An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak ...Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. The Richter scale is used to determine the intensity of earthquakes, and a seismograph is a device that shakes with the ground during an earthquake. This movement is recorded by using ink to draw lines on paper that is constantly being move...Measuring Earthquakes Earthquakes are measured either in terms of the magnitude or intensity of the shock. Earthquake magnitude is measured on the Richter scale (named after the seismologist who devised it). The magnitude implies the energy released during the earthquake and is expressed in numbers 0 to 10.An earthquake of magnitude 4.3 jolted Myanmar on Monday morning, the National Center for Seismology (NCS) said.
