BBC News (http://news.bbc.co.uk/2/hi/americas/8540289.stm):


A massive earthquake with a magnitude of 8.8 has hit central Chile, killing at least 78 people, ministers say.

The quake struck at 0634 GMT about 115km (70 miles) north-east of the city of Concepcion and 325km south-west of the capital, Santiago.

President Michelle Bachelet declared a "state of catastrophe" in affected areas and appealed for calm.

Tsunami warnings have been issued for Hawaii, Australia, New Zealand and Pacific island nations.

A tsunami has been observed in Chile, Valparaiso, 2.6 meters higher than normal sealevel. There is a tsunami advisory (http://wcatwc.arh.noaa.gov/2010/02/27/725245/05/message725245-05.htm) for the US west coast. Estimated arrival times (http://wcatwc.arh.noaa.gov/2010/02/27/725245/05/webeta725245-05.txt).

Pacific Tsunami Warning Center warning (http://www.prh.noaa.gov/ptwc/messages/hawaii/2010/hawaii.2010.02.27.114829.txt).


EVALUATION

A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG
COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION
SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.
[...]
THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS

1119 AM HST SAT 27 FEB 2010

Map (http://wcatwc.arh.noaa.gov/2010/02/27/725245/05/ttvu725245-05.jpg) of arrival times.

Hard to tell if this will be dangerous or not.

Some reports of 40 m waves on some of the Pacific islands.

Been up all night and into this morning watching the news. This is the 7th largest earthquake in recorded history. I'm really, really hoping the generated Tsunami isn't looking to break records, too. :scared:

It was felt here too.

I have a strong connection with that region. I travel there frequently and have many friends there. I´ll try to contact them to make sure evrything is ok [although I know via Twitter that central Chile is out of power].

Tsunami waves have been reported in southern Chile.

My thoughts are with them.

Destructive waves reported in Juan Fernandez Island, 600 km off the Chilean coast. The quake rocked all South America south of the paralel 20.

Doesn't vantage point usually imply high up? That's a pretty good place to be when expecting a tsunami.

This is terrible.

Is this about the Andes getting taller? After the Loma Preita quake parts of the Coast Range rose almost two meters.

Yes, that´s the dynamics that form the Andes. Television images of this quake show areas that were uplifted ~3m.

The epicentre is being reported as 35km deep, which would put it on the convection zone.


This earthquake occurred at the boundary between the Nazca and South American tectonic plates. The two plates are converging at a rate of 80 mm per year. The earthquake occurred as thrust-faulting on the interface between the two plates, with the Nazca plate moving down and landward below the South American plate.

No luck yet with web servers from observatories well north of Santiago (i.e. Cerro Tololo). We have a support engineer just leaving from the mountain today; no word yet on what happened there. Pretty far from the epicenter, but I once felt a much weaker one that far away while sleeping in La Serena.

Can't we send some news reporters down to the beach to get some video of the wave coming in?

Reports of tsunami can be seen here (http://www.prh.noaa.gov/ptwc/?region=1) (latest text version at top of list). Shows Acapulco reporting 0.2 meters (but cautions that this is not exactly the free-ocean full amplitude) at 1549 UT (1 hour 7 minutes after the Galapagos Islands).

Actually, it says .07m or .2ft at DART Manzanillo. Acapulco was .16m or .5ft.

I was rounding :) That was the latest value shown when I last looked. Now it shows Manzanillo proper at 1705 UT.

Any reports on the coastal effects and breaking heights?

I see the news coverage is up to its substandard fare. Meterologists trying (and failing) to explain how earthquakes work. CNN found the fact that houses are connected by roads newsworthy, while FOX tells us that most of the country's infrastructure is composed of roads and railroads. Oh, and FOX got some actual experts to interview - specifically the "United Geological Survey". I'm sure the United Federation of Planets' Geologists will get right on this problem and solve it - presumably with a mix of transporter technology, neutrinos and the main deflector dish.

As far as the tsunami goes, it looks like it's going to be a non-event.

Seen some images out of Hilo, water running in and out of the Bay. So far, max height was 3 feet, which will not cause any damage.

Saw a video of Coconut Island (a park on the Hilo waterfront) and the little foot bridge to it. I've been on the foot bridge many times but never seen any whitewater under it before, like today when the water was running out.

Hey, I know exactly the bridge you are talking about, we visited that park when we were in Hilo many years ago and I took a bunch of pictures.

Glad to hear things are OK.

Okay, new pics in from Talcahuano and they had sigificant damage from the Tsunami, but that's pretty close to the epicenter.

(Hilo (http://en.wikipedia.org/wiki/Hilo), a city in Hawaii.) I guess if the tsunami is pretty tame on Hawaii, it might not be such a big danger for other places. Then again, some of those atoll islands don't have any elevation at all... Hope they don't get hit.

Tsunami warning was lifted about 45 mins ago on Hawai'i. They had about four tsunami waves, they showed the water going in and out on the beaches (and some morons standing on the beach watching it) and covering up a reef on the KHON live feed I was watching. Looks like it arrived about an hour later than anticipated, and was about half the height (around 3ft/1m).

No damage reported, thankfully. I guess some people will start bleating about how it was all a false alarm, but they'd be wrong - the tsunamis DID hit, just not as big as feared. Hawai'i was lucky this time.

That would be consistent, as far as I remember a tsunami's speed depends on its size. The larger they are, the faster they move.

That's a 150 foot cliff of barely compressed sand. I was thinking of Milagra Ridge. More than twice the height and it's rock and quartz. It would have given me a view of the entire gulf of the Farallons.

When I get un-angry enough to write about it, I'll put it in it's own thread so as to neither highjack this one nor give the appearance I was making light of this horrible event.

That's the problem with tsunamis, you can't track them real time. They are predicted by computer models and are only as good as the data fed to the model. Much better predictions are made in retrospect when all the data is in.

Serious answer - I never heard a thing, so I assume the answer is no, particularly after Hawaii getting off easy.

Funny answer - Yeah, a lot of car recalls for Toyota. ;)

The coast of Japan was hit, and I'm not sure but they were about 1 m or maybe 2 m. But 2 m can be a bit destructive. There was some flood damage in cities along the coast.

Somebody earlier mentioned 40 m tsunami. I haven't heard anything about that, but it would be a tremendous thing. If Pacific islands were struck by waves that big, it would be incredibly damaging.

Damages amount to 25% of the GDP, and 1,600,000 people [10% of the country´s population] are homeless. Chile´s president, who refused international aid at first, is now reconsidering the offers. The blow was harder than previously thought.

International markets record a spike in copper prices.

Tsunami pictures of the water sloshing around Hilo Bay (http://www.instantimagegallery.com/iig/a/97/167551;jsessionid=9CF210E5EF27E2F4591F17470C6FB36A ?state:cat/Catalog=BrO0ABXcgAAAAAgEAByRCb3JkZXIAEG9yaWdpbmFsQ 2xpZW50SWRzcgARamF2YS5sYW5nLkludGVnZXIS4qCk94GHOAI AAUkABXZhbHVleHIAEGphdmEubGFuZy5OdW1iZXKGrJUdC5Tgi wIAAHhwAAAAYXcMAAAJY2F0YWxvZ0lkc3EAfgAAAAAAWQ%3D%3 D).

I heard one comment that in addition to the height being only about 3 feet, the other thing that negated damage there was the wave crest to crest distance was short enough that Hilo Bay didn't get into a resonance (which can increase the height of the tsunami).
