Aid was trickling in from the Taliban government and from international NGOs, but the sheer scale of the destruction, affecting six ...The Richter Scale, named after Dr. Charles F. Richter of the California Institute of Technology, is the best known scale for measuring the magnitude of earthquakes. The scale is logarithmic so that a recording of 7, for example, indicates a disturbance with ground motion 10 times as large as a recording of 6.Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 12.13). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.
73-112. Moderate damage. Peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos blown off roads. F2. 113-157. Considerable damage. Roofs torn off frame houses; mobile homes demolished; boxcars overturned; large trees snapped or uprooted; light-object missiles generated; cars lifted off ground. F3.
The scale is logarithmic – that is, the severity of an event is about ten times greater for each increase in level of the scale. Events are considered in terms of: Impact on people and the environment; Impact on radiological barriers and control; Impact on defence in depth; Events without safety significance are rated as Below Scale/Level 0.a. true b. false b. false A surface along which rock on opposed sides is offset by earthquake-induced slip is called a ____________. a. joint b. fault c. fold d. wall b. fault At any point along the surface of an oblique (nonvertical) fault, the ____________. a.The moment magnitude scale measures more of the ground movements produced by an earthquake and is especially useful for large scale earthquakes. Modified ...An earthquake of magnitude 4.3 on the Richter scale jolted Myanmar on Monday morning, the National Center for Seismology (NCS) said. According to the NCS, …The Modified Mercalli Intensity (MMI) Scale is a qualitative ranking system that describes the severity of shaking in specific locations during an earthquake. The scale is composed of increasing levels of intensity that range from imperceptible shaking to catastrophic destruction. Each ranking is assigned a Roman numeral from 1 to 10 (I-X). The moment-magnitude scale is logarithmic, so an increase of one unit means an earthquake is 10 times bigger, with about 30 times the energy produced. Small earthquakes have about the same value on the Richter scale and the moment magnitude scale, so Richter is fine for those. 2010 Haiti earthquake, large-scale earthquake that occurred January 12, 2010, on the West Indian island of Hispaniola, comprising the countries of Haiti and the Dominican Republic. Most severely affected was Haiti, occupying the western third of the island. An exact death toll proved elusive in the ensuing chaos.
