On page 36 of his book on sound imaging in the ocean, German underwater acoustic Professor Peter Willie, the former head of NATO's Undersea Research Center, displays three similar sonograms and compares the noise generated by undersea earthquakes and volcanic explosions with that of submarine nuclear explosions of several thousand tons of TNT-equivalent (ref #1). 

Professor Willie says earthquake sounds are the loudest underwater sounds ever produced. He also cautions that we should be aware of the underwater rumbling of "about 7,000 outstanding, dramatic geodynamic earthquake events per year worldwide, each of a thousand tons of TNT-equivalent and more." 

He ought to know because it's his job to determine the acoustic differences between underwater nuclear explosions and natural catastrophic events such as earthquakes. Professor Willie also expresses a belief that evolution has somehow intervened to protect whales from undersea earthquakes. I agree. Whales can indeed detect precursor signals; however, not all earthquakes release detectable precursors.

Now watch the SHOCKING VIDEO below and decide if Professor Willie is telling the truth. You will first hear the roar of an earthquake that has traveled 900 miles in the solid seabed as seismic P-waves, and then entered the water below the hydrophone as a series of acoustic pressure waves. In the shocking last part, you will hear the God-awesome irritating noise of seaquake waves that have traveled in the water for 900 miles before over-modulating the hydrophone. If you know any whale scientists, suggest they also watch this video and explain to you why diving whales would not be injured by such a God-awesome disturbance in their backyard.

The truth is simple! Undersea earthquakes (aka: seaquakes) have been causing whales to strand for millions of years, but whale scientists sponsored by the US Navy pretend not to believe these events are dangerous. They say seaquakes do not generate dangerous underwater pressure disturbances capable of causing sinus barotrauma in whales.

To prove otherwise, the Deafwhale Society has been searching old newspaper archives to find eyewitness that were aboard ships at sea when a seaquake struck. Read these pages and make up your own mind. Do the eyewitness accounts convince you that a shock and/or violent disturbance in pressure has occurred that might injure a pod of diving whales?

In 1958, an earthquake occurred off Cape Minccino at a time when hydrophones from a surface vessel in 1,300 fathoms of water off Juan de Fuca Strait, 575 miles northwest of Cape Mendocino, were recording underwater signals.

The scientists were trying to detect noise from two nuclear explosions set off in the Marshall Islands. They picked up three different low frequency acoustic signals with nearly identical peak energies at frequencies less than 20 hertz. Two of them were nuclear explosions; the third was the earthquake near Cape Mendocino (ref.2).

The scientists on board the recording vessel stated that the coupling of the nuclear explosions to the water path apparently was similar in nature to that of the hydroacoustic vibrations from the earthquake, "but the duration of the signals from the nuclear explosions was considerably less." They stated that a possible means of differentiating between a nuclear explosion and an earthquake was in the much longer duration of the earthquake vibrations. The signal from the nuclear explosion had a duration of about 5 seconds, as compared to 30 seconds for the quake. Moreover, one could describe the shorter duration signal as having symmetry in time about its peak amplitude, whereas the quake's signal built rapidly up to its peak amplitude and decayed slowly." As far as earthquakes, this article they are just as dangerous as nuclear explosions, maybe even more dangerous due to the longer time factor.

Now for the shocking part: The quake recorded was only 4.9 magnitude

Whale-dangerous undersea earthquakes are not Top Secret. I would highly recommend that those interested in the solution to why whales mass strand use "seaquake" as a keyword and search Google Books. They will find over 500 publications that discuss these intense pressure changes (Link).

These intense pressure disturbances are also called T waves or T Phase waves. T waves (seaquakes) are low frequency acoustic pressure changes that travel great distances from their source. There are millions of publications (Link) listed on Google Search that discussed the production of T-Phase Waves by submarine earthquakes.

Mark Leonard, a geophysicist at Geo-science Australia, revealed how a series of intense oscillations in ambient pressure (t-waves) traveled underwater 1,800 km across the Tasman Sea and struck the Australian Coast and woke up hundreds of people near Sydney (ref 3). Wow... it's hard to believe that earthquake pressure waves can travel underwater for 1800 km and arrive at Sydney with enough power to shake the continent so hard to wake people out of a deep sleep. I guarantee, if there had been a pod of whales on a feeding dive when the t-waves crossed the Tasman Sea, New Zealand would have witnessed another mass beaching.
We are also starting to compile a list of whale strandings from the 1750's forward. We will compare this list against our list of ship encounters from the 1750's forward.  We have barely started and already have a few examples of stranding from over a hundred years with violent seafloor disturbances. (ref 4)

Pod strandings are understandable simply because the pressure jump behind the front of seismic sea waves can attain 1.5 MPa, or 15 atmospheres above ambient. The average frequency of these pressure changes is ~3 hertz. The vertical component of the seafloor-displacement velocity is estimated at about 10-100 cm/s, the accelerations of floor motions can amount to about 10 m/s² and the area of dangerous oscillations at ~3 hertz might attain 100 square km (ref 5).
