What is the scale that measures the magnitude of an earthquake?

What is the scale that measures the magnitude of an earthquake?

The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

Which statements describe the focus of an earthquake check all that apply?

The statements that describe the focus of an earthquake are the following: it develops in the lithosphere, it is the starting point of an earthquake, it begins about 100 kilometers below earth’s surface. Many spots on earth are prone to earthquakes and major risks for people living in these regions.

Which factor does the moment magnitude scale estimate quizlet?

– This scale measures the magnitude of an earthquake based on the size of seismic waves. This scale rates an earthquake according to how much damage it causes.

Which factors does the moment magnitude scale estimate?

Moment magnitude measures the size of events in terms of how much energy is released. Specifically, moment magnitude relates to the amount of movement by rock (i.e. the distance of movement along a fault or fracture) and the area of the fault or fracture surface.

How are S waves and surface waves similar?

Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface. Surface waves travel only through solid media. This motion is similar to that observed in ocean waves.

Which strategy do geologists use?

Answer: Geologists use seismic waves to locate the center of an earthquake.

Which statement best describes a surface wave?

Which statement describes a surface wave? A surface wave is a wave that moves along the interface of two different materials, like air and water.

What describes a surface wave?

In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Elastic surface waves can travel along the surface of solids, such as Rayleigh or Love waves.

Which explanation best describes the development of a wave?

Answer: The development of a wave is the friction between the moving air and the underlying water imparts energy, which causes the water to move in a circular motion, but the energy moves great distances. Explanation: Wave is a disturbance that travels through a medium.

Which type of radiation has the most energy?

Gamma rays

Which type of radiation is the easiest to block?

alpha particles

Which type of radiation is least penetrating?

alpha

What is the scale that measures the magnitude of an earthquake?

The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.

What is seismograph How is the magnitude of earthquake measured?

The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes.

What does the Richter scale go to?

Numbers for the Richter scale range from 0 to 9, though no real upper limit exists. An earthquake whose magnitude is greater than 4.5 on this scale can cause damage to buildings and other structures; severe earthquakes have magnitudes greater than 7.

What is the characteristics of body waves?

A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth’s surface. P and S waves are body waves. Each type of wave shakes the ground in different ways.

What are the examples of primary waves?

P and S waves travel through the planet Earth after an earthquake. Scientists studying the waves produced by earthquakes learned that Earth’s core has separate liquid and solid layers. S waves do not travel through liquid, but P waves do.

What is the most accurate description of primary wave?

P-wave is transmitted by particle movement back and forth along the direction of propagation of the wave. The most correct description of P-waves is it is a dilational or irrotational waves. P-waves has the greatest speed and appears first on seismograms. S-Waves (S stands for secondary or shear or shake).

Which set of waves are P waves?

A P wave, or compressional wave, is a seismic body wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving.

How do S waves affect buildings?

They shake the ground back and forth – like a Slinky – in their travel direction, but do little damage as they only move buildings up and down. S-waves lag behind P-waves as they travel 1.7 times slower and can only pass through solid rock.

How will you describe the P and S waves motion?

P-wave:the primary body wave; the first seismic wave detected by seismographs; able to move through both liquid and solid rock. S Wave—secondary body waves that oscillate the ground perpendicular to the direction of wave travel. S waves produce vertical and horizontal motion in the ground surface.
