Thanks for posting. Here's a small article about it as well - I was trying to find out how they were going to deal with the carcasses. Burial as usual, apparently.

The article mentions manmade noise as a possiblity but never substantiates that the noises were being made. I hate it when something is suggested without backing up the suggestion with some kind of information. It just does not help to solve a problem my making conjecture.

David Williams posted this response to MARMAM.

In reference to the 10 December rare stranding of 7 sperm whales on the Italian Coast:

The most likely cause of this event was an 5.9 magnitude shallowed-focused undersea earthquake that occurred on 5 November 2009 just offshore of Zakinthos Island. The event was epicenter about 500 miles from the stranding site.
(see earthquake report below)

You can also get more info on this event from:
http://www.emsc-csem.org/index.php?page=current&sub=detail&id=144865#

Likely Scenario:

The pod was on a feeding when the seafloor below suddenly erupted violently. There was no warning. The rocky bottom started dancing up and down rapidly, generating a series of pressure changes that sweep over the whales. The air contained in the head sinuses of the whales expanded and contracted in unison with the sudden changes in ambient pressure in the water. Several of the sinuses that play a major role in echo-navigation and echo-location rupthured. The pod returned to the surface but could not longer dive and feed itself. Nor could the pod echo-locate or determine direction. The pod was LOST. They traveling with the flow of the current into the Adriactic Sea and swim aimlessly around. Eventually they got to weak to avoid a stranding and where carried ashore by surface currents.

This is truly a rare opportunity to understand the mystery of why whales mass strand. It is highly likely that these stranded whales can be photo identified since the population offshore of Zakinthos has been well-studied for years. In fact, there was a film made only recently of the sperm whales in this area. These particular beached whales might even be part of that film.

Thanks Jenn, I kind of figured that the original suggestion was simply a hearsay but it does its damage. We do enough damage to our environment not to have to make up stuff and totally confuse real problems.

The Latter is pretty neat; showing how Africa bumps into Europe, forming the Alps, quite similar to India pushing up the set of wrinkles known as the Himalayas in Asia...
