftershocks observed during the first two weeks fall very close to the Bora...
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 ...
Epicenter The point on the Earth's surface directly above the focus or hypocenter of an earthquake (the point within the Earth where the earthquake originated). Inverse-gamma distribution A two-parameter family of continuous probability distributions on the positive real line, which is the distributi...
The point on the Earth's surface directly above the focus of an earthquake is called the ___.相关知识点: 试题来源: 解析 Epicenter 在地震学中,震源(Focus/Hypocenter)是指地球内部地震能量释放的起始点,而震中(Epicenter)则是震源正上方地球表面的对应点。题目直接询问地表对应震源的点名称,符合地震学术语...
"Based on all available data, a tsunami may have been generated by this earthquake that could be destructive on coastal areas even far from the epicenter," said the announcement from the National Tsunami Hazard Mitigation Program. Only six days ago a 5.5-magnitude quake shook Japan. The ...
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...
An earthquake's focus refers to the origin of the rupture, whereas an epicenter is the point on the Earth's surface that is directly above the focus...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer ...
