Moment magnitude is the most reliable estimate of earthquake size. The effect of an earthquake on Earth's surface — the intensity — is evaluated with the Modified Mercalli (MM) Intensity Scale .Mar 25, 2023 · On Earthquake Magnitudes. The earthquake magnitude quantifies the size or scale of an earthquake, which is generally related to the energy released. The concept …An estimate of body-wave (mb) magnitude based on the size of the area over which the earthquake was felt, typically assigned to widely felt earthquakes that occurred before …Magnitude is an estimate of the relative "size" or strength of an earthquake, and thus its potential for causing ground-shaking. It is "approximately related to the released seismic energy." [1] Intensity refers to the strength or force of shaking at a given location, and can be related to the peak ground velocity.ISLETON, Sacramento County -- A magnitude 4.1 earthquake struck near the community of Isleton in the Sacramento-San Joaquin Delta on Wednesday morning.

A powerful earthquake has struck the Caribbean nation of Haiti, killing at least 304 people and injuring more than 1,800.By the same token, you can easily compare the energy release. (“seismic moment”) of different magnitude earthquakes: A quick method (pre electronic calculators) ...So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts.Other articles where earthquake magnitude is discussed: earthquake: Earthquake magnitude: Earthquake magnitude is a measure of the “size,” or amplitude, of the …Today's Biggest Earthquakes All recent earthquakes ».
