Messenger from the deep: Is beached fish a warning of coming earthquake?

A fish, whose appearance on land is said to be a sign of impending major earthquakes, has washed up in Cagayan de Oro.

The 15-foot-long oarfish was found on the shore of baranguay Gusa yesterday (Saturday, February 18) afternoon.

Another oarfish washed ashore in Agusan del Norte last week, just days before the 6.7 magnitude Surigao City earthquake.

In Japan, the fish are known as ‘The Messenger from the Sea God’s Palace’ and their appearance has long been linked to looming quakes.

In recent history, about 20 of the deep ocean fish were found washed ashore in the days leading up to the 2011 Tohoku earthquake and tsunami that devastated Japan.

While there is no direct scientific evidence to support the idea these fish are sensitive to earthquake activity, it should be remembered that science itself has no way to predict seismic activity. (See link below.)

However, their deep sea habitat, living in close proximity to undersea fault lines does suggest a rational basis for the ancient Japanese myth.

Rachel Grant, a lecturer in animal biology at Anglia Ruskin University in Cambridge, England, has begun a study to test the idea.

“It’s theoretically possible because when an earthquake occurs there can be a build-up of pressure in the rocks which can lead to electrostatic charges that cause electrically-charged ions to be released into the water,” she said.

“This can lead to the formation of hydrogen peroxide, which is a toxic compound. The charged ions can also oxidise organic matter which could either kill the fish or force them to leave the deep ocean and rise to the surface.”

Another possibility, she added, was that prior to a quake there is a release of large quantities of carbon monoxide gas, which could also affect oarfish.

“The geophysical processes behind these kinds of sighting can happen before an earthquake,” she said.

Dr Grant said that she has built up a database of several hundred oarfish sightings over the past two and a half years and will now see if there are links between the sightings and any earthquakes reported by the US Geological Survey within a 500 mile radius.

“We do know that there’s not an earthquake after every oarfish sighting, but we are going to see if there is an increased probability of oarfish being seen prior to an earthquake.

“It may be due to seismic activity or it may be due to other factors unconnected with earthquakes, such as infrasound caused by underwater activities, such as military submarines, or pollution,” she said.

Oarfish are usually found at depths of 1,000 metres and very rarely above 200 metres from the surface. Long and slender with a dorsal fin the length of its body, the oarfish resembles a snake. It is believed that its rare appearances on the surface of the sea gave rise to legends about sea serpents.

    Posible sign ng lindol yun pglabas ng oarfish ganun din sa pagputok ng vulcan me sign din ng mga hayop
    So be ready for the big one anumang oras di ntin alam kung kaylan darating ang lindol…….

    With the amount of seismic activity in and around the Philippines it would be easy to link the two. But i think we would see more fish beached if that was the case.There has just been a small quake in Davao and it would be easy to link the two , imagine if people start to panic every time a fish is seen on the beach.

    I have to admit that animals are more tuned into what happens and what is happening on the planet.Their senses can detect things that we cannot. Where we need extra help in listening for tremors etc , wildlife have the edge by knowing that something will occur.
