And I would like to know what '188 day cycle' Yamkin is referring to. Asking such a simple question is hardly being 'picky' now, is it? A simple explanation, along with supporting data, will be fine...

I'm sure that some will blindly accept it but then that wouldn't be a scientific approach.....

If this were to create a tsunami, can anyone tell me how long it would take to travel and hit ?

That obviously depends on your location from the point of origin but they typically travel at 750 kilometers per hour so in many cases you don't have long. Your best bet is to jump in a boat and head out to sea but unfortunately, and tragically, most don't have a choice.

Thanks Weather Ship. I was wondering if and when it may hit Aceh as they seem to be in the possible firing line.

[cartedj]

Couldn't get our prescision balances to stabalise in our factory in Oxfordshire. Phoned up the service companies site and theirs were all over the place as well in their workshop in Oxford. This was about 10.30am. Must have been one hell of a shock. I thought the technician was pully my wire when he told me about the earthquake. Balances have now settled back down again.

Indonesian quake reawakens tsunami fears in Asia

HONG KONG — In nations around the Indian Ocean, thousands scrambled for higher ground Wednesday after powerful quakes triggered fears of a disaster in a region all too familiar with the power of a tsunami.

Warnings that destructive waves could tear into coastal regions sparked mass evacuations from India to Kenya, reawakening painful memories of the catastrophic 2004 tsunami that claimed nearly a quarter of a million lives. The 8.6-magnitude undersea quake and strong aftershocks hit off Indonesia's Sumatra island just a few hundred kilometres from the epicentre of that deadly event, with witnesses saying they felt the ground shake for well over a minute.

In Indonesia's Banda Aceh, which was devastated by the 2004 Boxing Day tsunami, people raced from tall buildings and headed inland as warnings of another destructive tsunami were issued across the region. The alerts were cancelled several hours later after the waves proved to be limited and at their highest less than a metre. But in the hours before the all-clear, there were chaotic scenes as people grabbed their families and raced through crowded streets, with motorbikes and cars jostling for space.

"It lasted a very long time," said Australian Steven Sewell in Padang, West Sumatra where he runs a surfing charter business, adding that the quake sparked fear in the streets.

"We headed to higher ground above the river for two hours then the second one (aftershock) hit. "The second one was almost as long as the first one. Just prolonged shaking from side to side... Pretty scary when your pregnant wife's in the car." In Sri Lanka which was also hard-hit by the 2004 disaster, thousands fled coastal homes after a tsunami warning was issued across the island and residents were urged to move inland to avoid being hit by any large waves. "There is a near panic situation," a resident in Trincomalee contacted by telephone said, adding that the port city was packed with last-minute shoppers trying to stock up before the traditional New Year on Friday.

Malaysian state news agency Bernama said the quake was felt across the country including in the capital Kuala Lumpur, and the northern state of Perlis where panicky residents rushed from apartment blocks. Buildings swayed as far away as the Thai capital Bangkok. Thailand's National Disaster Warning Centre advised people in the area to move to higher places and stay as far away as possible from the sea. Australian Bonnie Muddle, vacationing on the Thai resort island of Phuket, said people were being evacuated from popular tourist areas including Krabi and Phang Nga Bay amid rumours that towering waves up to six metres high were barrelling towards them."Everyone is getting a little concerned over here," she told AFP.

The December 26, 2004 disaster was triggered by a massive 9.1-magnitude earthquake off Sumatra which caused a tsunami that wrought devastation across the Indian Ocean, killing an estimated 220,000 people. Last year, a 9.0-magnitude earthquake caused a tsunami and nuclear disaster in Japan, killing some 19,000 people.

Any earthquake reports from England tonight? Could it have been what cause the massive explosion an hour ago?

[Crepuscular Ray]

Nothing yet on EMSC about any notable earthquake. Apparently the MoD and British Geological Survey are both investigating.
