Seaquake Strands 150 Melon-Headed Whales in Japan

April 10, 2015: About 150 melon-headed whales were injured  (barotrauma in their cranial air sinuses) by extreme pressure waves generated during a seaquake on 22 March (see below). Because they use the air in their sinuses and air sacs as an acoustic mirror to bounce, focus, and channel returning echolocation and echonavigation clicks in a fashion to make their biosonar work, a pressure-related tear in the membranes of these air spaces knocks out their navigation.  They simply swam blindly into the sand along a 6 mile stretch of Hokota Beach about 60 miles northeast of Tokyo Japan on Friday morning.

The tell-tale sign that the pod has no sense of direction is found in the words of an AFP journalist at the scene. He wrote that despite efforts to push the dolphins to deep water, they were being washed back onto the beach by the incoming current (link). That they could not swim to freedom against the incoming flow indicates that they are totally lost without their keen acoustic sense. Thier biosonar system was disable by a prior encounter with shocks from an undersea earthquake. Bottom line is the entire pod had been lost at sea since 22 march. They swam downstream in the path of least resistance. The surfaces currents pick the stranding beach, not the whales (link). The short video below illustrates their predicament.





And, as the pictures below reveal, at the time of the rescue attempt, there was a strong wind-driven surface current pushing the surface waters towards the beach along with a rising tide. Trying to release the dolphins against the incoming current was doomed to failed. Trained rescue teams in the US and Australia always wait until the tide reaches its high mark and then starts to flow back out to sea.

Another tell-tale that they have no sense of direction is stranded whales and dolphins never swim away from the beach against the flow of an incoming current. If pushed off when the current is incoming, the freed whales just turn around and come back to the beach.




Professional rescue teams know that freed dolphins will swim away from beach only if released when the outgoing tide and winds establish an outbound flow towards deeper water. Look at the two dolphins above the heads the children on the right. They are swimming freely with the longshore current that runs parallel to the breaking waves in the surf zone; they can swim in no other direct but downstream.

The entire pod was as lost as would be 150 blind men tossed overboard 20 miles offshore. We know if a blind man swam into a flowing current; resistance (drag) to swimming against the flow would turn him around and point him head first in a downstream direction. Going downstream with the current is traveling in the path of least drag--the only way an animal can swim if it has no sense of direction.

Most people have little experience swimming in a current. Swimming against a strong current wearing a blindfold is impossible because water is 800 times more dense than air. This is why many swimmers suffer exhaustion or even a heart attack trying to swim back to shore against the strong outflow of a rip current.

Whale scientists and the rescue teams never mention whether stranded whales were swimming upstream against the flow or downstream with it. And, they never mention the flow of the current. Although they know the truth, they will never reveal how impossible it would be for a whale with dysfunctional biosonar to swim against the flow.

But you can see it. You just need to know a little about how water flows at a beach.

Whale scientists,like in the video above, repeatedly tell you that the main pod follows a sick pod member ashore because they love each other so much. According to whale experts, mass stranded whales will not allow a member of their clan to die alone. This is a big lie. The individuals in the Japan stranding are stretched out over 6 miles of beach. If they followed a sick one, you would expect they'd be bunched together near the ill one. Of course, the scientists that spout this nonsense never identify the sick whale.

Scientists are always trying to cover-up the real cause of mass beachings. For example, Tadasu Yamada, a cetacean expert at the National Museum of Nature and Science, told Japan's NHK public television that the "dolphins may have had a physiological or psychological problem and faced an unknown threat and panicked, before becoming stranded." (Link)

This statement is like wild guess; it has no business coming from a so-called expert. How disgusting and embarrassing for a scientists to spout such utter nonsense on TV. Where is his research? How does one diagnose psychological problems in marine mammals? Can Dr. Yamada read the mind of the dolphins? Of course not.

The obvious truth is that the entire pod has been injured in a fashion that disabled their ability to echonavigate. They are all dehydrated and have no fresh food in their stomachs.

They are all suffering from a navigation failure due to an encounter with a series of potent low frequency compression waves generated either by a seabed earthquake, an explosive volcanic eruption, an underwater explosion, navy sonar, oil industry air-gun array, or a violent impact of a heavenly body with the surface of the sea. (Read about navigation failure in mass stranded whales.)

The problem is that our governments do not want to admit seaquakes are most often responsible because the awareness of seaquake-induced sinus barotrauma would eventually expose barotrauma induced by sonar, air cannons, and explosives. (Read about how whale scientists lie to the public.)

As I mentioned earlier, the key to understanding strandings is the cold hard fact that all mass stranded whales were swimming downstream when they went ashore. Allow me to pound this point home: A blind man can never swim upstream. Neither can an acoustically blind whale. Nor can a dead whale, a dead log, sea weeds, or floating trash. Living or dead doesn't matter; everything without a sense of direction goes downstream. (Read about how surface currents guide stranded whales to sandy beaches.)

Since we can review videos and verify we our own eyes that all mass stranded whales and dolphins swim downstream, we can safely assume that they have no sense of direction. This helps us understand why they beached because all we need to do is trace back upstream and look for what caused the pod to lose their ability to navigate.

To answer this particular stranding, we will be looking in a known habitat for melon-headed whales to see if one of the following has occurred: (a) seabed earthquake, (b) volcanic explosion, (c) man-made explosion, (d) navy sonar operation, (e) oil industry air-gun survey, or (f) a violent impact with the water's surface by a heavenly body.

Undersea earthquakes are the most common ocean disturbance and the first one to eliminate.

It also helps us to know that melon-headed whales like to hang out along the edges of deep drop offs; they also like to visit nearby shallow water. For this reason, many pods of melon-headed whales have been observed offshore of Taiwan and off the Guam Island chain. This means that if there was a whale-dangerous earthquake off Taiwan or Guam, a pod of melon-headed whales might have suffered a pressure-related sinus injury that knocked out their biosonar. They would then beach themselves somewhere downstream of this event.

In the hundreds of mass strandings the Deafwhale Society has traced over the last 40 years; we find the average downstream distance between a seaquake epicenter and the stranding beach is about 2,400 miles. The average time elapsed is 23 days. We think that when first injured, the whales are more mentally alert and able to use their eyesight to avoid shallow water. But after being chased by sharks for 3 weeks with no food or fresh water, they become less aware of what's in front of them and more concerned about the sharks closing in from behind.

As it turns out, the main current flowing along Hokota beach also flows through the waters of Taiwan and Guam. Thus, if there was a nasty seaquake near Guam and the time and distance traveled downstream also agrees with the stranding date, then this event becomes highly suspicious. The key factors to consider is the depth of focus, seismic motion in the seabed, magnitude, the timing of the quake, the flow and speed of the surface currents, the downstream distanced, and the date of the arrival at the stranding beach. This data must all fit together.




Like magic, we find that just such event did occur off Guam 19 days prior to the stranding and about 2,400 miles upstream from the stranding beach. Under ideal conditions, the pod could travel ~125 miles per day so the time and distanced fits with the stranding date. Since Guam is also a known habitat for melon-headed whales, this seaquake seems even more likely to be the cause of the beaching.

The black and white beach balls show that this event was specially dangerous since it was vertical thrusting and likely generated a shock wave that could have easily damaging the cranial air spaces of the entire pod. A thrusting event is one in which the fault slips vertically. The intensity of any shocks are tied to the speed (acceleration) at which the fault ruptures in the vertical plane. The faster the fault slips, the more intense is the shock front.
