Influence of vibrations on structures [PDF]
, 2018 One type of occasional structural load is a seismic load. Earthquakes and blasts are typical sources of vibrations, but vibration generated during urban tunnel construction can represent a significant problem.

Proceedings of the Japan Academy, Series B, 2017 The ambient seismic wave field, also known as ambient noise, is excited by oceanic gravity waves primarily. This can be categorized as seismic hum (1-20 mHz), primary microseisms (0.02-0.1 Hz), and secondary microseisms (0.1-1 Hz). Below 20 mHz, pressure fluctuations of ocean infragravity waves reach the abyssal floor.

Study of Polarized Wave with a Hydrodynamic Model and Fourier Spectral Method
Modelling and Simulation in Engineering, 2013 The polarization effects in hydrodynamics are studied. Hydrodynamic equation for the nonlinear wave is used along with the polarized nonlinear waves and seismic waves act as initial waves.

, 1939 The thesis consists of two parts. The first part deals with the historical development of the science of seismology and the application of the mathematical theory of elasticity to that subject. In the beginning m brief sketch of the method of determining the velocity of body waves at various depths inside the earth is given and the major ...

Cosmic signatures in earth's seismic tremor?
, 2016 Even in absence of earthquakes, each site on earth experiences continuous elastic vibrations which are mostly traced to the non-linear interactions of sea waves.
