Magnitude 7.7 Quake Strikes Queen Charlotte Islands, Canada

Posted by feww on October 28, 2012

Earthquake Measuring 7.7 Mw Strikes Queen Charlotte Islands Region generating a tsunami

FIRE-EARTH Forecast: Mega Quake measuring at least 8.8Mw could strike the region in the coming weeks with a probability of 0.75.

The powerful quake struck off Canada’s Pacific coast at a depth of about 16 km generating a tsunami, which forced  the authorities in Hawaii to order more than 100,000 people evacuate the shorelines.

  • Dozens of aftershocks, including at least 10 shocks measuring ≥5.0Mw had occurred, as of posting.
  • A Geophysicist at Tsunami Warning Center said the tsunami had caught scientists by surprise, Reuters reported.
  • “We thought that the earthquake was on land and when we learned that it was deeper undersea and we gathered more information, we had no choice but to issue a warning,” he said.

The Largest Earthquake in Canada

Canada’s largest earthquake (magnitude 8.1) since 1700, occurred on August 22, 1949 off the coast of BC. It occurred on the Queen Charlotte Fault (Canada’s equivalent of the San Andreas Fault) – the boundary between the Pacific and North American plates that runs underwater along the west coast of the Queen Charlotte Islands off the west coast of British Columbia. The shaking was so severe on the Queen Charlotte Islands that cows were knocked off their feet, and a geologist with the Geological Survey of Canada working on the north end of Graham Island could not stand up. Chimneys toppled, and an oil tank at Cumshewa Inlet collapsed. In Terrace, on the adjacent mainland, cars were bounced around, and standing on the street was described as “like being on the heaving deck of a ship at sea”. In Prince Rupert, windows were shattered and buildings swayed. —Natural resources of Canada

Powerful Earthquake Strikes Tonga

Posted by feww on November 25, 2009

Earthquake Measuring Up to M 7.1 Strikes Near NUKU’ALOFA, Tonga

A powerful earthquake measuring up to 7.1 Mw struck  about 135 km (85 miles) ENE of NUKU’ALOFA, Tonga at a depth of 10 km on  November 24, 2009 at 12:47 UTC.

The quake was followed by at least two aftershocks, the stronger of which measured up to 5.8 Mw.

Tsunami Evaluation:

The Pacific Tsunami Warning Center/NOAA/NWS Evaluated the Tsunami Hazard as follows:

NO DESTRUCTIVE WIDESPREAD TSUNAMI THREAT EXISTS BASED ON HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

HOWEVER – EARTHQUAKES OF THIS SIZE SOMETIMES GENERATE LOCAL TSUNAMIS THAT CAN BE DESTRUCTIVE ALONG COASTS LOCATED WITHIN A HUNDRED KM OF THE EARTHQUAKE EPICENTER. AUTHORITIES IN THE REGION OF THE EPICENTER SHOULD BE AWARE OF THIS POSSIBILITY AND TAKE APPROPRIATE ACTION.

FEWW Comment: Does the SW Pacific region including Tonga, Fiji, and Samoan Islands regions act as a ‘planetary seismic shock damper?’  How much longer will the service last?

Strong Quake Strikes Fiji Region

Posted by feww on November 22, 2009

Earthquake measuring up to 6.5 Mw strikes Fiji Region

A strong earthquake measuring up to M 6.5 struck offshore Fiji Region at 17.789°S, 178.435°W at a depth  of about 520 km November 22, 2009 at 07:48 UTC.

The event occurred about 195 km SE of Taveuni volcano which last erupted about 1550 ± 100 yrs.

Taveuni, the 3-rd largest island in Fiji, is a large shield volcano that rises from the Pacific Ocean floor. A popular tourist destination, the Island has a population of less than 10,000.

Tsunami Information

The earthquake was located too deep to generate a tsunami.

Latest Earthquakes Magnitude 5.5 +

Posted by feww on September 19, 2009

Latest Earthquakes Measuring Magnitude 5.5 or Larger since September 18, 2009

The following significant earthquakes occurred within a 12-hour period.

The Bali Earthquake detailed below was reported as a Magnitude  6.0  shock by the  European-Mediterranean Seismological Center. 

GFZ Potsdam – Earthquake Bulletin
Region: South of Bali, Indonesia
Time: 2009-09-18 at 23:06:59.5 UTC
Magnitude: 5.9
Epicenter: 115.42°E 9.47°S
Depth: 77 km
Status: automatic

The quake was described as “very strong” by a number of people who sopke to the media. People were reportedly jumping from building and running away from their homes in panic after the quake struck. Up to a dozen people have been injured, some hurt jumping from buildings while others were hit by falling debris, according to news reports quoting officials.  No tsunami warning was issued.

An earthquake on the main Indonesian island of Java left more than 50 dead on September 2, 2009.

The 9.3 Mw Sumatra-Andaman earthquake which caused the 2004 Indian Ocean tsunami that killed an estimated quarter of million people in 11 countries, was the second largest earthquake recorded on a seismograph. The earthquake was also characterized by the longest ever duration of faulting lasting about 10 minutes, which made the entire planet to vibrate about 1 cm triggering earthquakes as far north as in Alaska.

FEWW Comments: More Mega-quakes should be expected in this region and other areas in the coming months. FEWW will post a separate [disturbing] forecast later.
