Earthquakes are recorded by instruments called seismographs. The recording they make is called a seismogram. The seismograph has a base that sets firmly in the ground, and a heavy weight that hangs free. When an earthquake causes the ground to shake, the base of the seismograph shakes too, but the hanging … See more 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 orfault plane. The location below the earth’s surface where the earthquake starts is … See more The earth has four major layers: the inner core, outer core, mantle and crust. The crust and the top of the mantle make up a thin skin on the surface of our planet. But this skin is not all in one piece – it is made up of many pieces … See more The size of an earthquake depends on the size of the fault and the amount of slip on the fault, but that’s not something scientists can simply measure with a measuring tape since faults are many kilometers deep … See more While the edges of faults are stuck together, and the rest of the block is moving, the energy that would normally cause the blocks to slide past one another is being stored up. When the force of the moving blocks finally … See more WebApr 9, 2024 · Seismic waves generally travel much shorter distances on the West Coast than on the East Coast because: A. earthquakes are more frequent on the West Coast. B. the soil composition is different in the two regions. C. the earthquakes are of a greater intensity on the East Coast. D. communities are better prepared for earthquakes on the …

WebJul 27, 2024 · The energy from an earthquake travels through Earth in vibrations called seismic waves. Scientists can measure these seismic waves on instruments called seismometer. A seismometer detects seismic waves below the instrument and records them as a series of zig-zags. Scientists can determine the time, location and intensity of … WebIn the form of seismic waves (like water ripples), the escaping energy radiates outward from the fault in all directions. The seismic waves shake the earth as they move through … WebEarthquakes shake the ground because fault rupture releases vibrations that radiate in the form of seismic energy.
