Alaska: 7.1 Mag Quake, Local Tsunami Warning Issued

UPDATED: Cancellation #3 issued 09/2/2011 at 3:57AM AKDT

The Tsunami Warning is canceled for the coastal areas from Unimak Pass, Alaska (80 miles NE of Dutch Harbor) to Amchitka Pass, Alaska (125 miles W of Adak).


NO destructive tsunami has been recorded, and NO tsunami danger exists along the coasts of the U.S. west coast states, Alaska, and British Columbia. Local authorities can assume all clear upon receipt of this message.

 

It now appears that the USGS has downgraded the earthquake to a 6.8.

# 5805

 

A strong 7.1 magnitude earthquake has struck in the Fox islands of Alaska in the past hour. Quakes of that size are capable of generating small to medium sized (usually localized) tsunamis. 

 

At this point, no Pacific-wide destructive tsunami is expected to have been generated.

NOAA’s West Coast and Alaska Tsunami Warning Center has issued the following statement:

 

A Tsunami Warning is now in effect which includes the coastal areas of Alaska from Unimak Pass, Alaska (80 miles NE of Dutch Harbor) to Amchitka Pass, Alaska (125 miles W of Adak).

<SNIP>

At 2:56 AM Alaskan Daylight Time on September 2, an earthquake with preliminary magnitude 7.1 occurred 45 miles/72 Km southeast of Amukta Pass, Alaska . (Refer to the United States Geological Survey for official earthquake parameters.) Earthquakes of this size are known to generate tsunamis. If a tsunami has been generated, the waves will first reach Adak, Alaska at 3:52 AM AKDT on September 2. Estimated tsunami arrival times and maps along with safety rules and other information can be found on the WCATWC web site.

The WCATWC will likely update this report shortly.

Here is the latest advisory from the West Coast and Alaska Tsunami Warning Center.

To: U.S. West Coast, Alaska, and British Columbia coastal regions


From: NOAA/NWS/West Coast and Alaska Tsunami Warning Center


Subject: Tsunami Watch and Advisory #3 issued 03/10/2011 at 11:33PM PST


UPDATED MAGNITUDE TO 8.8

The Tsunami Advisory continues in effect for the coastal areas of Alaska from Chignik Bay, Alaska to Attu, Alaska.


The Tsunami Watch continues in effect for the coastal areas of California, Oregon, Washington, British Columbia and Alaska from the California-Mexico border to Chignik Bay, Alaska.

A Tsunami Advisory means that a tsunami capable of producing strong currents or waves dangerous to persons in or very near the water is expected. Significant, widespread inundation is not expected for areas under an advisory. Currents may be hazardous to swimmers, boats, and coastal structures and may continue for several hours after the initial wave arrival.

A Tsunami Watch means that all coastal residents in the watch area should prepare for possible evacuation. A tsunami watch is issued to areas which will not be immediately impacted by the tsunami. Watch areas will either be upgraded to warning or advisory status, or canceled.

At 9:46 PM Pacific Standard Time on March 10, an earthquake with preliminary magnitude 8.8 occurred near the east coast of Honshu, Japan . (Refer to the United States Geological Survey for official earthquake parameters.) This earthquake has generated a tsunami which could cause damage to coastal regions in a warning or advisory. The waves are expected to first reach Shemya, Alaska at 12:13 AM AKST on March 11. Estimated tsunami arrival times and maps along with safety rules and other information can be found on the WCATWC web site.

# 5368

 

Tsunami waves of up to 4 meters reportedly struck the coast shortly after the (now upgraded) 8.9 quake off the coast of Honshu.  Farms and houses are reportedly washed away by the incoming waves, and more than an hour after the quake fresh waves continue to come in.

 

Quake damage reports are just beginning to come in, but at this point they look to be significant. 

 

Live streaming video from NHK World with English news commentary is available at:

In the hour or so since the major quake, several very strong aftershocks have been reported.

The world is waiting for damage reports, and word of any tsunami generated, in the wake of an extremely powerful earthquake that struck off the coast of Honshu, Japan mid afternoon local time Friday.

 

Immediate had estimated the magnitude range at 7.9, but the USGS is now showing it at 8.8 , and the depth at 24.4 km.   Adjustments to magnitudes often occur when more data is received.

This is the latest of a series of earthquakes in this region that began less than 48 hours ago with a 7.2 magnitude quake, followed by many aftershocks.

 

The Pacific Tsunami Warning center has issued the following statement:

Tsunami watch issued after Japan earthquake

Updated: Mar 11, 2011 1:42 AM EST Friday, March 11, 2011 1:42 AM EST

EWA BEACH (HawaiiNewsNow) -- A Tsunami Watch has been issued for the state of Hawaii following an 8.8 magnitude earthquake off the east coast of Honshu, Japan.

 

Scientists at the Pacific Tsunami Warning Center in Ewa Beach said that based on available data, a tsunami may have been generated by the quake. They said the earliest that tsunami waves could reach Hawaii would be at 2:59 a.m. Friday.

 

This is obviously a breaking news story, and I’ll have updates as they become available.   I’ll also be looking for online streaming coverage, and will post any links I can find.

Tsunami Warning For The Pacific

 

 

 

# 4388

 

In the early hours of this morning a massive 8.8 magnitude quake struck southern Chile, causing what early reports suggest is extensive damage, and generating a Tsunami.

 

This Tsunami – or rather, series of Tsunamis – are traveling across the Pacific at roughly the speed of an airliner.   Their impacts won’t be felt in places like Hawaii, New Zealand, and Indonesia for hours.

 


It is impossible to forecast with any accuracy how large these tsunami waves will be when they reach these locations, but we can estimate the arrival time.

 

The first of these Tsunamis is expect to strike the Hawaiian islands a little after 11am, HST.

Huge earthquake batters Chile, 78 dead

SANTIAGO, Chile (Reuters) - A massive magnitude-8.8 earthquake struck south-central Chile early on Saturday, killing at least 78 people, knocking down buildings and triggering a tsunami.

 

President Michelle Bachelet said there were 78 confirmed deaths and that more were possible. Telephone and power lines were down, making it difficult to make an early assessment of the damage, but serious damage was reported in two southern cities.

 

"Never in my life have I experienced a quake like this, it's like the end of the world," one man told local television from the city of Temuco, where the quake damaged buildings and forced staff to evacuate the regional hospital.

 

The U.S. Geological Survey said the earthquake struck 56 miles northeast of the city of Concepcion at a depth of 22 miles at 3:34 a.m. (1:34 a.m. ET).

Early reports, such as the number of deaths, amount of damage, and size of tsunamis generated are all subject to revision.
