  • nepal earthquake aftershock near mount everest sends

    the magnitude-7.3 quake centered midway between kathmandu and mount everest struck hardest in the foothills of the himalayas triggering some landslides but it also shook the capital badly

  • the richter scale - how earthquakes are measured

    earthquake magnitude is measured on a scale created by charles f. richter in 1934. the richter scale is a numerical calculation with the number rising with the severity of the tremors.

  • richter scale definition & facts britannica

    richter scale (m l) quantitative measure of an earthquake’s magnitude (size) devised in 1935 by american seismologists charles f. richter and beno gutenberg.the earthquake’s magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.although modern scientific practice has replaced the original richter scale

  • light: 4-4.9 - how earthquakes are measured - pictures

    a light earthquake is measured at between 4 and 4.9 on the richter scale. like minor quakes they occur often worldwide can be felt but generally cause no damage. a 4.5-magnitude earthquake

  • richter scale howstuffworks

    the richter scale is logarithmic meaning that whole-number jumps indicate a tenfold increase.in this the increase is in wave amplitude. that is the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.

  • earthquake glossary

    richter scale. the richter magnitude scale was developed in 1935 by charles f. richter of the california institute of technology as a mathematical device to compare the size of earthquakes. the magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.

  • richter scale & magnitude - sms tsunami warning

    what is the richter scale. the richter magnitude scale (often shortened to richter scale) is the most common standard of measurement for earthquakes. it was invented in 1935 by charles f. richter of the california institute of technology as a mathematical device to compare the size of earthquakes.

  • how are earthquake magnitudes measured

    there are a number of ways to measure the magnitude of an earthquake. the first widely-used method the richter scale was developed by charles f. richter in 1934.it used a formula based on amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.

  • richter magnitude scale - wikipedia

    the so-called richter scale – also richter magnitude or richter magnitude scale more accurately but informally richter's magnitude scale – for measuring the strength ("size") of earthquakes refers to the original "magnitude scale" developed by charles f. richter and presented in his landmark 1935 paper. this was later revised and renamed the local magnitude scale denoted as "ml" or "m l".
