Certainly was a biggy, apparently it was felt upto 2000 km's away, I wonder whether such a significant plate movement will cause further downstream large quakes.

I've got the BBC news on my other PC monitor and they arn't really mentioning it at all.

Lots of reports(unconfirmed), of hospitals damaged, bridges down, death toll already of 20 etc.

I think I'll start a new thread specifically for it so that this one doesn't get bogged down by it.

Mondy - I think the tide gauge that recorded that was in an earthquake hit area.

Just watching TV and all the eyes are on Hawaii, however looking at live tidal data from California, the fluctuations in height there are much more obvious. Be interesting to see how long it takes for the press to notice this one.

Been working for a long time, 7 days a week on a hectic job in the middle east so back in the UK on a well earned break but now finding myself shouting at the TV. The press both UK and American, really have no idea what a tsunami is or what they are looking for. Also be interesting to see if some of the real-time tidal monitoring equipment my company have in the Malacca Straits at the moment picks anything up.

Nothing really out of the ordinary for NZ and surrounding islands. Indeed the Chatham's recorded a "tsunami" of 20cms many hours ago. Seriously, the Sky news presenter said: "tsunami of 20cms"..

On this link ( http://tidesonline.nos.noaa.gov/ ) which is a good example of the media NOT noticing?

PS, tnx for the links - they are all very good and interesting.

A raise of 20cm at Chatham Island but that drop of 1.5m is quite impressive

You have to remember it's not quite clear how some of this data is taken, if its a 1 minute average every 10 minutes, then you could be introducing aliaising issues.

ANKARA, Turkey — A strong earthquake, with a preliminary magnitude of 6, hit eastern Turkey on Monday, killing at least 41 people and knocking down houses in at least six small villages, the government said.

The quake affected villages near the town of Kovancilar, toppling stone or mud-brick homes and minarets of mosques, officials and media reports said. The worst-hit area was the village of Okcular where some 17 people were reported killed.

The government's crisis center said around 100 people were also injured in the quake, which occurred at 4:32 a.m. (0232 GMT, 9 p.m. EST Sunday) in Elazig province, about 550 kilometers (340 miles) east of Ankara, the capital, and caught many people in their sleep. It was centered near the village of Basyurt, and was followed by more than 30 aftershocks, the strongest measuring 4.1, according to Istanbul's Kandilli Observatory seismology center. Emergency workers were trying to rescue four people from debris, Gov. Muammer Erol said. CNN-Turk television said the dead included four young sisters trapped in the rubble.

"Everything has been knocked down, there is not a stone in place," said Yadin Apaydin, administrator for the village of Yukari Kanatli, where he said at least three villagers died.

Authorities blocked access to Okcular village, to facilitate the entry and exit of ambulances and rescue teams on the village's narrow roads. Relatives rushed to the village for news of their loved ones.

"The village is totally flattened," Okcular's administrator Hasan Demirdag told private NTV television.

The quake was felt in the neighboring provinces of Tunceli, Bingol and Diyarbakir where residents fled to the streets in panic and spent the night outdoors.

Some of the injuries occurred during the panic, when people jumped from windows or balconies. Dogan news agency footage showed people bringing in the injured to hospitals by cars and taxis.

Kandilli Observatory's director, Mustafa Erdik, urged residents not to enter damaged homes, warning that they could topple from the aftershocks, which could last for days. Television footage showed rescue workers and soldiers at Okcular lifting debris as villagers looked on. Two women sat on mattresses wrapped in blankets. Turkey's Red Crescent organization began setting up tents in the region.

Earthquakes are frequent in Turkey, much of which lies atop the North Anatolian fault. In 1999, two powerful earthquakes struck northwestern Turkey, killing about 18,000 people.

In 2007, an earthquake measuring 5.7 damaged buildings in Elazig, briefly trapping a woman under debris. In 2003, an earthquake measuring 6.4 magnitude collapsed a school dormitory in the neighboring province of Bingol province, killing 83 children. The collapse was blamed on poor construction.

and BBC now reporting it

http://news.bbc.co.u...cas/8603073.stm

A 7.2 magnitude earthquake has hit the Mexican peninsula of Baja

California, US officials say, and has been felt in Los Angeles and even in

Nevada. The quake struck at 1540 (2240 GMT), 26km (16 miles) south-west of

Guadalupe Victoria in Baja California, at a depth of 32km, said the US

Geological Survey. There have been reports of broken windows and some

structural damage but no word of casualties or major damage. In San

Diego, tall buildings were seen swaying. Bridge checksMexico's

National Seismological Institute reported no casualties in the north-western

state. The quake caused buildings to sway in the

Mexican city of Tijuana, where Easter celebrations were interrupted as families

rushed for open ground.
