Families in western Afghanistan, who have lost everything to a series of devastating earthquakes, need urgent assistance to withstand …Sometimes plate edges get stuck because of friction but the rest of the plate keeps moving, very slowly. 3. The energy and pressure that move the plates get stored up at the edges. 4. When the energy and pressure build up enough to overcome the friction, the plates move past each other along the fault. 5.How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.The distribution around Earth of earthquake activity varies greatly. There are places where natural earthquakes occur quite commonly, of a range of strengths from small to extremely large, because these are boundary zones between large tectonic plates. There are other places where earthquakes are infrequent and small, typically in places within ...

For example, the 1964 Niigata earthquake caused widespread …Ground shaking Ground shaking can be caused in various ways (volcanic tremors, avalanches, large explosions, etc.), but shaking intense enough to cause damage is usually due to rupturing of the Earth's crust known as earthquakes. The intensity of shaking depends on several factors: ….

The earthquake magnitude is a measure of the amount of seismic energy released by it, so it is a quantitative scale. Magnitude is the most commonly used measure to describe the overall strength or size of an earthquake. The magnitude of an earthquake is expressed in decimal fractions and whole numbers.The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes.Strengths and limitations of this study The present study employs a longitudinal pan-el design with five measurement points to study (pschosomatic) health consequences of man-made earthquakes caused by gas extraction.
