Common toads appear to be able to sense an impending earthquake and will flee their colony days before the seismic activity strikes. The evidence comes from a population of toads which left their breeding colony three days before an earthquake that struck L'Aquila in Italy in 2009.
Marine animal experts are trying to prevent a mass stranding by up to 100 pilot whales in South Uist in the Western Isles. The whales were spotted in Loch Carnan on Thursday afternoon and about 20 were said to have had cuts to their heads. It is thought the injuries may have been caused by attempts to strand themselves on the rocky foreshore of the sea loch. Rescuers said inflatable pontoons for refloating whales were on the way. The pod has been moving back and forth from the shore and rescuers said the animals were "very vocal", which may be a sign of distress. Members of the British Divers Marine Life Rescue (BDMLR) fear the whales could die in a massive beaching - which could be Scotland's largest stranding.
Earthquakes, like the one that struck in Christchurch, New Zealand yesterday, rank among the most devastating natural disasters, capable of leveling cities and causing extensive loss of life -- largely because they are so unpredictable. On Sunday, however, less than 48 hours before the quake, 107 pilot whales beached themselves and died along the nation's shores, a phenomenon that biologists have yet to fully understand. The proximity of the two events, in both time and location, have sent the Web in a frenzy over whether they are related -- and whether strandings can provide precious foresight before disaster strikes.
Relationship of LIP's to extinction events:
Eruptions or emplacements of LIP's appear to have, in some cases, occurred simultaneously with oceanic anoxic events and extinction events. The most important examples are the Deccan Traps (Cretaceous–Tertiary extinction event), the Karoo-Ferrar (Pliensbachian-Toarcian extinction), the Central Atlantic Magmatic Province (Triassic-Jurassic extinction event), and the Siberian traps (Permian-Triassic extinction event). Several mechanisms are proposed to explain the association of LIP's with extinction events. The eruption of basaltic LIP's onto the earth's surface releases large volumes of sulfate gas, which forms sulfuric acid in the atmosphere; this absorbs heat and causes substantial cooling (e.g., the Laki eruption in Iceland, 1783).
Oceanic LIP's can reduce oxygen in seawater by either direct oxidation reactions with metals in hydrothermal fluids or by causing algal blooms that consume large amounts of oxygen.

But why the mass beachings?
I accept that the correlation between animal behaviour and earthquakes is very tenuous (at this time) but the OP has brought to our attention something that may well have passed under the radar of anyone trying to correlate data and information that may prove to be significant in the future.
I live not too far from this event, I watch the BBC news and others and I did not know about this.
Still say good post and may be relevant in the weeks or months ahead.

"Whether or not these faults and this beaching incident are related remains to be seen. "
Exactly!
That's why this post has value. It is flagging up an event, which may have gone unnoticed by the many people all over the world looking for any indicators that 'may' precede an earthquake.
It may not come to anything but that in itself has value as this event can be matched against others where earthquakes happen shortly after beachings.

I have often thought about this, having read the report it does seem the whales are determined to go in a particular direction, determined to beech they say in the report. I am no marine biologist so I don't really know how pilot whales navigate, but I am presuming it is magnetic like birds, if so could increased stress on the tectonic plates create shifts in the magnetic field and throw their navigation off?
It would explain why these events happen quite often in a near time frame to an earthquake happening
A volcanic eruption believed to be more powerful than last year's flight-halting blast has closed airspace across Iceland.
But experts say the latest rupture should not affect international flights.
The North Atlantic island's most active volcano, Grimsvoetn, located at the heart of its biggest glacier Vatnajoekull, started to spew smoke and lava late Saturday.
Within an hour, the plume of smoke had rose to an altitude of 11km (6.8 miles).
The eruption comes just over a year after the nearby Eyjafjoell erupted - the first volanco blast at the Eyjafjallajokull glacier since 1823, and Iceland's first since 2004.
It briefly forced 600 people from their homes in the area but shut down large swathes of European airspace for almost a month amid fears the volcanic ash floating across the skies would wreak havoc on aircraft engines.
Icelandic Meteorological Office geophysicist Gunnar Gudmundsson said the Grismvoetn burst would not be of the same scale but could interfere with domestic flights.
"I don't expect this will have the same effect as Eyjafjo
