Which scale measures the amount of damage after an earthquake.

11.3 Measuring Earthquakes. There are two main ways to measure earthquakes. The first of these is an estimate of the energy released, and the value is referred to as magnitude. This is the number that is typically used by the press when a big earthquake happens. It is often referred to as “Richter magnitude,” but that is a misnomer, and it ...A considerable number of macroseismic scales have been developed over the last 200 years in order to try and semi-quantify and describe the effects of an earthquake via a measure of intensity (Musson, 2002; Musson et al., 2009).The first such scale was considered to have been developed by the Italian Jacopo Gastaldi in 1564 (Hao et al., …Study with Quizlet and memorize flashcards containing terms like Modern seismographs rely on _____ to record the ground motion from an earthquake., The Modified Mercalli Intensity Scale is used to measure _____., Part A: Which of the following best describes how scientists help the public prepare for an earthquake event? B: Imagine an earthquake …The strength of an earthquake is measured on the Richter scale. The Richter scale is logarithmic, meaning that if the earthquake's strength increases by 1 on the Richter scale, it is 10 times more ...

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.

2.1.2 Fragility model. The fragility model developed by Raschke describes the probability of observing a particular damage grade in the EMS-98 scale (Grünthal 1998) as a function of EMS-98 macroseismic intensity, I, and a vulnerability index, C.The vulnerability index depends mainly on the vulnerability class but can be refined according to other …

Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. Intensity scales date from the late 19th and ...Focus and Epicenter. The focus, also called a hypocenter of an earthquake, is the point of initial breaking or rupturing where the displacement of rocks occurs. The focus is always at some depth below …Minson and colleagues confirmed this hypothesis after examining three data sets of earthquakes from across the globe, ranging from magnitude 0.5 to 8.3. Ambitious little earthquakes may cause difficulty for some earthquake early warning systems, which alert users to potential damaging shaking after an earthquake begins, the researchers write.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.Measures the amount of damage from an earthquake. Modified mercalli scale Accounts for the magnitude, size of the fault rupture, amount of movement along the fault and the rocks stiffness.

The location where an earthquake begins is called the epicenter. An earthquake’s most …This scale, composed of increasing levels of intensity that range from imperceptible shaking to catastrophic destruction, is designated by Roman numerals. It does not have a mathematical basis; instead it is an arbitrary ranking based on observed effects. The Modified Mercalli Intensity value assigned to a specific site after an earthquake is a …

Terms in this set (38) How much a certain area was shaken when the earthquake reached that area. Intensity. Describes the total amount of energy that was released by the earthquake at the focus. Magnitude. The amount of shaking is usually_____ when an area is near the _______ and becomes_______ when further away. Stronger, epicenter, weaker.Using the Richter scale, a high magnitude may not necessarily reflect the amount of damage caused. The moment magnitude scale is the current method of measuring earthquake magnitudes. This method measures the total energy released by an earthquake and so more accurately reflects its magnitude.

Mercalli intensity scale: In order to better understand the long term behavior of a given fault it is necessary to go back to written records of earthquakes that occurred before seismic recording began. An intensity of I (not felt) to XII (total damage) is designated according to the amount of damage cited in historic records.The Modified Mercalli Scale (1931) of earthquake damage measures the intensity of an earthquake at a particular place. It uses the type and amount of damage. Unlike the Richter Scale, it does not measure the absolute strength of the earthquake but how strongly it is felt at a particular place. This makes the Mercalli Scale useful in comparing …How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.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.Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area.

Intensity …

The failures at Seward, Alaska, during the 1964 earthquake are an example. The size of the area affected by earthquake-induced landslides depends on the magnitude of the earthquake, its focal depth, the topography and geologic conditions near the causative fault, and the amplitude, frequency composition, and duration of ground shaking.
