True or false the vibration caused by an earthquake are rated on the Richter scale?

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.

How high was Japan's earthquake rated on the Richter scale?

An earthquake rated 2 on the Richter scale would be .?

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.


How many times greater in strength is an earthquake rated 4 on the Richter Scale tha an earthquake rated 2?

Each number on the Richter scale is TEN TIMES stronger than the lower number. Therefore - in this case, a strength 4 quake is 100 times stronger than a strength 2.


What was the Haitian earthquake of January 2010 rated on the Richter scale and Moment magnitude scale?

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


What was the Richter scale for the Kobe earthquake?

The Kobe earthquake in 1995 had a magnitude of 6.9 on the Richter scale. It caused widespread devastation in the region, resulting in thousands of deaths and significant damage to buildings and infrastructure.


What did Hurricane Isaac reach on the Richter scale?

Hurricanes are not rated on the Richter scale; earthquakes are. Hurricane Isaac was rated a category 1 on the Saffir-Simpson scale.


What system do seismologists use today for rating the magnitude of an earthquake?

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.


Why has there been no earthquakes higher than 8.9?

Two earthquakes higher than 8.9 on the Richter scale have been recorded. They are the Anchorage, Alaska, earthquake of 1964 which was rated as 9.2 and the Valdivia, Chile, earthquake of 1960 at 9.5.


How does the Richter scale best demonstrate the power and the destructive nature of an earthquake?

The Richter scale is used to rate the magnitude of an earthquake -- the amount of energy it released. This is calculated using information gathered by a seismograph.Richter ratings only give you a rough idea of the actual impact of an earthquake, though. As we've seen, an earthquake's destructive power varies depending on the composition of the ground in an area and the design and placement of man-made structures. The extent of damage is rated on the Mercalli scale. Mercalli ratings, which are given as Roman numerals, are based on largely subjective interpretations


At hurricane Katrina what was the number on the Richter scale or the Simpson scale?

Hurricane Katrina was a Category 5 hurricane when it made landfall in the United States on August 29, 2005. The Saffir-Simpson Hurricane Wind Scale is used to categorize hurricanes based on their sustained wind speeds, not the Richter scale which measures earthquake magnitudes.
