Earthquakes with a magnitude greater than or equal to 6 are termed strong earthquakes. 7 or larger are termed major earthquakes. Earthquakes greater than or equal to 8 are termed great earthquakes.
The term "large" is not actually used.However based on the above it could be argued that any earthquake with a magnitude greater than 6 is a large earthquake.
The Richter or local magnitude scale of the Haitian earthquake has been reported as 7.2. and the Moment magnitude as 7.0 (according to the U.S. Geological Survey, National Earthquake Information Center).Please see the related questions for further information about the Haitian earthquake and it's magnitude and severity.7.0 magnitutes
Earthquake magnitudes are rated using the moment magnitude scale. Moderate and small earthquakes (those with a magnitude below 7) are also measured using the Richter scale. Please see the related question for more information.
According to the US Geological Survey, the Chilean earthquake was rated at 8.8 on the moment magnitude scale. That makes it several hundreds times more powerful than the Haiti quake. Please see the related questions for further information.
The largest earthquake in the world was the 1960 Voldivic earthquake. It was the most powerful earthquake ever recorded. It rated 9.5 on the magnitude scale. It occurred in the afternoon.
Between 6.8 and 6.9 Mw
False. The magnitude of earthquakes is rated on the Richter scale, not the vibration caused by the earthquake. The Richter scale measures the energy released by an earthquake at its source.
The Valdivia earthquake of 1960 is the strongest earthquake ever recorded, with a magnitude of 9.5. It occurred in southern Chile on May 22, 1960, causing widespread destruction and triggering tsunamis that affected coastal areas as far away as Hawaii and Japan. The earthquake resulted in thousands of fatalities and left a lasting impact on the region.
The earthquake that struck Haiti on January 12, 2010 had a magnitude of 7.0. It caused widespread devastation and loss of life, with estimates of over 200,000 people killed and many more injured. The intensity of the shaking was rated as "violent" on the Mercalli intensity scale in the most affected areas.
The most recent Chilean earthquake mainshock occurred on the 27th of February 2010 and according to the US Geological Survey, rated at 8.8 on the moment magnitude scale. Chile has also suffered earthquakes in the past, including the largest earthquake ever recorded by seismometer which occurred on the 22nd of May, 1960 and had a magnitude of 9.5.
An earthquake rated 2 on the Richter scale is considered a micro earthquake, which is typically not felt by people and usually does not cause any damage. These low-magnitude earthquakes are often only detected by seismographs. While they can occur frequently in some areas, they generally have little to no impact on daily life.
The earthquake in Japan was a 9.0 magnitude earthquake. (After the quake hit, seismologists ranked it from an 8.9 to a 9.0.) The tsunami's height was recorded to be about 33 feet. Many counts say that the number is much higher, even as high as a 3-4 story building.
An earthquake that was rated 3 on the Richter scale would beignored
