Mar 24, 2022 · Volcanic Eruptions. One of the major causes of earthquakes is volcanic eruptions. When boiling lava tries to break through the surface of the Earth, with the increased pressure of gases, certain movements occur in the Earth’s crust. This sends shockwaves through the Earth, causing damage. However, these earthquakes are mild and their range is ...
Earthquakes can have various effects, including ground shaking, damage to man-made structures, fires and hazardous chemical spills, landslides and avalanches and the generation of tsunamis in coastal areas. The severity of these effects depends on factors such as the earthquake’s magnitude, depth and local geology. Q6.
Solution. An earthquake is the shaking of the surface of Earth due to the sudden release of energy in the Earth’s crust, as a result, seismic waves (also known as S waves)are created. The seismic activities in an area determine the type and intensity of the earthquake.
Earthquakes can be classified into 4 different types. Learn more about the causes of earthquakes, p-waves, s-waves, shadow zones, measurement, types, fault types, shallow-focus and deep-focus earthquakes, earthquake clusters, induced seismicity, prediction, forecasting, and preparedness. Know more about the scales used to measure the magnitude and intensity of earthquakes. Download PDF (Free). For UPSC 2024 Preparation, follow BYJU'S.
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. ... When the rocks break, the earthquake occurs. Suggest Corrections.
The distribution of earthquakes in world is as follows: The Circum-Pacific Belt or the coasts around the Pacific Ocean are affected by earthquakes comprising the populated regions around the Pacific Ocean such as New Zealand, New Guinea, Japan, Alaska and the western coasts of North and South America. The volcanic activity around this belt is ...
Solution. The correct option is A Crust. Earthquakes are caused by tremors due to the shaking of ground. These tremors are caused by disturbances caused in the tectonic plates. These plates are deep down inside the uppermost layer of the earth called the crust. Suggest Corrections.
S waves. P waves are the first wave to hit the earth’s surface. These arrive after P waves. These waves travel in the speed range of 1.5-13 km/s. These waves are almost 1.7 times slower than P waves. These waves travel in a linear direction. These waves travel in a transversal direction. These waves can travel through solid, liquid, and gas.
Earthquakes are caused by a sudden release of stress along faults in the earth’s crust. The 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. The resulting waves of seismic energy propagate through the ground and over its ...
Earthquakes are triggered by tectonic movements in the earth's crust that occur suddenly. There is a continuous movement of tectonic plates. Orogeny occurs when the tectonic plates slide over one another, resulting in earthquakes. Vibrations spread in all directions as a result of these disturbances.
