Cascadia May Rupture Less Often Than Previously Thought

[color=cyan]According to a study published in the Canadian Journal of Sciences, Seafloor cores taken from the Effingham inlet indicate that the Cascadia Subduction Zone may not rupture every 300 years. Instead they posit that it may have a non-conforming rupture timeline which could be anywhere from the currently thought 300 year interval to a 1,000 year interval. Which would beg the question, is the Pacific Northwest on a 300 year cycle for rupture or on a longer cycle which could postpone a rupture for another 700 years?


Past Mega-Quakes Left Mark on Canadian Coast

[color=cyan]This study could defintely breathe more life into research in the Canadian region and may lead to a better picture of subduction zone behavior in Cascadia which could aide in the creation of prediction models and preparedness scenarios.

Woah, we jumped the gun on predicting the timeline of a mega-disaster?
Who would have guessed?

The core samples they discuss in the program, "Monster Quake, are we there yet," suggest there are quake clusters that occur every 300 hundred years but there can be another 700-1000 years between clusters. There are 4-5 quakes per cluster, and the 1700 quake was #5 indicating the cluster may be complete. However, in the clusters, the last quake is most often the biggest, as much as 3 times bigger than all the rest, and the last quake in this cluster was not any bigger. So the question was, is the last quake still coming, which could be as much as 3 times bigger than the Japan quake, or is the most recent cluster now complete, in which case we may be clear for hundreds of years.

Just google it and see for yourselves.

Greetings,

I saw the article and realized we might have a lot more time out here on the West Coast before the big one hits. Another 700 years gives us a great chance for the oceans to rise significantly and be able to flood even farther inland. Oh well, it gives emergency planners more time to get the resources they need to save a lot of lives and investors to find new ocean front property to sell. However, I don't see it creating any boom in AZ or NV property prices just yet. My best,
