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.

Preliminary tsunami amplitude forecasts:

La Jolla, CA 2.3 ft
Los Angeles, CA 2.0 ft
Malibu, CA 2.6 ft
Pt. San Luis, CA 2.3 ft
Half Moon Bay, CA 2.6 ft
Crescent City, CA 1.7 ft
Morro Bay, CA 2.2 ft
Santa Monica, CA 3.3 ft
San Francisco, CA 0.7 ft
Pismo Beach, CA 4.6 ft

Hilo, HI 8.2 feet 11:5am HST
Honolulu, HI 1.6 ft 11:37am HST
Kahului, HI 7.2 ft 11:26am HST
Nawiliwili, HI 3.0 ft 11:42am HST
Haleiwa 1.6 ft
Kawaihae 2.0 ft

Port Orford, OR 0.7 ft

Moclip, WA 1.3 ft

Seward, AK 1.3 ft
Stika, AK 1.3 ft
Kodiak, AK 2.3 ft

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.

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.

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.

Quoting Levi32:


Again I'm not an expert but tsunamis and hurricane storm surges are very different. A hurricane doesn't exert force on the entire water column, but a tsunami does. Therefore the resulting wave and the force associated with a tsunami is much different and more powerful than a storm surge.

Right now we're talking about a wave equivilant in HEIGHT to a Cat 1 or 2 hurricane, but the force behind it is far more powerful, and will cause more damage and impact than the storm surge of a Cat 1 or 2 hurricane striking Hawaii. However, as long as people move inland as they are told, they will be fine, as I'm sure your son and daughter and law will be.


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

Are there similar guess-timate tools for tsunamis?

that is, can someone tell me how far inland water damage could go on Hawaiian Islands... and/or all the warning areas? In weather-for-dummy-worried-Mom-speak, please. And again, thanks for putting up with and helping AIM, today.

Relax, first of all! Secondly, I am sure you have contacted your son and daughter in law. Let them know what is going on, to leave coastal areas ASAP and to take this very seriously.

The waves of a tsunami come in 2 or more waves ususally. The water recedes from the coast as the wave approaches, due to the friction from land interaction. The wave or waves crash onshore shortly thereafter. NOONE IN THEIR RIGHT MIND needs to be ANYWHERE near a beach when the tsunami waves crash onshore!!

Wave heights can vary greatly. I wish NOT to venture a guess. HOWEVER, this may be similar to the tsunami in 1946, that hit Hilo, HI.

Thanks, Levi...the wave heights you all and Dr. Masters have posted, often and well and I sure don't mind any repeats.

It's the surge that is driving me NUTSO. Would it do me any good at all to use hurricane surge guesstimates as a very general guideline?

I can't get into the main tsunami site so I don't know if there are any better graphics than the ones already posted, but how high the waves are and how far inland they penetrate varies greatly depending on where you are on the coastline of Hawaii. Each island is expecting different wave heights varying from 1 foot to 8 feet high. The terrain and shape of the coastline determines how high the waves are and how far inland they penetrate.

Awesome stuff..

I looked at the lake Buoys and sure nuff,..she sloshed back and forth BIG time.

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.

All depends on a lot of factors AIM.

Most notable is Tsunami Height,..angle of approach,coastal shape,etc..

What is going to be interesting is that we will see the arrival Live on TV later.

When we're talking about 6700 miles, adjustments of a few minutes are to be expected. This is only 14 minutes earlier than the previous estimated time, and times will vary depending on which Hawaiian island you are on.

Why you can't surf a tsunami

You can't surf a tsunami because it doesn’t have a face. Many people have the misconception that a tsunami wave will resemble the 25-foot waves at Jaws, Waimea or Maverick's, but this is incorrect: those waves look nothing like a tsunami. On the contrary, a tsunami wave approaching land is more like a wall of whitewater. It doesn’t stack up cleanly into a breaking wave; only a portion of the wave is able to stack up tall. Since the wave is 100 miles long and the tail end of the wave is still traveling at 500 mph, the shore end of the wave becomes extremely thick, and is forced to run far inland, over streets and trees and houses.

If you're a surfer, you know how little control you have if your board is in whitewater. On a tsunami, there's no face, so there's nothing for a surfboard to grip. And remember, the water isn't clean, but filled with everything dredged up from the sea floor and the land the wave runs over--garbage, parking meters, pieces of buildings, dead animals. This is not what you want to be caught paddling around in. You can't duck-dive because the entire water column is in motion, not just the top few feet. You can't exit the wave, either, because the trough behind is 100 miles away, and all that water is moving towards you.

Just heard from an expert on Fox News that statistically it would not be unexpected to see an aftershock as high as magnitude 7.8 before it's all over.
Yup, just posted it a couple minutes ago. If we do end up seeing a 7.8 (more or less) then it looks like some more tsumani's will happen.
