Earthquake definition simple
Earthquake definition simple-An earthquake is like Earth having a really bad day Energy builds up underground when plate boundaries push, pull, or rub against each other After a while, the stress becomes too much to handleIntroduction to Earthquake An earthquake is a sudden shaking movement of the surface of the earthIt is known as a quake, tremblor or tremor Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities
An earthquake is caused by a sudden slip on a faultThe tectonic plates are always slowly moving, but they get stuck at their edges due to friction When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel In California there are two plates the Pacific Plate and theAn earthquake is caused by a sudden slip on a faultThe tectonic plates are always slowly moving, but they get stuck at their edges due to friction When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel In California there are two plates the Pacific Plate and the3 Earthquake design spectra Given a earthquake ground acceleration, there is no difficulty to compute response using Newmark's method as the previous example Therefore, we can generate a response spectrum for that earthquake We are interested in the maximum relative displacement, velocity, and total accelerations
Earthquake shaking can cause landsliding on many scales, as some of these examples show An earthquake can cause a slope to become unstable by the inertial loading it imposes or by causing a loss of strength in the slope materialsA powerful earthquake can cause landslides, tsunamis, flooding, and other catastrophic events Most damage and deaths happen in populated areas That's because the shaking can cause windows to break, structures to collapse, fire, and other dangers Geologists cannot predict earthquakesDefine earthquake intensity earthquake intensity synonyms, earthquake intensity pronunciation, earthquake intensity translation, English dictionary definition of earthquake intensity n pl in·ten·si·ties 1 Exceptionally great concentration, power, or force 2 Physics The amount or degree of strength of electricity, light, heat, or

Earthquakes glossary Active fault = an active fault is one that has moved once or more times in the past 10,000 years and therefore likely to move sometime in the future Aftershocks = smaller earthquakes that occur after the main earthquake in the same place as the mainshock Aftershocks are linked to the size of the mainshock and if this is large can continue for many weeks, months or yearsEarthquake focuses originate at different depths (h) Most of them occur in the earth's crust at depths ranging from to 30 km A large number of shocks originating in depths of hundreds of kilometers (upper mantle) have been recorded in some regions An earthquake is a powerful manifestation of the interior forces of the earthAn earthquake takes place when two blocks of the earth suddenly slip past one another The surface where they slip is called a Fault place The location below the earth's surface where the earthquake starts is called the hypo center, and the location directly above it on the surface of the earth is called the epicenter
