5(a)The magnitude of an earthquake is measured by the Richter scale. The magnitude, M, can be determined by the equation M =1, where I is th intensity of seismic waves recorded by seismographs and I, is a constant which represents the threshold intensity.(i) State the magnitude of an...
An earthquake's degree is a measured value of its size and is the same no matter where you are, or how strong or weak the shaking was in different locations. An earthquake's intensity is a measure of the shaking it creates, and varies with location.A degree of 8 or higher defines a...
When the earthquake occurred it is essential to have a clear-headed calm composed attitude. Only calm and peace will it be possible to use knowledge learned in the earthquake and determine the size of the earthquake near and far. Chang Chun-under over the last bumpy start after about swing....
or the related and mostly obsolete Richter magnitude(里氏量级）, with magnitude 3 or lower earthquakes being mostly imperceptible 感觉不到的 and magnitude 7 causing serious damage over large areas. Intensity of shaking is measured on the modified Mercalli scale（麦加利震级, 麦氏震级）....
You may notice things moving on shelves, but (4)s you may feel a sharp jolt(强烈的晃动) or hear a low rumbling noise(隆隆作响).The intensity(强度) of an earthquake can be measured (测量) . One measurement is called the Richter scale(里氏震级). Earthquakes below4.0 on the Richter ...
阅读理解 Earthquakes are measured on a scale designed by U.S.scientist called Charles Richter.Each increase of one whole unit means a tenfold increase in intensity.That is to say an earthquake o
Other damage results from landslides or major fires which are initiated by the quake. 2 There are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from 0 upward. The highest ...
although there is no limit to the possible magnitude. The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 (as of March 2011), and it was the largest Japanese earthquake since records began. Intensity of shaking is measured on the modifi...
Earthquakes are measured on a scale designed by U.S.scientist called Charles Richter.Each increase of one whole unit means a tenfold increase in intensity.That is to say, an earthquake of 7.0 is ten times more powerful than one of 6.0 and 8.0 earthquake is 100 times stronger than a 6.0 ...
