In the past it has been considered unlikely that ocean waves are capable of generating microseismic oscillations of the sea bed over areas of deep water, since the decrease of the pressure variations with depth is exponential, according to the first-order theory generally used. However, it was recently shown by Miche that in the second approximation to the standing wave there is a second-order pressure variation which is not attenuated with depth and which must therefore ultimately predominate…

A statistical analysis of the generation of microseisms

Theories of the origin of microseisms have in the past generally been expressed in terms of the Green functions of the elastic systems considered. An alternative approach based on spectral transfer

On the possible generation of low-frequency microseisms by internal waves in the ocean

The conditions under which the interaction between internal waves and the rough bottom topography may be the reason for synchronous fluctuations of pressure at the bottom have been studied.

A Study of Primary and Secondary Microseisms recorded in Anglesey

Summary The paper describes a theoretical investigation of the generation of primary microseisms which have the same period as the generating sea waves and secondary microseisms which have half

The origin of deep ocean microseisms in the North Atlantic Ocean

Oceanic microseisms are small oscillations of the ground, in the frequency range of 0.05–0.3 Hz, associated with the occurrence of energetic ocean waves of half the corresponding frequency. In 1950,

An experimental study of the pressure variations in standing water waves

Although the first-order pressure variations in surface waves on water are known to decrease exponentially downwards, it has recently been shown theoretically that in a standing wave there should be

Excitation of microseisms: views from the normal-mode approach

SUMMARY Non-linear interaction of ocean waves is a widely accepted mechanism of microseism excitation for frequencies approximately between 0.05 and 0.5Hz. Longuet-Higgins published the most

Origin and properties of microseisms from the standpoint of oscillator theory

Abstract The generally large source area for seawave generated microseisms does not readily allow consideration of these events as unidirectional. Rather, these wave patterns must be due to a

Refraction of Microseisms approaching Cochin

FOR the proper interpretation of microseisms at a particular station it is essential to know the variation in velocity of seismic waves as they approach the station. This variation in velocity or the




Introduction.-During the last few years much attention has been devoted to the theory of microseisms. In our opinion it has been demonstrated that these disturbances are earth waves proceeding from

The assumption that the compressional waves of earthquakes follow the ordinary laws of refraction, the energy within any pencil of rays remaining permanently within that pencil, has been found to

Microseisms Associated with Disturbed Weather in the Indian Seas

Seismologists have often noted the appearance of pronounced microseisms in seismic records when the weather has been disturbed over a neighbouring sea. For instance, the late Dr. KLOTZ suggested a

The paper treats of the propagation of vibrations over the surface of a “semi-infinite” isotropic elastic solid, i. e., a solid bounded only by a plane. For purposes of description, this plane may be

Relations between Sea Waves and Microseisms

ONE of the possibilities suggested by Admiralty research on waves and swell during the past two years is that of obtaining information about the wind and waves in a distant storm area by examining

A theory of microseisms with geologic applications

A theory for the origin of microseisms based on the normal mode propagation of sound in two layers is given. It explains the mechanism of transmission of seismic energy from a storm at sea and
