New technologies that detect motion in the Earth's crust are emerging in surprising places and reshaping our understanding of earthquakes.The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". [3]

It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like. The magnitude takes the motion observed at a recording station (amplitude of the earth's motion), and adjusts for the distance to the focus (computed from the time differential between the arrival of the P waves ...

When an earthquake occurs, much of the available local energy is used to power the earthquake fracture growth, producing heat rather than generating seismic waves which radiate outward and are detected by seismographs. The seismic moment is a measure of the total amount of energy that is transformed during an earthquake.It measures the energy released during an earthquake by analyzing the amplitude of seismic waves recorded on seismographs. The Richter scale is logarithmic, meaning that each whole number increase on the scale corresponds to a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released.

Check your chimney or roof for loose tiles and bricks that could fall in an earthquake. Repair loose tiles or bricks, as needed. Protect yourself from falling chimney bricks that might penetrate the roof, by reinforcing the ceiling immediately surrounding the chimney with 3/4-inch plywood nailed to ceiling joists.Quakes measuring around 7 or 8 on the Richter scale can be devastating. Learn more about Shape of Earth here in detail. Causes of Earthquake. Earthquakes are caused by sudden tectonic movements in the Earth’s crust. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes.Measuring earthquakes. Seismometers are the instruments that are used to measure the motion of the ground, which includes those seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources.

So how do they measure an earthquake? They use the seismogram recordings made on the seismographs at the surface of the earth to determine how large the earthquake was (figure 5). A short wiggly line that doesn’t wiggle very much means a small earthquake, and a long wiggly line that wiggles a lot means a large earthquake.Measures the total energy released by an earthquake. Moment magnitude is calculated from the area of the fault that is ruptured and the distance the ground moved along the fault. The Richter scale and the moment magnitude scale are logarithmic. The amplitude of the largest wave increases ten times from one integer to the next.It is a quantitative measure of the actual size of the earthquake. It is a qualitative measure of the actual shaking at a location during an earthquake. Normal numbers are used to determine the magnitude of earthquake. Intensity is assigned as Roman Capital Numerals. The Richter Scale (called Local Magnitude scale) is used to measure the magnitude. Preventive Measures For Earthquake. Seismometer.
