WebLike any mechanical wave, seismic waves are vibrations that can be described with quantities such as frequency (the number of vibrations per second), period (the seconds per vibration), and amplitude (the maximum displacement of the particles of the medium). These seismic waves travel for great distances before finally losing most of their ... Web13 de dez. de 2024 · We conduct seismic wave propagation simulations to resolve this apparent discrepancy and to understand the physical properties of Ryugu. We show that surface changes are strongly dependent on a shallow subsurface. Our results suggest that the conversion of impact energy to seismic waves is less efficient than previously thought.
