A great earthquake with magnitude 8.8 rocked the coast of Chile at 6:34 GMT this morning, generating a potentially dangerous tsunami that is racing across the Pacific Ocean. The great quake is the 7th most powerful tremor in world history (Figure 1). Preliminary tsunami wave heights for the California coast near Santa Barbara are 2 - 2.5 feet. The wave is expected to arrive between 12:15 - 12:35 pm PST. The tsunami is expected to arrive in Hawaii between 11:05 - 11:42am HST, with a wave 8.2 feet high expected in Hilo, on the Big Island. A tsunami from the 9.5 Magnitude 1960 earthquake in Chile killed 61 people in Hilo. Today's quake was so strong, that it triggered a seiche in Lake Pontchartrain, Louisiana, over 4,500 miles (7,000 km) away. The lake sloshed back and forth, creating a wave 0.4 - 0.51 feet on either side of the lake.

Tofino, British Columbia 1.7 ft

Today's great quake occurred at the boundary between the Nazca and South American plates about 325 km southwest of the capital Santiago (population 5.3 million). The depth was estimated at 35 km. At least four aftershocks of magnitude 6 or higher have occurred, the largest being a 6.9 aftershock. Fortunately, the area close to the epicenter is relatively sparsely populated, but there may be heavy damage in Concepción (est. pop. 300,000) and Chillan (est. pop. 170,000), which lie 115 km and 100 km to the south of the epicenter, respectively.

New York City slammed with its 4th largest snowstorm on record
The snow from the fourth extreme snowstorm to wallop the Northeast U.S. this winter dumped a remarkable 20.9" of snow on New York City's Central Park yesterday and Thursday. This is the 4th largest snowstorm for the city in recorded history. According to the National Weather Service, the top ten snowstorms on record for New York City's Central Park are:

26.9" Feb 11-12, 2006
26.4" Dec 26-27, 1947
21.0" Mar 12-14, 1888
20.9" Feb 25-26, 2010
20.2" Jan 7-8, 1996
19.8" Feb 16-17, 2003
18.1" Mar 7-8, 1941
17.7" Feb 5-7, 1978
17.6" Feb 11-12, 1983
17.5" Feb 4-7, 1920

The storm also helped New York City set a new all-time snowfall record for the most snow ever recorded in a month--36.9". The old record was 30.5", set in March 1896. However, the old Lower Manhattan WB Station recorded 37.9" in February 1894. Yesterday's snowstorm puts New York City's snow for the 2009 - 2010 season at 51.4", making it the 11th snowiest winter since 1869. Chris Burt, author of Extreme Weather, lists the city's all-time seasonal snowfall record at 81.5", set in the winter of 1867 - 1868. This measurement came before official records began in Central Park, and were done be the NY Park Commissioners (see "Annual Report NY Park Commissioners", 1868, by John B. Marie). The second snowiest winter in NYC occurred during the winter of 1995 - 1996, when 75.6" fell.

Destructive Winter Storm Xynthia battering Portugal and Spain
A powerful 969 mb low pressure system named "Xynthia" is rapidly intensifying of the coast of Spain, and stands poised to deliver a devastating blow to Portugal, Spain, and France today and tomorrow as it powers through Europe. Sustained winds of 60 mph (96 km/hr) were reported today at a Personal Weather Station in Costa del Morte, Spain. The pressure fell to 969 mb as Xynthia passed overhead. For comparison, Winter Storm Klaus had a minimum pressure of 967 mb. Klaus, which hit northern Spain and southwest France January 23 - 25, was Earth's most costly natural disaster of 2009, causing $5.1 billion in damage and killing 26. Models predict that Xynthia will continue to intensify today, reaching 962 mb as it moves into the west coast of France Sunday morning. Sustained winds of 50 - 65 mph (80 - 105 km/hr) with hurricane-force gusts up to 100 mph (160 km/hr) are possible along the north coast of Spain tonight and the west coast of France on Sunday as Xynthia barrels through. The storm is also bringing an exceptionally moist plume of tropical moisture ashore, as seen in precipitable water imagery from NOAA (Figure 4). This moisture is likely to cause moderate to severe flooding in portions of Europe over the weekend.

From MSNBC World Blog (This is actually good news)

Information from the U.S. military, filed by Jim Miklasewski | 12:21 p.m. ET

U.S. military officials say Chile has still not formally sought any US military assistance in response to the earthquake, "and frankly we don't expect them to ask."

As for the tsunami, U.S. Navy officials say they're expecting only a two 2-foot surge to hit the islands within hours.

As a result they have evacuated two military housing complexes on the Island of Oahu "as a precaution." The Navy is NOT removing any ships from ports and sending them out to sea.

Quoting Patrap:
"Seiche" is also a French term for a type of cuttlefish (Sepiida).

A seiche (pronounced /ˈseɪʃ/ "saysh") is a standing wave in an enclosed or partially enclosed body of water. Seiches and seiche-related phenomena have been observed on lakes, reservoirs, swimming pools, bays, and seas. The key requirement for formation of a seiche is that the body of water be at least partially bounded, allowing the formation of the standing wave.

The term was promoted by the Swiss hydrologist François-Alphonse Forel in 1890, who was the first to make scientific observations of the effect in Lake Geneva, Switzerland.[1] The word originates in a Swiss French dialect word that means "to sway back and forth", which had apparently long been used in the region to describe oscillations in alpine lakes.

Big quake question: Is nature out of control?
One scientist, however, says that relative to the time period from the mid-1970s to the mid-1990s, Earth has been more active over the past 15 years or so.

Even so, magnitude-8 earthquakes occur globally, on average, just once a year. Since magnitudes are given on a logarithmic scale, an 8.8-magnitude is much more intense than a magnitude 8, and so this event would be even rarer, said J. Ramón Arrowsmith, a geologist at Arizona State University.

Is Earth shaking more?
The Ryukyu Islands of Japan were hit with a 7.0-magnitude quake on Friday night. News of that tremor, the Haiti quake and now Chile may make it seem as if Earth is becoming ever more active. But in the grand scheme of things, geologists say this is just Mother Nature as usual.

"From our human perspective with our relatively short and incomplete memories and better and better communications around the world, we hear about more earthquakes and it seems like they are more frequent," Arrowsmith said. "But this is probably not any indication of a global change in earthquake rate of significance."

Coupled with better communication, as the human population skyrockets and we move into more hazardous regions, we're going to hear more about the events that do occur, Arrowsmith added.

However, "relative to the 20-year period from the mid-1970s to the mid 1990s, the Earth has been more active over the past 15 or so years," said Stephen S. Gao, a geophysicist at Missouri University of Science and Technology. "We still do not know the reason for this yet. Could simply be the natural temporal variation of the stress field in the earth's lithosphere." (The lithosphere is the outer solid part of the Earth.)

While the Chilean earthquake wasn't directly related to Japan's 7.0-magnitude temblor, the two have some factors in common.

For one, any seismic waves that made their way from Japan to the Chilean coast could play a slight role in ground-shaking.

"It is too far away for any direct triggering, and those distances also make the seismic waves as they would pass by from the Haiti or Japan events pretty small because of attenuation," Arrowsmith told LiveScience. (Attenuation is the decrease in energy with distance.) "Nevertheless, if the Chilean fault surface were close to failure, those small waves could push it even closer."

Colliding plates
The Chilean earthquake occurred at the boundary between the Nazca and South American tectonic plates. These rocky slabs are converging at a rate of 3 inches (80 mm) per year, according to the USGS. This huge jolt happened as the Nazca plate moved down and landward below the South American plate. This is called a subduction zone when one plate subducts beneath another.

(Over time, the overriding South American Plate gets lifted up, creating the towering Andes Mountains.)

The plate movement explains why coastal Chile has such a history of powerful earthquakes . Since 1973, 13 temblors of magnitude 7.0 or greater have occurred there, according to the USGS.

While early reports are encouraging about tsunami impact of this serious quake, we still need to keep guard, because the 1960 quake tsunami worst impact was Hawaii, especially Hilo and Japan.

78. Great info, Skye, all in one place.
Yep, Bordo -- we got it. I'm actually pretty good in an emergency... between "crash and burn" broadcasting, FEMA running and grinding us gerbils up, and CERT training -- well, even monkeys like me learn.

It's just the surge thing that was making me sound whacked... my son is at airport along with many others on Maui. For anyone not familiar, there aren't many roads, in fact, there's like one main one around the island. There's almost no roads inland, plus roads are blocked by emerg. mngmnt or some officials. I just sent my son back home for blankets, trash bags, and duct tape -- he had dumped the blankets/bed-roll to make room for friends he picked up. He has plenty of time to get them.

Garbage bags, of course, work for ground cover, under bedding, as tarps and as ponchos.

I think we're good.

The rumor mill is what is dangerous; my DIL was told 150-foot wave height. I assume some idiot got very confused and is spreading misinformation. This is when PIOs have to go into overdrive.

EVALUATION

SEA LEVEL READINGS CONFIRM THAT A TSUNAMI HAS BEEN GENERATED
WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE
APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL
CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND
SEVERITY OF THE THREAT.

A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THE
LARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARY
SIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROM
ONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, AND
THE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE.

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT.
THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE.

THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE PRODUCTS
FOR ALASKA...BRITISH COLUMBIA...WASHINGTON...OREGON...CALIFORNIA.

The following list gives estimated times of arrival for
locations along the North American Pacific coast from a
tsunami generated at the given source location. The
list is ordered by arrival time starting with the earliest.
Since tsunami speed is directly related to
water depth, tsunami ETAs can be computed independent of
tsunami amplitude. THE LISTING OF A TSUNAMI ARRIVAL TIME
BELOW DOES NOT INDICATE A WAVE IS IMMINENT. The listed arrival
time is the initial wave arrival. Tsunamis can be dangerous
for many hours after arrival, and the initial wave is not
necessarily the largest.

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.

A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE
CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD
COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE
INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS
CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST.
TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT
RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI
WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL
QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE
CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED
BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH
TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.

THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS

1105 AM HST SAT 27 FEB 2010

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

drgOd,

Thanks for that link. I feel pretty confident that we will be OK. If we see some surge, as they say we might, it will occur during our low tide. That is good timing! We also live in that big curve along the coast...which helps!

They even said they wouldn't vacate the beaches up in LA - although I can't imagine anyone would be out in this weather!

Thank you, that's very helpful. Scary as sh**, but helpful.

Son just called. Asked specifically about wave heights -- don't know why he's NOT on blog, lol -- I gave him link, sigh...gee, maybe he's busy...:)

Levi, Bordo, et al. --

Son is 5 blocks from beach. Is that enough, do you think? I'm thinking maybe, maybe NOT. I remember what Keys looked like from Wilma...


It depends how high up he is. If he's well above sea level then 5 blocks could be fine, but the terrain determines how far inland the water penetrates, and he needs high ground, no matter how far inland it is.

Your son needs to take ALL his important paperwork and take a day inland, like in the mountains, away from the beach. The waves may travel inland a great distance, more than blocks from the beach, maybe at elevation 1,000 ft up in the hills, away from everything!!!

I live in Seal Beach, which is just south of Los Angeles, and I just returned from a walk to the beach. I didn't notice any out of the ordinary wave heights or tides. Tide is somewhat high right now anyway. Of course, we are only under an tsunami advisory.

It poured here this morning, we caught a little break (that's when we went for our walk) and it's pouring outside again now.

We've been under one before - after the earthquake off Alaska - but they called that one off too.

Hope the world stays safe!

Distance from beach is NOT what is important. It's the height that need attention. These things can go hundreds of yards inland. 5 blocks is nothing.


OKEY DOKEY THEN.

Marlborough Sounds evacuations
Beach areas in the Port Underwood area of the Marlborough Sounds are being evacuated by police preparing for a tsunami

28 February 2010
Picton police are evacuating beach areas in the Port Underwood area of the Marlborough Sounds in preparation for the Tsunami.

Haka Haka bay resident, Alan Shannon, says a knock on the door about 4.30 this morning told them all to go to the top of the hill

Picton Harbour Master, Alex Van Wjngaarten, has advised the Tory Channel entrance in the Queen Charlotte Sound has been closed from 6 this morning.

An Interislander port security spokesperson says they have not been told yet if the Interislander sailing this morning will be cancelled.

New Zealand Civil Defence has issued a tsunami alert following an earthquake - measuring 8.8 on the Richter scale - off Chile.
