The Richter scale.
The Moment Magnitude Scale (Mw) was developed by the seismologists Hanks and Kanamori during the 70's and their work was published in the Journal of Geophysical Research in 1979.
Tornado Activity is monitored by the National Weather Service.
Both the Richter scale and the moment magnitude scale are commonly used to measure the magnitude of earthquakes. However, the moment magnitude scale is preferred by seismologists for measuring larger earthquakes because it provides a more accurate representation of the energy released during an earthquake.
The Richter scale was originally developed to measure the strength or magnitude of moderate earthquakes (magnitudes less than 7). The surface wave magnitude scale was then developed by Richter and Guttenburg to allow larger earthquake magnitudes to be measured (up to 8). To measure large earthquakes the moment magnitude scale must be used. To measure the severity of earthquakes, the Modified Mercalli intensity scale is used in the US and the Macroseismic scale is used in Europe.
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.
the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
The Moment Magnitude Scale (Mw) was developed by the seismologists Hanks and Kanamori during the 70's and their work was published in the Journal of Geophysical Research in 1979.
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
Seismologists and researchers primarily use the Richter scale to measure the magnitude of earthquakes. Emergency response teams and disaster management agencies also rely on this scale to assess the impact of earthquakes and coordinate relief efforts.
The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
Mars has evidence of past tectonic activity, such as fault lines and large-scale volcanic features. This suggests that tectonic plate motion may have occurred on Mars in the past.

Yes, but it is not the most accurate as the spring activity can vary with temperature as well as with age.

Seismometers are used to measure earthquakes waves, this help show the different arrival time between waves. A Richter Scale is used to measure earthquakes strengh, each number is 31 times more powerful than the last. There is no official set number, but no earthquake has hit 10 on the scale.
There is local tectonic activity but the surface appears to be a single crustal plate, with little large-scale horizontal motion of plates as found on the Earth.
