I was just watching a show on the Tsunami, explaining why, and how it happened. In the end they mention how this will happen again due to a Volcano in the Canary Island which is VERY weak and cracking, and will slide into the ocean if theres an earthquake or even a tiny errunption.
So I googled it and found this article which is not very old:

That Canary Island Time Bomb
By James Donahue

Autumn 2004

If you think the big tides and flooding from the hurricanes are bad, consider a “mega tsunami,” a massive wall of water sweeping across the Atlantic at speeds of over 500 miles-per-hour and striking the entire east coast of the United States.

Not only affecting the Americas, but this same wave also would slam into the British Isles, the entire western coasts of Europe, Africa, South America and the Caribbean Islands, destroying everything in its path.

Scientists warn that this kind of disaster is poised to really happen because of a large piece of a volcano that is poised to plunge into the sea.

All it would take, said Bill McGuire, director of the Benfield Greig Hazards Research Centre, University College London, is an earthquake or eruption of the volcano located on La Palma Island, in the Canarie chain just off the African coast.

The danger is quite real, McGuire warns.

He said the potential for disaster was set up when the volcano, Cumbre Vieja, last erupted. The blast caused a huge part of its western flank to crack. Since then, a massive part of that mountain, an estimated 500 billion tons of it, has been poised to slide into the sea.

Measurements over the years indicate that this part of the mountain has been slowly sliding toward the Atlantic ever since.

“When it goes, it will likely collapse in about 90 seconds,” McGuire said.

When it goes, it will fall into water almost four miles deep and create an undersea wave unlike anything ever seen in recorded history. McGuire, said the wave would be about 330 feet high when it strikes land.

“When one of these comes in, it keeps on coming for 10 to 15 minutes,” he said. “It’s like a huge wall of water that just keeps coming.”

The destruction from such a wave would not be limited to just the immediate coastal areas, but reach inland until the power of the water is exhausted. Entire coastal cities could be destroyed.

The wave could be formed and strike these areas with such speed that there would be little time for evacuation. Millions would be caught almost unaware.

McGuire said computer models show that the super waves could cross 4,000 miles of ocean and reach the Caribbean islands and the eastern seaboard of the United States and Canada within nine and 12 hours. Europe and Africa would be struck much earlier.

Worse hit will be harbors and estuaries that channel the waves inland.

Even though the potential for disaster is known, McGuire said little has been done to monitor the geological activity on La Palma. He said a few seismometers are set up on the western flank of the island, but they don’t provide the information needed to predict an eruption.

“It’s really a worrying situation,” he said. “We may not get the notice we need.”

And the counter argument:


Most recently, the Discovery Channel has replayed a program alleging potential destruction of coastal areas of the Atlantic by tsunami waves which might be generated in the near future by a volcanic collapse in the Canary Islands. Other reports have involved a smaller but similar catastrophe from Kilauea volcano on the island of Hawai`i. They like to call these occurences "mega tsunamis". We would like to halt the scaremongering from these unfounded reports. We wish to provide the media with factual information so that the public can be properly informed about actual hazards of tsunamis and their mitigation.

Here are a set of facts, agreed on by committee members, about the claims in these reports:

- While the active volcano of Cumbre Vieja on Las Palma is expected to erupt again, it will not send a large part of the island into the ocean, though small landslides may occur. The Discovery program does not bring out in the interviews that such volcanic collapses are extremely rare events, separated in geologic time by thousands or even millions of years.

- No such event - a mega tsunami - has occurred in either the Atlantic or Pacific oceans in recorded history. NONE.

- The colossal collapses of Krakatau or Santorin (the two most similar known happenings) generated catastrophic waves in the immediate area but hazardous waves did not propagate to distant shores. Carefully performed numerical and experimental model experiments on such events and of the postulated Las Palma event verify that the relatively short waves from these small, though intense, occurrences do not travel as do tsunami waves from a major earthquake.

Tidal Waves are caused by shifts on the ocean floor (earthquakes). Dropping an object into the water doesn't have the same effect. A meteor's speed is what makes it's impact so different than a sinking island.

I took GEOL 2209, hahahah, and i dont thing Calgarians have anything to worry about. Vancouver.... lets just say i wouldn't buy property there...:eek:
