which statement describes earthquakes?

The _____ magnitude scale is useful for measuring the strength of earthquakes of all sizes and at all distances from a seismograph. - They look at data from at least one seismograph. Answers The answer is option D. water waves. The solid crust and top, stiff layer of the mantle make up a region called the lithosphere. 4. Describe a) the Parkfield Earthquake study (4 points) b) what Have you ever wondered what it would be like to have an Which statement describes the moment magnitude scale? Environmental Studies Class 12 English Medium SEE ALL Advertisement Answer A .gov website belongs to an official government organization in the United States. Richter scale (ML), quantitative measure of an earthquake 's magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. However, the vibrations from an earthquake can still be felt and detected hundreds, or even thousands of miles away from the epicenter. rebecca is likely exp Amount of damage can be used to determine intensity. Depending on their intensity, earthquakes (specifically, the degree to which they cause the grounds surface to shake) can topple buildings and bridges, rupture gas pipelines and other infrastructure, and trigger landslides, tsunamis, and volcanoes. Professor Emeritus of Earth and Planetary Science, University of California, Berkeley. USGS Earthquake Hazards - The Science of Earthquakes, earthquake - Children's Encyclopedia (Ages 8-11), earthquake - Student Encyclopedia (Ages 11 and up), earthquake-damaged neighbourhood of Port-au-Prince, Haiti. a) P waves, b) S waves c) surface waves d) all of these waves arrive at the same time, Which of the following types of waves is a compressional sound wave? (That was the Richter magnitude for the Chile earthquake of 1960. A: It is an outer planet B: it is a terrestrial planet C: it was formed from gas. In California, the collapse of buildings, roads and infrastructure produced eight of the ten costliest earthquakes in the last one hundred years. The violent shaking of the ground produces the greatest property losses and personal injuries. Our editors will review what youve submitted and determine whether to revise the article. It develops in the lithosphere. waves. 1. this earthquake, which was centered about 380 kilometers west-southwest of Mexico City, had a surface-wave magnitude of 8.1. A. Each is valid for a particular frequency range and type of seismic signal. - Earthquakes that cause maximum damage are the most common. If Earth were a perfect sphere, calculations of depth and distances would be easy because we know the equations for those calculations on a sphere. The direction of the water flow in the streams has changed as a result of a change in the slope. How are earthquakes measured? Earthquake A has a Richter magnitude of 7 as compared with earthquake B's 6. Each seismic station in the network measures the movement of the ground at that site. A seismometer records seismic waves as a series of zig-zags. They vibrate at 90 to the wave motion. - They measure the difference between arrival of P waves and S waves. It has a flat graphing surface. (See the table of major earthquakes.). Scientists have measured quakes on Earth's Moon, and see evidence for seismic activity on Mars, Venus and several moons of Jupiter, too! The shortcomings inherent in the original Richter scale spawned the development of improved Richter scales by Richter and Gutenberg. This was a large urn on the outside of which were eight dragon heads facing the eight principal directions of the compass. Nam lacinia pulvinar tortor nec facilisis. The energy released in earthquakes from this belt is about 15 percent of the world total. They measure the difference between arrival of P waves and S waves. It increases in density with depth. 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. Which statement describes earthquakes? which behavioral therapy intervention might be used in a special education classroom for children with attention deficit hyperactivity disorder. It uses a needle on graph paper to measure seismic wave activity. The destructive behavior of great earthquakes in subduction zones, such as in Japan in 2011, depends on details of the earthquake slip. What was the duration of the earthquake? - It increases in magnitude as amount of damage increases. At this early hour, people were beginning to get ready for the day's w, 12201 Sunrise Valley Drive Reston, VA 20192, Earthquake Magnitude, Energy Release, and Shaking Intensity. While every effort has been made to follow citation style rules, there may be some discrepancies. Earthquakes shake California in recent days as officials warn the cost - They map the location of an earthquake's focus. It is located at the point where circles intersect on a map. - This scale rates an earthquake according to how much damage it causes. The result is called the moment magnitude. These new discoveries will help us understand more about how planets like Marsand our home, Earthcame to be. The moment magnitude for this event was measured at 9.5.). happen? Often, several slightly different magnitudes are reported for an earthquake. An earthquakes most intense shaking is often felt near the epicenter. It contains at least three of the Rocks that undergo elastic deformation will a) return to their original shape once the, stress is released b) cause a large magnitude c) undergo permanent deformation d), Energy waves that are released during an earthquake are called a) shock waves b), elastic waves c) stress waves d) seismic waves, Which of the following statements regarding aftershock is TRUE? There are four principal types of elastic waves: two, primary and secondary waves, travel within Earth, whereas the other two, Rayleigh and Love waves, called surface waves, travel along its surface. They start as surface waves. Using the Kelvin-Planck statement of the second law of thermodynamics, demonstrate the following corollaries: (a) The coefficient of performance of an irreversible refrigeration cycle is always less than the coefficient of performance of a reversible refrigeration cycle when both exchange energy by heat transfer with the same two reservoirs. Although modern scientific practice has replaced the original Richter scale with other, more-accurate scales, the Richter scale is still often mentioned erroneously in news reports of earthquake severity as the catch-all name for the logarithmic scale upon which earthquakes are measured. 6 of the Worlds Deadliest Natural Disasters, https://www.britannica.com/science/Richter-scale. An earthquake is an intense shaking of Earths surface. With this network, the United States maintains world leadership in monitoring the greatest natural and technological events that threaten o, Mexico was hit by one of the most devastating earthquakes in its history on September 19, 1985 at 7:18 a.m. MDT time. Earth's crust switches places in a periodic manner. Hence, the correct options are they release energy, they are caused by forces, and they can lead to massive damage. Which statement describes the damage that results from earthquakes? They range from very simple and inexpensive to sophisticated and pricey. Present-day seismographs, however, may be calibrated to compute Richter magnitudes, and modern methods for measuring earthquake magnitude have been developed to produce results that remain consistent with those measured using the Richter scale. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. - It cannot account for fault movement during an earthquake. Earthquakes are caused by shifts in the outer layers of Eartha region called the lithosphere. - It measures only small earthquakes. When an earthquake occurs, one of the first questions is "where was it?" The earthquakes are generally caused when the rocks present underneath gets break abruptly along a fault. Our editors will review what youve submitted and determine whether to revise the article. The magnitude does not depend on where the measurement is made.
