The Richter Scale is the established scale for earthquakes based on size and power.When you see that an earthquake is a magnitude 5.2 it means that it is a 5.2 on the Richter scale.For every increase of one on the Richter scale, an earthquake's power is magnified tenfold. So, a magnitude 4 is ten times stronger than a magnitude 3 earthquake.Anything over a magnitude 5 is a really big earthquake.
The moment magnitude scale is more accurate for large earthquake than can cause damage.
Not all earthquakes that ever happened have been recorded. We've only recorded them for a little over a century, I believe. So you can't tell for certain. But the biggest earthquake on record is the Valdivia earthquake, from 1960. It measured 9.5 on the Richter scale. (a scale ranging from 1-10)The highest magnitude earthquake occurred in Chile in 1960 with a scale of 9.5.
Bear in mind that it is not just the Richter scale measurement which determines the severity of a tsunami which results from an earthquake; the location of the earthquake is also relevant. And inland earthquake does not produce the same tsunami as an underwater earthquake. That said, 8.3 is an extremely powerful earthquake which could produce a tsunami that would travel for thousands of miles and cause immense dammage over a very wide area.
Australia does not have many major earthquakes, but it has dozen of minor earthquakes every year which are not felt by the average person because they occur so far underground.Times and places where significant earthquakes have occurred in Australia are few, but they include:An earthquake measuring 7.2 on the Richter scale hit Meeberrie, Western Australia, on 29 April 1941. It left massive cracks in all the walls of Meeberrie homestead.On 14 October 1968, the town of Meckering, Western Australia, was hit by an earthquake which registered 6.9 on the Richter scale. No-one was killed, but an estimated $2.2 million worth of damage was caused, and 17 people injured.On 22 January 1988, three large earthquakes were felt in Tennant Creek, in the Northern Territory. The smallest occurred at 10:06am and registered 6.3 on the Richter Scale, whilst the largest occurred at 9:35pm, registering 6.7.Australia's worst earthquake disaster occurred on 28 December 1989 in Newcastle, NSW, when an earthquake measuring 5.6 on the Richter scale hit, causing massive damage and thirteen deaths.
it depends on which part of sanfrancisco you are talking about. but all over sanfrancisco the shakes would measure between 6.5 and 7.8 on the Richter scale.

The Richter Scale is a scale that measures earthquakes. basicallly it is a plum bob suspended over a piece of paper. when the earth shakes it causes the plum to swing, or the paper to move under the plum. the further the plum moves from center is the measurement. a measurement of 1 on the richter scale is a slight tremor, a 5 or 6 being a large earthquake.
The absolute magnitude of a quake is conventionally reported by numbers on the Moment magnitude scale (formerly Richter scale, magnitude 7 causing serious damage over large areas), whereas the felt magnitude is reported using the modified Mercalli intensity scale (intensity II-XII).
Richter scales are useful to measure only small, shallow earthquakes recorded within a certain distance from the epicenter. A moment magnitude scale is more precise than a Richter scale. It also gives a measure of the energy released during an earthquake.

Richter scale is a scale which shows the magnitude of a earthquake. magnitude below than 4.0 does not cause much damage , magnitude below 2.0 ussually are not felt, magnitude over 5.0 cause damage, 6.0 is considered strong, and 7.0 is a major earthquake.
It can be used to calculate the magnitude of Earthquakes that are too large for the Richter scale (any Earthquake with a magnitude over 6.9 is un-suited for measurement using the Richter scale, hence the introduction of the moment magnitude scale for large earthquakes). For more information about the two scales, please see the related questions.

It had a magnitude of 7.0, very high on the Richter scale. There has been a report that over 200,000 lives may have been lost. It was very devastating.
An increase of magnitude 1 on the Richter scale represents a tenfold increase in the amplitude of seismic waves and approximately 31 times more energy released. It indicates a significantly stronger earthquake that can cause more damage and be felt over a wider area.
