Earthquakes Questions And Answers

Earthquakes are caused when two blocks of earth suddenly slip past one another. The surface where the two blocks slip is called the fault. The earthquake starts below the earth’s surface at the hypocenter, and the location above the hypocenter is called the epicenter. Earthquakes can have foreshocks which is a smaller earthquake that happens before the larger quake. Earthquake can also

Earthquakes typically occur in relation to other earthquakes. After shocks that follow earthquakes, typically occur around the same fault break as the original earthquake or can occur on nearby fault lines as well. Earthquakes can also be triggers for future earthquakes occurring on the same fault line or neighboring fault lines anytime from seconds to years after the orginal mainshock. “In recent decades, scientists have learned that faults and earthquakes communicate with one another in far more diverse and interesting ways than the classic foreshock – mainshock – aftershock” (Hough 1).

Yes Dasha i can, the process of an earthquake first starts of with the foreshock. When an aftershock is larger than the actual earthquake, the earthquake becomes a foreshock, and the aftershock becomes known as the main earthquake. An aftershock is the shaking that occurs after the earthquake. There usually a small break of which there is no shaking between the earthquake and aftershock.

Earthquakes have been recorded throughout history for thousands of years. Even before seismographs in early times, there are records and accounts of mysterious ground shaking. Earthquakes occur when rocks break along an underground fault (UPSeis, 2007). This, in return, causes vibrations through the earth which causes ground shaking. The magnitude of the shaking varies depending on how great the movement along the fault is; the greater the movement, the bigger the earthquake. Some earthquakes are huge and cause significant damage, while others are small and cause little or no damage what-so-ever. Earthquakes are unpredictable, and can happen at any time. It is uncertain where an earthquake will strike, but there is a greater risk

What is an earthquake and why do they happen? : An earthquake is vibrating of the ground caused by the rapid breaking and motion of large parts of the earth’s rocky outermost crust. Earthquakes

The most common cause of earthquakes is movement along faults. Earth’s crust is divided into tectonic plates, which grind past each other at fault boundaries. As tectonic plates move,

Earthquakes are sudden trembling or shaking vibrations. Earthquakes are large spinning spiral winds, that comes together by rocks underground breaks along the fault. There are two types of earthquakes, there is the body waves and the surface waves. Body waves travel at 7/8 km. The body wave is the fastest of the two waves. The surface waves act as a gravity waves that are between two fluids with different density. Unlike hurricanes,

“Discuss the view that the impact of earthquake hazards depends primarily on human factors (40)”.

When the rocks underground suddenly broke along a fault, one side of the fault slipped. A fault is a thin zone of crushed rock separating blocks of the earth's crust. The rocks then began rubbing against each other, and catching. After a while, the rocks broke because of all the pressure that was built up. When the rocks broke, the earthquake occurred. During and after the earthquake, the plates or blocks of rock started moving, and continued to move until they eventually stuck. The spot underground where the rock broke is called the

When the fault ruptures, a P-wave comes first. Then comes the S-wave. The S-wave is more destructive. There are sensors that can identify the P-wave. This information is sent to an earthquake alert center. The earthquake alert center starts to determine where the earthquake is happening and how big the earthquake is. Then this information is sent to your phone or your computer as a message. This will give you a warning and notify you of the intensity of the earthquake and when it will arrive in your location. Geologists still can’t predict when an earthquake will happen but they are able to send you a warning when the earthquake does

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault of fault plane. The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. There are four types of earthquakes tectonic,volcanic,collapse,and explosion. Another good topic to study is deeper into the science of earthquakes. ”Most earthquakes occur along faults, or breaks, in the Earth's crust.” by Bill Haneberg.http://tremor.nmt.edu/faq/what.html

Ultimately, to fully comprehend a specific earthquake one must know how earthquakes form as well as, how they work. An earthquake is the shaking and vibration of the Earth 's crust. This happens when two blocks of the earth suddenly slip past one another

     An Earthquake is the shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. The sudden shaking of the ground that occurs when masses of rock change position below the Earth's surface is called an earthquake. The shifting masses send out shock waves that may be powerful enough to alter the surface of the Earth, thrusting up cliffs and opening great cracks in the ground.

Inc.). The book, Predicting Earthquakes, the author points out "There are generally three kinds of faults: normal, reverse, and strike-slip. By careful observation and measurement, geologists, acting like detectives, can tell how much a fault moved, which part went up, which part went down, and which way the fault moved" (Vogt 26). "When one of the plates slip under the great amount of stress at the fault, an earthquake occurs. The shaking we feel are the passing of long waves" (Putnam 443). "The L-waves (long waves) travel at slower velocities that the primary and secondary waves. These waves make the largest squiggles on a seismograph but their effect diminishes rapidly with distance. The L-waves are limited to the crust" (Putnam 443).
