Quick Scenario Presets

Hypothesis Mechanism Model

Ocean Standing Waves (Bight of Bonny) Opposing ocean swell interference creates ocean floor acoustic standing wave pressure at double frequency (26s).

Volcanic Magma Chamber Oscillation Undersea volcanic pressure releases resonance tuned to crustal magma chamber geometry.

Ocean Swell Period ($T$) 26.0 s

Water Depth ($h$) 2.8 km

Storm Swell Amplitude 4.2 m

Crustal Shear Velocity ($V_s$) 3.50 km/s

Rayleigh Mechanics Note

Rayleigh surface waves travel along Earth's crust with retrograde elliptical particle motion. Near the surface, crustal particles roll backward relative to wave propagation direction, converting ocean seabed pressure into continuous global microseisms.
