# A theory of the origin of microseisms

@article{LonguetHiggins1950ATO, title={A theory of the origin of microseisms}, author={Michael Selwyn Longuet-Higgins}, journal={Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences}, year={1950}, volume={243}, pages={1 - 35} }

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…

The origin of microseisms

- Geology
- 1960

In 1944 Miche developed a theory to explain the production of a bottom pressure due to standing waves on the surface of the sea, and in 1950 Longuit-Higgins accounted for microseisms by widespread…

A statistical analysis of the generation of microseisms

- Geology
- 1963

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

- Physics

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

- Geology

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

- GeologyProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2008

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

- Physics

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

- Geology
- 1965

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…

Random Atmospheric Pressure at the Free Surface and Microseisms in Deep Ocean

- Mathematics
- 2008

A general stochastic model of the atmospheric pressure at the ocean surface was proposed, in which the pressure variation was represented by a spectral decomposition through a random process of…

Effect of a submerged plate on the near-bed dynamics underincoming waves in deep water conditions

- Physics
- 2015

Abstract It is well known that wave induced bottom oscillations become more and more negligible when the water depth exceeds half the wavelength of the surface gravity wave. However, it was…

IT is well known1 that the pressure variations beneath a progressive gravity wave of Stokes's type are insufficient, in deep water, to generate microseisms of the observed magnitude. This is because…

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…
