Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.) Because the size of earthquakes varies enormously, it is necessary for purposes of comparison to compress the range ...Ang intensity ay ibinabase sa pakiramdam ng tao at epekto nito sa paligid. Habang papalayo ang lugar mula sa epicenter, papahina nang papahina ang nararamdamang "intensity" o pagyanig. Tulad halimbawa ng nangyaring lindol sa Luzon nitong Lunes na naitala sa lakas na magnitude 6.1, at intensity V naman ang naging sukat ng lakas nito …So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. Magnitude scales, like the Richter magnitude and moment magnitude, measure the size of the earthquake at its source. So they do not depend on where the measurement is …The Modified Mercalli Intensity Scale of 1931 is the basis for the U.S. evaluation of seismic intensity.Intensity is different than the magnitude in that it is based on observations of the effects and damage of an earthquake, not on scientific measurements.This means that an earthquake may have different intensities from place …Magnitude vs. Mercalli. Though it’s the magnitude rating that makes the news, it’s the Mercalli rating that more accurately describes the effect of the earthquake on local residents. A good example of this difference is a comparison of the devastating 2011 Christchurch earthquake and a much larger magnitude earthquake that struck the area ...

The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.The 2010 earthquake, 7.0 magnitude, struck about 15 miles west of Port-au-Prince, ... because that quake gave Intensity VII shaking to Port au Prince," seismologist Lucy Jones said on Twitter.VL #6 - SCIENCEThis video lesson discusses the difference between MAGNITUDE and INTENSITY in a very simple manner and comprehensive explanation.This Video Le...The energy of an earthquake can be calculated from the moment magnitude scale value alone.
