The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy: WebNov 7, 2024 · Melt blowing (MB) is a process for producing microfiber or nanofiber using high-velocity air to attenuate the polymer jet.
