What was I saying about earthquakes and volcanic eruptions on another thread. Hope Hawaii goes unscathed.
Any follow-up? Did a tsunami actually occur?
They should give British Columbia back to the Columbians
Apparently Hurricane Sandy has been linked to the same area as the quake that hit near Haida Gwaii.

On news this evening here in Aus, a tsunami of 2metres is expected in about an hour. Lets hope it’s not that severe.
All I know is there is no damage, but many people have noted that there have been waves, shimmies and jolts. Highest wave noted was 45cm. Time wise 8pm to about 8:15pm British Columbia time. Since it is dark many can’t see if there was damage to the area, where it happened. They have noted that there has been a change in sea levels and the currents have changed, but that was the latest update on the news here in Alberta where I live.
Meanwhile on the sun http://sohowww.nascom.nasa.gov//data/REPROCESSING/Completed/2012/c2/20121026/20121026_1112_c2_512.jpg
Patrick, where did you get that info? I’ll google but I’m inland –
No tsunami warning for Australia yet? That’s looking on the Australian tsunami warning website
I wonder what the Italians are doing – perhaps issuing their own tsunami alert in case it gets into the Atlantic, then through the straits of Gibraltar ….

My local in Victoria at sea level remained unscathed.
I blame Bush.
Oh know.. global warming sea level rise !!!
According to Sky news, The first waves of around one meter are hitting Hawaii now, the live images are looking good so-far to pass with very little damage.
Live tide guages … Hawaii tide gauge site …
Nawiliwili guage on Kauai is northenmost guage (but on East shore so levels smaller) and shows 5 waves so far – 3rd wave was peak as expected …. max peak appx +.65 meter with -.22 trough …
Kahului Harbor shows larger – appx +1.25 meter peak and -0.25 trough through two main waves (with possibly two minor – peak still growing
Kahului shows 3rd main wave lower … Nawiliwili thru 7 waves amplitude + and – peak to trough decreasing …
Drag the yellow window at top to right end to see the tsunami section … and/or drag graph itself to right to see …
Change of local sea levels is caused by land height changes not unusual during an earthquake. Let’s hope that the tsunami expected is short lived.
I’m in British Columbia on mid-Vancouver Island so this caused some initial concern when I saw the alert.
However, the alert was for Northern Vancouver Island to parts of Alaska. Here at least, nothing of note.
Commentary and Background – I posted this some time ago.
The Cascadia Fault offshore Vancouver Island has experienced 13 great earthquakes in the last 6000 years, or one every 500 years on average. The last big one occurred 311 years ago in 1700, so another could happen at any time. Low-lying areas are particularly vulnerable and we will have less than one hour’s warning between the seismic event and the tsunami.
I would not assume that our current tsunami warning system is capable of such a rapid response.
p.s.
Earthquakes tend to happen in bunches.

The M9 Cascadia Megathrust Earthquake of January 26, 1700
http://earthquakescanada.nrcan.gc.ca/histor/15-19th-eme/1700/1700-eng.php
At 9PM on January 26, 1700 one of the world’s largest earthquakes occurred along the west coast of North America. The undersea Cascadia thrust fault ruptured along a 1000 km length, from mid Vancouver Island to northern California in a great earthquake, producing tremendous shaking and a huge tsunami that swept across the Pacific. The Cascadia fault is the boundary between two of the Earth’s tectonic plates: the smaller offshore Juan de Fuca plate that is sliding under the much larger North American plate.
The earthquake shaking collapsed houses of the Cowichan people on Vancouver Island and caused numerous landslides. The shaking was so violent that people could not stand and so prolonged that it made them sick. On the west coast of Vancouver Island, the tsunami completely destroyed the winter village of the Pachena Bay people with no survivors. These events are recorded in the oral traditions of the First Nations people on Vancouver Island. The tsunami swept across the Pacific also causing destruction along the Pacific coast of Japan. It is the accurate descriptions of the tsunami and the accurate time keeping by the Japanese that allows us to confidently know the size and exact time of this great earthquake.
The earthquake also left unmistakeable signatures in the geological record as the outer coastal regions subsided and drowned coastal marshlands and forests that were subsequently covered with younger sediments. The recognition of definitive signatures in the geological record tells us the January 26, 1700 event was not a unique event, but has repeated many times at irregular intervals of hundreds of years. Geological evidence indicates that 13 great earthquakes have occurred in the last 6000 years.
We now know that a similar offshore event will happen sometime in the future and that it represents a considerable hazard to those who live in southwest B.C. However, because the fault is offshore, it is not the greatest earthquake hazard faced by major west coast cities. In the interval between great earthquakes, the tectonic plates become stuck together, yet continue to move towards each other. This causes tremendous strain and deformation of the Earth’s crust in the coastal region and causes ongoing earthquake activity. This is the situation that we are in now. Some onshore earthquakes can be quite large (there have been four magnitude 7+ earthquakes in the past 130 years in southwest B.C. and northern Washington State). Because these inland earthquakes can be much closer to our urban areas and occur more frequently, they represent the greatest earthquake hazard. An inland magnitude 6.9 earthquake in 1995 in a similar geological setting beneath Kobe, Japan caused in excess of $200 billion damage.
Main energy pretty much past Hawaii it would appear …
Is there any suspicion that Tony Abbott is responsible?
