The document is a guided reading and study workbook section focused on measuring earthquakes and understanding seismic waves. It outlines key concepts such as types of seismic waves (body waves, S waves, surface waves), the use of seismographs and seismograms for recording these waves, and various scales for measuring earthquakes including the Richter scale, moment magnitude scale, and Modified Mercalli scale. The section also includes exercises to reinforce learning about earthquake measurement and location.

How do we measure an earthquake class 8?

The Richter scale measures the intensity or magnitude of an earthquake and represents the intensity with a scale ranging from 1 to 10. The Richter scale uses the value of the amplitude of the highest seismic wave. Seismic waves/activity are detected using a seismograph.

When a seismograph records p-waves but not S-waves from an earthquake, it means that?

If a seismogram records P-waves and surface waves but not S-waves, the seismograph was on the other side of the Earth from the earthquake. The amplitude of the waves can be used to determine the magnitude of the earthquake, which will be discussed in a later section.

How big is a 7.3 earthquake?

(That is, an earthquake measuring 5.0 releases 31 times more energy than an earthquake measuring 4.0.) In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960.

What are the two ways to measure earthquakes?

There are many different ways to measure different aspects of an earthquake: Magnitude is the most common measure of an earthquakes size. Intensity is a measure of the shaking and damage caused by the earthquake; this value changes from location to location.

Does the Richter scale go from 1 to 10?

As more seismograph stations were installed around the world, it became apparent that the method developed by Richter was strictly valid only for certain frequency and distance ranges.

How do p and s reveal both the strength and location of an earthquake?

P-waves are fastest and are the first signal to arrive on a seismogram, followed by the slower S-wave, then the surface waves. The arrival times of the P- and S-waves at different seismometers are used to determine the location of the earthquake.

How do you measure an earthquake?

Earthquake Magnitude Scale MagnitudeEarthquake Effects 5.5 to 6.0 Slight damage to buildings and other structures. 6.1 to 6.9 May cause a lot of damage in very populated areas. 7.0 to 7.9 Major earthquake. Serious damage. 8.0 or greater Great earthquake. Can totally destroy communities near the epicenter.2 more rows
