Regional instrumental seismicity
This seismicity maps have been generated by concatenating the ISC catalogue (since 1964), the EMSC Euro-Med Bulletin catalogue and the EMSC Real Time catalogue. Therefore, they show the seismicity from 1964 until the earthquake occurrence.

I think it is TOTALLY worth some scientist - Researching THIS angle, I do not understand WHY they never have!! Seriously!! WHY... haven't they looked at beachings and quakes with the data between the two? Especially such a Large beaching! It makes sense, imagine sound waves under water of the earth grinding...... that would cause such pain to them.
It could actually help people if they took a SERIOUS look at some of these things!
Indonesia has raised to maximum its alert on the Mount Semeru volcano in East Java, warning of potentially dangerous lava flows, an official at the country's vulcanology centre said on Saturday.
The 3,376-metre (11,080-ft) Semeru is one of the most active volcanoes on Java island. Seven people were killed by the mountain's heat clouds in 1994.
The alert status was raised on Friday afternoon after the number of volcanic quakes indicated there may be a bigger eruption, said Surono, head of the country's vulcanology centre.
"We don't want to evacuate residents around the mountain, but we warn those carrying out activities such as sand mining to avoid rivers because of lava flows," said Surono, who goes by one name like many Indonesians.
You might think it's a pretty wacky idea. But it's got currency. Yet is it true? What is true is that on December 4, three weeks before the earthquake off Indonesia, an Indian academic, Dr Arunachalam Kumar, professor of anatomy at Kasturba Medical College at Mangalore in Karnataka, posted a note about a recent whale-stranding in Tasmania, and its possible implications, on a "listserve", an e-mail distributor, hosted by Princeton University.
About 120 whales stranded and died in Australia at the end of November and 50 pilot whales died on a Coromandel beach at the same time.
Kumar is a well-known figure in India. An amateur naturalist of some repute and a prolific author, he is a larger-than-life character, frequently in the press.
"It is my observation, confirmed over the years, that mass suicides of whales and dolphins that occur sporadically all over the world, are in some way related to change and disturbances in the electromagnetic field co-ordinates and possible realignments of geotectonic plates thereof," he wrote.
"Tracking the data and plotting the locales of tremors and earthquakes, I am reasonably certain that major earthquakes usually follow within a week or two of mass breaching of cetacians [sic]. I have noted with alarm, the last week report of such mass deaths of marine mammals in an Australian beachside. I will not be surprised if within a few days a massive quake hits some part of the globe. The interrelationship between the unusual 'death-wish' of pods of whales and its inevitable aftermath, the earthquake, may need a further impassioned and unbiased looking into."
There's no doubt that he posted his note on December 4. To read it in the listserve itself, go to new-lists.princeton.edu/listserv/nathistory-india.html and click on "December 2004". In reading it, many are likely to experience a rising of the hair on the back of the neck.
According to Chinthamani, the professor "wrote that he had made a five-year record of dates and locales of whale strandings, plotted their locales, and correlated them to occurrences of upheavals on land or undersea, and had observed a remarkable connection between the events. In fact, Kumar never mentioned anything as precise as a five-year record.

Australia does not get earth quakes - no fault lines as it sits right in the middle of its own tectonic plates.
Beachings are confused sonar - look for navy operations, chinese, us subs etc.
"To get more than one species is unusual," he said. "When you do, you get more suspicious because it means that they might have been driven. It does make us worried. We are certainly going to call for a very thorough investigation."
Military sonar has been strongly linked to several strandings, particularly of deep-diving species such as pilot whales. Other human noises that could have frightened or disorientated the animals include industrial activities.
Another prime suspect among the possible causes is climate change, which scientists fear may be causing whales and dolphins to get close to unfamiliar coastlines.
Several species have migrations that take them close to the Tasmanian shore - 80 per cent of Australian strandings take place in Tasmania - and changes in water temperature caused by climate change could be driving them off their usual routes.
However, Dr Simmonds accepted that an explanation for the stranding could equally well be natural, such as the marine animals making a simple navigational error.
Factors leading to natural strandings are little understood but researchers believe that they are likely to be linked to group behaviour.
"Pilot whales are one of those species that do tend to feature in mass strandings, which is probably because they are a very social species," Dr Simmonds said. "Out at sea there's nowhere to hide but behind each other, so when one gets into trouble the others follow."
It is the fourth time in the past few months that a large stranding has taken place on Tasmania's coast. Chris Arthur, of the Parks and Wildlife Service, said: "This last summer has been a particularly demanding one."
Ninety-seven animals of two species - long-finned whales and bottlenose dolphins - were stranded in November 2004 on King Island.
An earth tremor has hit parts of Victoria and Melbourne's eastern suburbs for the second time in a fortnight.
Geoscience Australia says the quake had a preliminary magnitude of 4.6 and hit at Korumburra, about 100 kilometres south-east of Melbourne, at about 4:30 pm.
Initial reports said the tremor lasted between four and 10 seconds.
