WebAs the waves pass from deeper harder to shallow softer rocks they slow down and get bigger in amplitude as the energy piles up. The softer the rock or soil under a site is, the larger the wave. Softer soils amplify ground …
Earthquake Magnitude, Energy Release, and Shaking Intensity
WebThe pattern and amplitude of seismic waves and the intensity of shaking at a site depend on the characteristics of the earthquake and the geologic materials through which the seismic waves must pass from the fault to the site. A new 3-D ... For past earthquakes, seismologists construct slip models based on the recorded ground motions and ... WebJul 22, 2024 · Seismographic networks measure earthquakes by their magnitude, energy release and intensity. Years ago, all magnitude scales were based on the recorded waveform lengths or the length of a seismic … masha and the bear birthday theme
Types of Earthquake Waves: P Waves, S Waves, L Waves …
WebIntensity is inversely proportional to the square of the distance of source of wave, it is described by the following formula, Intensity, I = 1 r 2 Here, r is the distance of source of wave. Calculation: The intensities are determined at both points by using the above formula, Intensity at point 1, I 1 = 1 r 1 2 Intensity at point 2, I 2 = 1 r 2 2 WebWhat is the ratio of the intensities of an earthquake P wave passing through the Earth and detected at two points 15 km and 44 km from the source? Express your answer using two significant figures. I44km/I15km = Submit My Answers Give Up Part B What is the ratio of the amplitudes? Express your answer using two significant figures.
